Basic Steps to Onboard a Machine as a Compute Provider on NuNet:

1. Download and install the Device Management Service (DMS): Install the DMS on your machine, which will enable you to connect to the NuNet platform and make your computing resources available for running ML jobs.

2. Download and install the Compute Provider Dashboard (CPD) : Install the Compute Provider Dashboard on your local machine, making it accessible for you to manage and monitor the ML jobs assigned to your machine and receive NTX tokens for your contributions.

3. Onboard your machine: Please refer to our CPD and NuNet CLI user guides for complete details on how to onboard your machine.

   1. Specify your Cardano address: During the DMS onboarding process, provide the Cardano address of the wallet connected to the Compute Provider Dashboard when using the NuNet CLI. This address will be used for receiving NTX token rewards for your deployment contributions. For Public Alpha we are using the PreProd Cardano Network.

   2. Allocate your Resources: Completing the onboarding process for your machine makes it available for receiving ML job requests while connected to the NuNet platform. Onboarding allows providing the necessary information about your machine to NuNet's Distributed Hash Table, or DHT, such as the available CPU or GPU resources, RAM, and other hardware details. This information will be used to match your machine with ML jobs requiring appropriate resources to deploy them.

4. Create Cardano testnet wallet: Make sure you choose the testnet network when setting up your wallet (Eternl or Nami wallet). The name of the specific Cardano testnet would be PreProd Cardano Network.

5. Set up your wallet: Connect your Cardano wallet to the Compute Provider Dashboard at localhost:9992. Ensure that your wallet has enough tADA for transaction fees. This wallet will be used to receive the NTX tokens on the PreProd Cardano Network as a reward for providing compute resources on NuNet. Make sure the wallet address on this wallet is the same as you specified in Step 3.1 when requesting your NTX tokens.

6. Receive ML jobs: Your machine will be automatically assigned ML jobs based on the resources needed and your machine's availability.

7. Receive NTX token rewards: Upon the successful completion of an ML job, you will receive NTX token rewards in your connected wallet. The amount of NTX tokens received will be based on the resources contributed and the terms set by the service provider.

8. Continue providing compute resources: Keep your machine connected to the NuNet platform and continue providing compute resources for ML jobs, earning NTX tokens as a reward for your contributions.

For a more comprehensive overview, you can always refer to our user guides in the Components Installation section. [Add YouTube video on running the Public Alpha as a Compute Provider.]

Estimating Resource Types

In order to effectively allocate resources for machine learning/computational tasks on the NuNet platform, it is essential to categorize the different resource types available. We have classified resource types into three main categories based on the capabilities of the machines and GPUs:

1. Low Resource Usage: This category represents low-end machines with low-end GPUs.

2. Moderate Resource Usage: This category represents medium-end machines with medium-end GPUs.

3. High Resource Usage: This category represents high-end machines with high-end GPUs.

The pseudocode provided outlines a function called estimate_resource, which is designed to estimate the resource parameters for different categories of machines based on their resource usage type. The function accepts a single input, resource_usage, which can take on one of three possible values: "Low", "Moderate", or "High".

The function then checks the value of resource_usage and, depending on the category, sets the minimum and maximum values for the CPU, RAM, and GPU VRAM, as well as the estimated levels of GPU power and GPU usage. These values are assigned based on the specific resource usage category:

1. For "Low" resource usage, the function sets lower values for CPU, RAM, and GPU VRAM, as well as lower GPU power and usage levels. This category represents low-end machines with low-end GPUs.

2. For "Moderate" resource usage, the function sets medium values for CPU, RAM, and GPU VRAM, as well as medium GPU power and usage levels. This category represents medium-end machines with medium-end GPUs.

3. For "High" resource usage, the function sets higher values for CPU, RAM, and GPU VRAM, as well as higher GPU power and usage levels. This category represents high-end machines with high-end GPUs.

Finally, the function returns a dictionary containing all the estimated parameters for the given resource usage category. By using this function, the NuNet platform can estimate resource parameters for machines in different categories, helping to efficiently allocate resources for machine learning tasks based on the specific requirements of each job.

Calculating Resource Prices

For each resource type, resource prices are calculated in the NuNet ML on GPU API. These functions help estimate the cost of using different types of machines for executing machine learning tasks. The process involves the Estimated Static NTX.

1. Estimated Static NTX is calculated using the user's input for the estimated execution time of the task and the chosen resource type (Low, Moderate, or High). The function Calculate_Static_NTX_GPU(resource_usage) calculates this value based on these inputs and returns the Estimated NTX.

This function works to estimate and calculate resource prices for various types of machines, ensuring that users are billed fairly based on the actual resources used during the execution of their machine learning tasks.

Reporting Task Results

The pseudocode for "Reporting Task Results" describes two functions used in the NuNet ML on GPU API that allow users to monitor the progress of their machine learning tasks and access the results.

1. Upload_Compute_Job_Result() is a function that regularly updates the task's progress. It runs in a loop and performs the following steps every 2 minutes until the job is completed or the off-chain transaction of the Estimated Static NTX is done:

   • Wait for 2 minutes.

   • Save the machine learning log output as a file that can be appended with new information.

   • Upload the file to the cloud, making sure that only an authenticated user can access it.

   This function allows users to keep track of their tasks and view intermediate results during the execution.

2. Send_Answer_Message() is a function that provides a unique link to the WebApp, which helps users track their tasks. It performs the following steps:

   • Retrieve a unique URL (permalink) for each machine learning job.

   • Send the permalink from the Decentralized Management System (DMS) to the WebApp as an answer message.

   This function enables users to access their task's progress updates and results using the provided link.

In summary, these functions work together to ensure users can monitor their machine learning tasks' progress and access the results in a user-friendly and organized manner.

This is the description of the current NuNet architecture for testing the ML use case. The business goal of implementing this use case is to allow users to onboard both latent GPU and CPU resources to be used by service providers to run compute jobs (in this case, ML jobs) on the NuNet platform and be compensated in NTX (NuNet’s Utility Token) for the job. For Public Alpha we are using the PreProd Cardano Network.

These are the NuNet core elements for the Public Alpha:

Decentralized Components:

• In NuNet, the term service provider refers to the individual or group that wants to run a job on NuNet’s decentralized community hardware.

• The term compute provider refers to an individual on the community who has on-boarded their devices onto the NuNet platform.

• The term DMS refers to Device Management Service, which is essentially the NuNet platform itself. It is the lightweight peer-to-peer connection between services and providers.

• Service Provider Dashboard is the application that service providers use to deploy jobs on NuNet and to lock funds on the smart contract.

• Compute Provider Dashboard is the application that compute providers use to claim their tokens for work carried out on their devices.

Centralized Components:

• ​​NuNet Oracle and Haskell Server are components responsible for locking funds on the smart contract and validating results of compute jobs prior to the withdraw transaction. For Public Alpha we implemented a smart contract on the PreProd Cardano Network.

• Control Server is responsible to any control functionalities necessary on NuNet. On this use case, it servers the captcha functionality.

• NuNet Network Status displays real-time statistics about all computational processes executed on the network and their telemetry information.

NuNet is building a globally decentralized computing framework that combines latent computing power of independently owned compute devices across the globe into a dynamic marketplace of compute resources, individually rewarded via a multi chain Tokenomic ecosystem based on the NuNet Utility Token (NTX).

Being a multi-sided platform, NuNet will support a variety of decentralized services that are defined by use cases. These use cases will be decided on by both community and partnerships, they currently range from distributed machine learning jobs to decentralized Cardano nodes. The requirements of the use cases will drive the development of the core platform, this will ensure features that support actual use cases are prioritized and add utility to the network.

NuNet is part of the SingularityNET eco system and was originally intended to support the decentralized operation of their global AI market place. NuNet has also sought to integrate with other decentralized platforms, the diagram below shows some of the platforms we could integrate with as we build out our vision. As with the use cases, as partnerships are formed with other platforms the core infrastructure will be developed in order to support interoperability.

Here's a basic step-by-step guide on how to use a tADA (testnet ADA) faucet and obtain tADA tokens:

1. Go to the Cardano Developer Portal: The Cardano Developer Portal is the official resource for Cardano developers and contains information on how to use the Cardano testnet, including a list of tADA faucets.

2. Get tADA from a faucet: You can obtain tADA from the Cardano Developer Portal that includes a . For more instructions on how to use one, see our .

3. Enter your testnet wallet address: Copy and paste your testnet wallet address into the field provided on the tADA faucet website. Make sure you are using a testnet wallet address and not a mainnet address, as the two are not interchangeable.

4. Solve the captcha: Some tADA faucets require you to solve a captcha or complete a task to prove you are a real person and not a bot.

5. Request tADA: Click on the "Request tADA" button on the faucet website. Your tADA tokens should be sent to your testnet wallet address within a few minutes.

6. Check your testnet wallet balance: Open your testnet wallet and check your balance to make sure the tADA tokens have been successfully deposited.

Remember, tADA tokens are not real ADA tokens and have no real-world value. They are only intended for testing purposes on the Cardano testnet. Additionally, some tADA faucets have limits on how many tokens you can request per day or per IP address, so be sure to check the faucet's rules and guidelines before requesting tokens.

Before running the tests, consider the following:

• If you are a compute provider, please make sure to backup any important data you might have before onboarding your machine as this is a testing phase.

• We use centralized components (Oracle, Control Server, Stats Network) running on our servers. Check if any configuration changes are needed to use these components.

• Use Eternl or Nami wallets for these tests. Make sure you have enabled single address mode if using Eternl.

• Ensure you have mNTX and tADA in your wallet. To get mNTX on the PreProd Cardano network, follow the Guide. For tADA, follow the Guide.

• For a basic outline on how to use a Cardano testnet, you can use the . The Cardano address provided during DMS onboarding should match the wallet connected to the dashboard.

• Note that compute providers would have add a collateral amount of around 5 tADA to interact with the NTX smart contract when using the Computer Provider Dashboard (CPD).

• To check if one machine can see the other, follow the instructions in the respective component documentation.

1. Download and install a testnet wallet: You can choose from Nami or Eternl. Make sure to select the testnet network option during the installation process.

2. Get testnet ADA: You can obtain testnet ADA from a testnet faucet, which is a service that provides free testnet tokens. You can learn more about .

3. Explore the testnet: Once you have your testnet wallet set up and testnet ADA in your account, you can start exploring the testnet network. You can send and receive transactions, create test tokens, and interact with smart contracts.

4. Join a testnet community: You can join the Cardano testnet community on forums like Reddit or Discord to connect with other developers and users, ask questions, and share your experiences.

5. Test our service/compute provider dashboards: The Cardano testnet is an ideal environment to test the dashboards before deploying them on the mainnet. You can use the testnet to identify bugs, test functionalities, and optimize our applications' performance.

6. Keep your testnet wallet safe: Although testnet tokens have no real-world value, you should still keep your testnet wallet secure. Make sure to use a strong password and never share your private keys or seed phrases with anyone.

Public Alpha is released with the ML use case, which allows users to run simple open source machine learning training on NuNet on-boarded computers and pay for the compute in NTX. We can use widely-used machine learning libraries, such as TensorFlow, PyTorch, and scikit-learn, ensuring that users can effortlessly integrate their preferred tools and frameworks. Moreover, the platform provides the flexibility to run jobs on either CPUs or GPUs, catering to various computational needs and budget constraints.

Designed with a user-centric approach, the Service Provider Dashboard has a simple interface that allows users to easily submit their ML models, define resource usage based on their job requirements, and keep track of their job's progress in real-time. This level of transparency and control empowers users to manage their machine learning jobs effectively and efficiently, ultimately facilitating and accelerating the development & deployment of innovative AI solutions.

For Public Alpha we implemented a smart contract on the PreProd Cardano Network to lock service provider NTX funds and reward compute provider users for the use of their resources.

You need to choose one role to play on this use case: you can be a that will requires to run a ML job on NuNet’s decentralized community hardware or you can be a who has on-boarded their devices onto the NuNet platform and will be compensated in NTX (NuNet’s Utility Token) for running the ML job requested by some service provider.

During this testing you can contribute in NuNet's development by reporting bugs and suggesting improvements. Please, refer to this documentation about the contribution guidelines:

Basic Steps to Run an ML Job on NuNet as a Service Provider:

1. Download and install the Device Management Service (DMS): on your machine, which will enable you to request ML jobs by connecting you to compute provider machines that are onboarded on the NuNet platform.

2. Download and install the Service Provider Dashboard (SPD): on your local machine, making it accessible for you to submit and monitor your ML jobs. No sign-up or NuNet account is needed.

3. Obtain compute resources: Open your preferred browser and visit localhost:9991 to specify the type of compute resources you require (CPU or GPU) and the amount of resources needed for your ML job.

4. Define your ML job: Specify your ML model URL, and provide any additional dependencies required for the execution of the ML job.

5. Set up your wallet: Connect your Cardano wallet (Eternl or Nami wallet) to the Service Provider Dashboard. Ensure that your wallet has enough ADA and NTX tokens for running the ML job and covering transaction fees. For Public Alpha we are using the PreProd Cardano Network.

6. Set a budget: Determine the maximum amount of NTX tokens you are willing to spend on the ML job. This budget will be locked in the smart contract on the PreProd Cardano Network as a guarantee for the compute providers.

7. Submit your ML job: Review your job configuration and submit the ML job to the NuNet platform. The platform will automatically match your job with suitable compute providers based on the resources needed.

8. Monitor your job: Track the progress of your ML job through the Service Provider Dashboard. You can check the log outputs of your job every 2 minutes since your job begins. Please wait for around 5 minutes for the first log to appear when deploying new ML jobs.

9. Review the results: Once the ML job is completed, you can download the output data and review the results. The locked NTX tokens will be released and distributed as a reward to the compute providers who contributed resources to your job.

10. Repeat the process (optional): If you have more ML jobs to run, you can follow the same steps to execute them on the NuNet platform, utilizing its decentralized computing resources.

To get mNTX (mock NTX) on the PreProd Cardano network, follow the below instructions on how to use the mNTX faucet:

• To use the NTX faucet on the Cardano Blockchain, follow these basic instructions:

  1. Create a Cardano wallet: If you don't have a Cardano wallet already on the PreProd Cardano network, create one using Eternl or Nami wallet applications. Make sure to securely store your seed phrase, as it is crucial for recovering your wallet.

  2. Find your wallet address: After creating your wallet double check you are on the preprod network, locate your Cardano wallet address. It typically starts with "addr_test1" and is followed by a long string of alphanumeric characters. in most wallets you find it by clicking on receive. Copy this address to use it in the next step.

  3. Join and Whitelist: and head to the relevant testing stage. Fill out the Google Form linked with your wallet address, Discord Name and GitLab name. We will use the wallet address provided to reward contributions both on Discord and GitLab. *Please note this may take some hours to receive mNTX to discourage spamming.

  4. Access the NTX faucet: Visit the NTX faucet's website provided by the NuNet team. . Note only whitelisted addresses will be able to receive tokens.

  5. Connect your Cardano wallet: click the connect wallet button and select the wallet you would like to use from the dropdown then click the mint mNTX button. (NOTE: please doublecheck this is the wallet you entered in the google form and that it is on the cardano preprod testnet)

  6. Sign the transaction: When you click the mint mNTX button it should open your wallet and ask you to sign a transaction. (note you should have some test ADA in your wallet before you do this if you dont have it already go )

  7. Faucet response: if it all went well then you should see a transaction hash, you can copy this and check on you may also receive a message saying you are not whitelisted, if this is the case please ensure you submitted the google form and have received notification that you were successfully whitelisted in discord. If you are still getting some sort of error message please go to discord for help.

  8. Check your wallet balance: After submitting your request, wait for a few minutes and then check your wallet application to confirm the receipt of mNTX tokens. It might take some time for the transaction to be processed, depending on the network's congestion.

  9. Use your mNTX tokens: You can now use the mNTX tokens in your wallet for testing or participating in the NuNet platform's services.

  Keep in mind that the mNTX tokens received from the faucet are intended for testing and development purposes. They may not hold any real-world value outside of the test environment or PreProd Cardano network.

Introduction

This manual provides instructions on how to use the NuNet Command Line Interface (CLI) to onboard a device, manage resources, wallets, and interact with peers.

Getting Started

1. Open the terminal and run the following command to access the CLI:

nunet

Usage

The CLI provides several commands and options for managing your device on the NuNet platform. The general syntax is:

nunet [OPTIONS] COMMAND

Commands

Here's the complete list of the command line options that can be used with the CLI:

• capacity: Display capacity of device resources

• wallet: Get Current Wallet Address

• onboard: Onboard the device to NuNet

• info: Get information about the currently onboarded machine

• onboard-gpu: Install NVIDIA GPU driver and Container Runtime

• onboard-ml: Prepare the system for Machine Learning with GPU

• resource-config: Change the configuration of onboarded device

• shell: Send commands and receive answers to a vm instance via DMS

• peer: Interact with currently visible peers

• chat: Start, Join, or List Chat Requests

• log: Returns the path of an archive containing all log files

Let's look into each of them and how they work.

Onboarding a Device

1. Check the available resources on your device by running the following command:

nunet capacity --pretty --available

1. If you don't have an existing wallet address, create a new one using either Ethereum or Cardano blockchain (We currently recommend using Cardano at the moment as this is the primary blockchain for testing and will be the focus for our Public Alpha) but have included both as NuNet is a multichain protocol and will support many chains in the future:

• For Cardano (we use this the our current testing):

nunet wallet new --cardano

When we support other blockchains in the future, you would simply need to change the blockchain name when creating a wallet through the above command.

Make sure you backup the mnemonic and wallet address for safe keeping. Do not share it with anyone. This is the same wallet address that you would be providing on the Compute Provider Dashboard.

1. Onboard your NVIDIA or AMD GPU

Note: You can skip this step if you don't have a GPU on your compute provider machine. If you are using a mining operating system such as HiveOS, only the NVIDIA container runtime would be installed, as it comes bundled with both NVIDIA and AMD drivers preinstalled.

Install the NVIDIA/AMD GPU driver and container runtime. To run this command, use the following command:

nunet onboard-gpu

For NVIDIA GPUs, the above command will work on both native Linux (Debian) and Windows Subsystem for Linux (WSL).

For AMD GPUs, the command will work only on native Linux (Debian), as there is currently no support on WSL.

NuNet's GPU onboarding also checks for Secure Boot if applicable, with the necessary messages to help the user. You can either choose to sign it with a machine owner key (MOK) if enabled, or keep it disabled in the BIOS.

After onboarding the GPU, it is recommended to reboot your machine with the following command:

reboot

1. Onboard your device to the NuNet platform using the following command:

nunet onboard -m <memory in MB> -c <cpu in MHz> -n nunet-test -a <address> [-C] [-l]

Replace <memory in MB>, <cpu in MHz>, and <address> with the appropriate values based on your device's resources (noted in onboarding step 1) and your wallet address.

For example:

For a machine with a local IP address use this syntax

nunet onboard -m 4000 -c 15000 -n nunet-test -a addr1q8pakf7kuac2fupvvwym4nq9rvu80vd5cvdtp2h0gpg8ppeetw8gxhrfckc4q3gjdg2eprnezpyx6sjauqj4mevleavql8n8kd -l

For a machine with a public IP address use this syntax

nunet onboard -m 4000 -c 15000 -n nunet-test -a addr1q8pakf7kuac2fupvvwym4nq9rvu80vd5cvdtp2h0gpg8ppeetw8gxhrfckc4q3gjdg2eprnezpyx6sjauqj4mevleavql8n8kd 

• The -C option is optional and allows deployment of a Cardano node. Your device must have at least 10,000 MB of memory and 6,000 MHz of compute capacity to be eligible.

• The -l option is optional but important. Use -l when running the DMS on a local machine (e.g., a laptop or desktop computer) to enable advertisement and discovery on a local network address. Do not use -l when running the DMS on a machine from a datacenter.

1. Prepare the system for Machine Learning (For GPU machines only)

Prepare the system for machine learning with GPU. We include this step to reduce the time for starting jobs because of large-sized GPU based ML images of TensorFlow and PyTorch. To do this, use the following command:

sudo nunet onboard-ml

The above command preloads (downloads) the latest ML on GPU images for training/inferencing/computing on NuNet.

1. Wait a few minutes for components to start and peers to be discovered.

2. Check your peer information and the peers your DMS is connected to by running the following commands:

​ You can lookup connected peers. To list visible peers, use the following command:

nunet peer list

​ To know you own peer info, use:

nunet peer self

If you see other peers in the list, congratulations! Your device is successfully onboarded to NuNet. If you only see your node, don't worry. It may take time to find other peers, especially if your device is behind symmetric NAT.

1. At any time after onboarding, you can also check how much resources had been allocated to NuNet previously with the following command:

nunet capacity --pretty --onboarded

To check your machine's full capacity, you can always use:

nunet capacity --pretty --full

Temporarily Pausing and Unpausing Onboarding

Sometimes, you may need to temporarily pause onboarding. You may want to do this if you need to use all of your device's resources, troubleshoot or perform maintenance tasks on your machine. The steps below provide a simple explanation of how to pause and unpause the DMS onboarding process using two commands.

Pause the Device Onboarding Process

To pause the DMS onboarding process, you can use the following command:

sudo systemctl stop nunet-dms

This command will temporarily stop the onboarding process.

Unpause the Device Onboarding Process

After you've paused the onboarding process and completed any necessary tasks, you can resume the process with the following command:

sudo systemctl start nunet-dms

This command will unpause and resume onboarding, allowing your device to once again find, and be seen by other peers on NuNet.

Important Note

If you do not manually unpause the onboarding process, it will automatically resume after a reboot or when the device powers up after being shut down.

Remember to always use these commands responsibly and only when needed, as interrupting the onboarding process may lead to unexpected behavior or issues with NuNet's decentralized peer-to-peer communication system on the device.

Enter a NuNet Peer's Shell

You can also send commands and receive answers to a VM instance via DMS. To do that, use the following format:

nunet shell --node-id <node-id>

The node-id can be obtained from the nunet peer list command. For example:

nunet shell --node-id Qmd8GeqGmdkQc5arhEs4i9tPRFNJoFLLURsBZsY9Riu4Kw

Chat with Peers

To start a chat with a peer, use the following format:

nunet chat start <node-id>

For example:

nunet chat start Qmd8GeqGmdkQc5arhEs4i9tPRFNJoFLLURsBZsY9Riu4Kw

To list open chat requests:

nunet chat list

To clear open chat requests:

nunet chat clear

To join a chat stream using the request ID:

nunet chat join <request-id>

The request-id mentioned above can be obtained from the nunet chat list command stated earlier.

Collect Logs

You can return the path of an archive containing all NuNet log files. To run this command, use:

nunet log

This should return the path to the archive containing the log files, such as /tmp/nunet-log/nunet-log.tar.

Display NuNet System Configuration with ML Readiness

Get information about the currently onboarded machine. To run this command, use the following command:

nunet info

Onboard NVIDIA/AMD GPU

Install the NVIDIA/AMD GPU driver and NVIDIA container runtime. To run this command, use the following command:

nunet onboard-gpu

This command will work on both native Linux (Debian) (both NVIDIA and AMD GPUs) and WSL (NVIDIA GPUs only) machines. It also checks for Secure Boot if necessary.

Prepare the System for Machine Learning

Prepare the system for machine learning with GPU. We include this step to reduce the time for starting jobs because of large-sized GPU based ML images of TensorFlow and PyTorch. To do this, use the following command:

sudo nunet onboard-ml

The above command preloads (downloads) the latest ML on GPU images for training/inferencing/computing on NuNet.

Check the GPU status in real time

To use this option, add the -gpu or the --gpu-status flag to available command like this:

nunet capacity --gpu-status

This allows you to check NVIDIA/AMD GPU utilization, memory usage, free memory, temperature and power draw when the machine is idle or busy.

Check the availability of CUDA and Tensor Cores

To use this option, add it to the capacity command like this:

nunet capacity --cuda-tensor

As a shorter alternative, you can also use -ct. To perform this check, the command leverages the NuNet PyTorch NVIDIA container used for onboard-ml.

Check the availability of ROCm and HIP

To use this option, add it to the capacity command like this:

nunet capacity --rocm-hip

As a shorter alternative, you can also use -rh. To perform this check, the command leverages the NuNet PyTorch AMD container used for onboard-ml.

How to Use the Service Provider Dashboard?

To use the Device Management Service (DMS) with Cardano, make sure your service provider machine connects with at least two DHT peers on NuNet. You can check this by using the nunet peer list command after you've set up your machine for a while.

Once confirmed, you can ask to run an ML job. This involves connecting your NTX wallet and integrating it with the Service Provider Dashboard (SPD) through the following steps:

Step 1: Connect your wallet to the SPD by clicking the "Connect Wallet" button at the top right corner of your browser. This action will initiate a secure connection between your wallet and the dashboard, allowing for seamless token transactions.

Step 2: Access the SPD on the service provider machine and navigate to the first page of the UI at localhost:9991. on your preferred browser.

Step 3: Provide the ML Model URL by pasting the link to your Python program that contains the machine learning code.

Some examples that you can use for testing it out:

• CPU - https://gitlab.com/nunet/ml-on-gpu/ml-on-cpu-service/-/raw/develop/examples/cpu-ml-test-scikit-learn.py

• GPU - https://gitlab.com/nunet/ml-on-gpu/ml-on-gpu-service/-/raw/develop/examples/pytorch/cifar-10_checkpointed.py

Step 4: Choose the type of compute resource you want to use for the job:

• Select the CPU radio button if you want to run the job on a CPU-only machine. Currently supported libraries for CPU jobs are TensorFlow, PyTorch, and scikit-learn.

• Select the GPU radio button if you want to run the job on a GPU machine. Henceforth, choose either the TensorFlow or PyTorch radio button to specify the library used in the program. For GPU jobs, only TensorFlow and PyTorch are currently supported.

Step 5: Specify the resource usage type: Low, Moderate, or High - depending upon the complexity of your job.

Step 6: If your job has any dependencies, enter their names by choosing the "+" symbol. If you are using our GPU based example code mentioned in step 3, note that you would need to specify a dependency named matplotlib. The CPU example does not require any dependencies.

Step 7: Enter the expected time for your job's completion and click 'Next' to proceed to the second page of the SPD's UI.

Step 8: When you connect your wallet, the NTX wallet address field would be auto-filled, based on the Cardano blockchain. Your wallet address is a unique identifier that enables you to send and receive NTX tokens within the Cardano network.

Step 9: Select the Cardano blockchain by clicking on the corresponding radio button. This ensures that the device management service communicates with the appropriate blockchain network to facilitate the exchange of NTX tokens for machine learning job requests.

Finally, click on "Submit" to confirm your wallet connection and complete the integration process. Once connected, your NTX tokens would be used to deploy the requested job by allocating it to a compute provider machine that matches the resource requirements. You can also monitor the progress of the machine learning job through the same dashboard.

Note: Currently, the WebSocket on the SPD does not have session management. This affects users because when they reload the page after making a deployment, they will not receive any response. This would be improvised in the near future. But it's recommended not to reload the page after deployment and wait for some time. For further troubleshooting if you do not receive any response after waiting for some time following a deployment, you can try the following:

1. Check the network connection: The first step is to ensure that the network connection is stable and working correctly. The user can try opening a different website to confirm that the issue is not with their internet connection.

2. Clear the browser cache: Sometimes, the browser cache can cause issues when loading web pages. Clearing the cache can help resolve this problem. The user can try clearing their browser cache and then reloading the page.

3. File a bug report: If the issue persists, the user should file a bug report about the problem. They can provide details about the issue and any error messages received, which will help in diagnosing and resolving the problem.

In general, it's always a good idea to document the steps taken and any error messages received when encountering issues with a web application. This information can be helpful when seeking support or troubleshooting the problem later on.

Understanding Issues on the Service Provider Dashboard

If you experience issues while using the dashboard, you can open the inspect console in your browser to get more information about the error. Here's how to do it:

1. Open the dashboard in your web browser.

2. Right-click anywhere on the page and select "Inspect" from the context menu. Alternatively, you can use the keyboard shortcut Ctrl + Shift + I on Windows/Linux or Cmd + Option + I on Mac to open the inspect console.

3. The inspect console will open in a separate window or panel. Look for the "Console" tab, which should be near the top of the panel.

4. If there are any errors, they will be displayed in the console with a red message.

When you hit the /run/request-service endpoint, you may encounter the following errors on the browser console:

• 400 Bad Request: This error occurs when the JSON payload received from the webapp cannot be parsed. This is unlikely to happen due to user error.

• 500 Internal Server Error: This error occurs when the DMS (Device Management Service) cannot find the libp2p public key. This is probably because the compute provider has not been onboarded properly.

• 400 Bad Request: This error occurs when the estimated price received from the webapp is more than expected. This is very unlikely to happen because the webapp guards against it.

• 404 Not Found: This error occurs when the DHT (Distributed Hash Table) does not have any peers with matching specs. After analyzing and filtering machines based on the constraints section on the payload, the DMS found no matched machine.

• 503 Service Unavailable: This error occurs when the DMS cannot connect to the Oracle for whatever reason.

• 500 Internal Server Error: This error occurs when a new service cannot run because the DMS is already running a service. Only one service is supported at the moment.

• 500 Internal Server Error: This error occurs when the DMS was not able to access the database.

• 200 OK: This response indicates success. It includes the compute_provider_addr, estimated_price, signature, and oracle_message.

What is the Device Management Service (DMS)?

A device management service or DMS is a program that helps users run various computational services, including machine learning (ML) jobs, on a compute provider machine, based on an NTX token request system on NuNet. In simple terms, it connects users who want to perform computational tasks to powerful CPU/GPU enabled computers that can handle these tasks. The purpose of the DMS is to connect users on NuNet, allow them to run any service (not only ML jobs) and be rewarded for it.

The NTX token is a digital cryptographic asset available on the Cardano and Ethereum blockchain as a smart contract. However, for the current use case of running machine learning jobs, only the Cardano blockchain is being used. Users request and allocate resources for computational jobs through a Service Provider Dashboard. Compute providers receive the NTX tokens based on the jobs through a Compute Provider Dashboard.

Please note that the dashboards are not components of NuNet's core architecture. Both these components have been developed to perform the current use case that is to run ML jobs on compute providers machines.

Here's a step-by-step explanation:

1. Users have computational services they want to run. These services often require a lot of computing power, which may not be available on their personal devices.

2. Compute provider machines are powerful computers designed to handle resource-intensive tasks like machine learning jobs.

3. The device management service acts as a bridge, connecting users with these compute provider machines.

4. Users specify resources and job requirements through a webapp interface, and request access to the compute provider machines by sending mNTX tokens. mNTX acts as a digital ticket, granting users access to the resources they need.

5. The device management service receives the job request after verifying the authenticity of the mNTX transaction through an Oracle.

6. Once received, the DMS allocates the necessary resources on the compute provider machine to run the user's job.

7. The user's job is executed on the provider's machine, and the results are sent back to the user.

In summary, a device management service simplifies the process of running machine learning jobs on powerful computers. Users can easily request access to these resources with NTX tokens, allowing them to complete their tasks efficiently and effectively.

How to Install the Device Management Service?

Before going through the installation process, let's take a quick look at the system requirements and other things to keep in mind.

Installing via Virtual Machines or Windows Subsystem (WSL) for Linux

When using a VM or WSL, using Ubuntu 20.04 is highly recommended.

Things to keep in mind for VMs

• Skip doing an unattended installation for the new Ubuntu VM as it might not add the user with administrative privileges.

• Enable Guest Additions when installing the VM (VirtualBox only).

• Always change the default NAT network setting to Bridged before booting the VM.

• Install Extension Pack if on VirtualBox (recommended)

• Install VMware Tools if on VMware (recommended)

• ML on GPU jobs on VMs are not supported

Things to keep in mind for WSLs

• Install WSL through the Windows Store.

• Install the Update KB5020030 (Windows 10 only)

• Install Ubuntu 20.04 through WSL

• Enable systemd on Ubuntu WSL

• ML Jobs begun on Linux cannot be resumed on WSL

• Make sure virtualization is enabled in the system BIOS

Though it is possible to run ML jobs on Windows machines with WSL, using Ubuntu 20.04 natively is highly recommended. The reason being our development is completely based around the Linux operating system. Also, the system requirements when using WSL would increase by at least around 25%.

If you are using a dual boot machine, make sure you use the wsl --shutdown command before shutting down Windows and running Linux for ML jobs. Also, ensure your Windows machine is not in a hibernated state when you reboot into Linux.

CPU-only machines

Minimum System requirements

We only require for you to specify CPU (MHz x no. of cores) and RAM but your system must meet at least the following set of requirements before you decide to onboard it:

• CPU - 2 GHz

• RAM - 4 GB

• Free Disk Space - 10 GB

• Internet Download/Upload Speed - 4 Mbps / 0.5 MBps

If the above CPU has 4 cores, your available CPU would be around 8000 MHz. So if you want to onboard half your CPU and RAM on NuNet, you can specify 4000 MHz CPU and 2000 MB RAM.

Recommended System requirements

• CPU - 3.5 GHz

• RAM - 8-16 GB

• Free Disk Space - 20 GB

• Internet Download/Upload Speed - 10 Mbps / 1.25 MBps

Abstract

The utilization of Graphics Processing Units (GPUs) has significantly enhanced the speed and efficiency of machine learning and deep learning applications. Docker containers, developed in a programming language called Go, are becoming more and more favored for guaranteeing the reproducibility and scalability of these applications. Nevertheless, Docker's built-in GPU compatibility is restricted to Nvidia GPUs, creating an obstacle to leveraging AMD and Intel GPUs. In this document, we introduce an innovative method, employing Go, to expand Docker's GPU compatibility to include AMD and Intel GPUs. This approach offers a vendor-neutral solution at the development level.

Introduction

The rise of machine learning and deep learning applications in a variety of fields such as computer vision, natural language processing, and bioinformatics, among others, has necessitated the use of high-performance computing resources. Graphics Processing Units (GPUs), initially designed to accelerate graphics rendering for gaming, have emerged as powerful accelerators for these data-intensive applications due to their massively parallel architectures.

In the realm of high-performance computing, reproducibility and portability of applications are essential. Docker, a platform that leverages containerization technology, provides a solution to these challenges. Docker containers encapsulate applications along with their dependencies, allowing them to run uniformly across different computational environments. Moreover, Docker's lightweight nature compared to traditional virtual machines makes it a preferable choice for deploying scalable and efficient applications.

However, while Docker has built-in support for Nvidia GPUs, it lacks the same native support for AMD and Intel GPUs. This discrepancy limits the full exploitation of the diverse GPU hardware landscape, creating vendor lock-in and potentially hindering the scalability and versatility of GPU-accelerated applications.

Docker is primarily developed in the Go programming language. Go, with its simplicity, strong concurrency model, and powerful standard library, provides a unique blend of high-level and low-level programming capabilities. This makes it an ideal candidate for developing solutions that require detailed system-level control, such as the interaction with GPUs, while maintaining an accessible and maintainable codebase.

This paper presents a novel approach for extending Docker's GPU support to AMD and Intel GPUs using the Go programming language. By addressing this problem at the development level, we aim to contribute to the open-source Docker project and pave the way for truly vendor-agnostic, scalable, and efficient GPU-accelerated applications. This development-level solution contrasts with the existing system-level workarounds and has the potential to eliminate unnecessary complexity for end-users, promoting more widespread adoption of AMD and Intel GPUs in high-performance computing.

Background & Related Work

Several works have addressed the challenges associated with GPU-accelerated computing in containerized environments. The most prominent solution is the `--gpus` option provided by Docker, which offers native support for Nvidia GPUs. This feature leverages the Nvidia Container Toolkit, an open-source project that provides a command-line interface for Docker to recognize Nvidia GPUs and allocate necessary resources to containers.

However, the current support is vendor-specific, and while it works seamlessly for Nvidia GPUs, it does not provide an out-of-the-box solution for other GPU vendors like AMD and Intel. Thus, the existing solutions focus on system-level workarounds to enable the use of AMD GPUs with Docker. AMD provides a deep learning stack that uses ROCm, a platform that allows deep learning frameworks to run on AMD GPUs. ROCm-enabled Linux kernel and the ROCk driver, along with other required kernel modules, need to be installed on the host that runs Docker containers.

Despite these advances, the present solutions do not address the issue at the development level within Docker. They require users to perform additional system-level configurations which increase the complexity and could potentially discourage users from adopting non-Nvidia GPUs for their applications. Furthermore, these solutions do not provide a unified, vendor-agnostic way to leverage GPUs in Docker, limiting the flexibility and scalability of GPU-accelerated applications in a diverse hardware landscape. This highlights the need for a development-level solution that is integrated within Docker itself, ensuring ease of use and true vendor-agnosticism.

Proposed Solution

Our innovative suggestion hinges on the application of a vendor-neutral technique to GPU backing within Docker at the coding stage. The end goal is to employ the Go programming language, Docker's foundational language, to help Docker organically detect and control not just Nvidia GPUs, but also AMD and Intel GPUs.

The initial part of the plan involves empowering Docker to attach the `/dev/dri` device within the container, ignoring vendor specificity. This can be achieved by altering the `devices` parameter within the `hostConfig` structure of Docker's `containerd` module. This change is made within Docker's Go language codebase, enabling Docker to detect and mount `/dev/dri` without the requirement of explicit bind mounting instructions during execution.

The second segment is to incorporate backing for AMD and Intel GPUs in the `resources` parameter of the `hostConfig` structure. At present, Docker acknowledges Nvidia GPUs via the `--gpus` flag, which internally changes the `resources` parameter. Our plan is to broaden this backing to AMD and Intel GPUs by allowing the `resources` parameter to identify these GPUs and allocate necessary resources to containers. This necessitates the enhancement of Docker's Go language codebase to incorporate the essential drivers and software stacks for these GPUs.

To encapsulate, the innovative proposal intends to present a consolidated and fluid method to utilize GPUs within Docker, regardless of the manufacturer. The prime benefit of this approach is its operation at the coding level, avoiding the necessity for intricate system-level configurations and offering a more user-centric experience. Moreover, it sets the stage for the inclusion of future GPUs from diverse manufacturers, boosting the scalability and flexibility of GPU-boosted applications in Docker.

Methodology

The adaptation of the projected answer demands alterations to the Go programming backbone of Docker, specifically pinpointing the `hostConfig` structure in the `containerd` module. Here is an elaborate guide on the amendments executed:

1. Annexing the `/dev/dri` apparatus: In the existing Docker formula, the `/dev/dri` the device must be directly linked to the container during operation. We tweaked the `devices` attribute in the `hostConfig` structure to incorporate `/dev/dri` by default through binding. This adjustment enables Docker to automatically append the `/dev/dri` apparatus inside the container, eradicating the need for explicit link creation commands.

2. Amplifying GPU attachment in the `resources` attribute: The `resources` attribute in the `hostConfig` structure is accountable for administering resources for Nvidia GPUs via the `--gpus` flag. We broadened this service to comprise support for AMD and Intel GPUs. The enactment needed enriching the Go programming foundation to incorporate the essential drivers and software piles for AMD and Intel GPUs. This transformation would permit Docker to acknowledge AMD and Intel GPUs and allocate requisite resources to containers using the `--gpus` flag.

The aforementioned adaptations were implemented in the Go coding language, adhering to the axioms and ideal practices of the language. Go's potent static typing and emphasis on directness and simplicity were notably advantageous in preserving the legibility and sustainability of the Docker programming base.

Trials of the projected answer were successfully conducted on hardware with AMD GPUs (/dev/dri with /dev/kfd) to validate its precision and potency. The trials involved operating GPU-accelerated software within Docker containers and authenticating their operation and resource consumption through NuNet's Device Management Service - https://gitlab.com/nunet/device-management-service. The findings indicate that the projected answer can successfully empower Docker to support AMD and Intel GPUs in a fluent and user-friendly mode.

In conclusion, the projected answer was enacted and tried successfully in Docker's Go programming base. The adaptation particulars corroborate the viability of the answer and its capability to revolutionize the mode Docker accommodates GPUs from assorted manufacturers.

Reflection and Forward Directions

The proposed methodology has effectively resolved the original challenge of delivering an intuitive, hassle-free experience for AMD and Intel GPU users interacting with Docker. By tweaking the Docker codebase, which is written in Go, Docker now has the capability to independently recognize and employ AMD and Intel GPUs, eliminating the necessity for explicit bind mounts or personalized scripts.

The benefits of this methodology include:

1. Simplicity: Users are exempted from the need to manually bind mount the GPU device or write personalized scripts for the container set-up.

2. Interoperability: The methodology is supplier-neutral and is compatible with Nvidia, AMD, and Intel GPUs, thereby enhancing Docker container compatibility across diverse systems.

3. Expandability: The methodology enables superior hardware utilization in broad, multi-GPU contexts, such as those in high-performance computing clusters.

Nonetheless, there remain opportunities for further enhancement and research:

1. Expanded Validation: While preliminary trials have yielded encouraging outcomes, exhaustive testing on diverse hardware and software setups is necessary to confirm resilience and compatibility.

2. Efficiency Enhancement: At present, the methodology prioritizes functionality over optimal performance. Prospective efforts could explore strategies to boost the efficiency of GPU-boosted applications operating within Docker containers.

3. Inclusion of Additional Devices: The current methodology concentrates on GPUs, but the approach could be broadened to incorporate other hardware devices that could profit from a similar approach, such as FPGAs or TPUs.

4. Synchronization with Management Tools: A vital future trajectory would be to amalgamate the devised methodology with container management tools like Kubernetes, boosting the scalability and ease of management of GPU-boosted workloads in distributed systems.

This study has paved the way for more advancements and investigations. By enhancing Docker's compatibility with AMD and Intel GPUs, we have made significant progress in making GPU-boosted computing more attainable and efficient for a broader set of users and applications. Anticipated future endeavors in this field hold the potential for more upgrades and breakthroughs.

Conclusion

The adoption of Docker container technology in machine learning and data science operations has been progressively prevalent, largely due to its reproducibility, portability, and scalability attributes. However, an obstacle arises from Docker's lack of broad-ranging GPU support, particularly problematic for users utilizing GPUs other than Nvidia's. In order to rectify this, we introduced a novel approach that adapts Docker's Go foundation to automatically detect and harness AMD and Intel GPUs, thereby eliminating the necessity for explicit bind mounts or bespoke scripts.

This innovative approach not only resolves the immediate predicament but also propels further investigation and progress in the realm of container-centric computing. It forms a solid foundation for more efficient hardware usage in expansive, multi-GPU environments, akin to those encountered in high-performance computing networks. Additionally, it encourages subsequent efforts towards performance refinement, aid for varied hardware entities, and amalgamation with container orchestration tools.

In summary, our scholarly pursuits signify a substantial stride in democratizing GPU-intensified computing, making it more approachable and effective for an expanded spectrum of users and use-cases. By augmenting Docker's compatibility with AMD and Intel GPUs, we have broadened the reach of container-based computing, thereby nurturing a more varied and inclusive computational research landscape.

https://gitlab.com/nunet/ml-on-gpu/ml-on-gpu-service/-/raw/develop/examples/pytorch/cifar-10.py

1. Check for GPU availability: The code checks if a GPU is available for faster computation. If it is, the code will utilize the GPU.

2. Load and preprocess the images: The code retrieves the CIFAR-10 dataset and preprocesses the images, preparing them for the machine learning process.

3. Display random images*: The code contains a function to display a few random images from the dataset that will be used for training.

4. Define a Convolutional Neural Network (CNN) architecture: The code creates a CNN architecture to guide the machine in learning how to recognize images.

5. Prepare the machine for training: The code configures the machine to follow the CNN architecture and determines the approach to learning from mistakes.

6. Train the machine: The code trains the machine using the images for 100 iterations (epochs). It keeps track of the machine's performance during training.

7. Test the trained machine: After training, the code evaluates how well the machine can identify images it has not seen before, using a test set of images.

8. Evaluate the machine's performance: The code calculates the overall accuracy of the machine in identifying the test images, as well as the accuracy for each category of images in the dataset.

However, this code does not include a checkpointing system to save the machine's learning progress. If training is interrupted, the process will have to start from the beginning.

Teaching a Machine to Recognize Images with PyTorch and the CIFAR-10 Image Set (Checkpointed)

This code is a modified version of the previous one. The main changes are related to adding functionality for checkpointing and resuming training from a saved state.

4. The generated response is decoded, and any special tokens are removed before it's returned.

5. Using Gradio, a simple chat window is created for users to input text and see the chatbot's response.

6. Finally, the chat window is launched, allowing users to interact with the T5 model and see its responses.

This code helps you set up a simple and interactive chatbot, making it easy to use the T5 model to generate responses for user inputs.

Simple Chatbot Using GPT2 and Gradio

This is a similar chatbot like the previous ones above.

https://gitlab.com/nunet/ml-on-gpu/ml-on-gpu-service/-/raw/develop/examples/pytorch/gpt2-large_chatbot.py

Here's what it does:

• This code creates a chatbot using a smart model called GPT-2 and a tool named Gradio that makes it easy to talk to the chatbot.

• The code uses tools from the Transformers library to load the GPT-2 model and set it up.

• A special token is added to help the model understand when a message starts and ends.

• The code has a chatbot function that changes your message into a form the model understands, makes the model think of a reply, and then changes the reply back to normal text.

• A simple Gradio chatbot interface is made, so you can ask questions and get answers from the chatbot.

Comparing this code with the previous ones, this one uses a model named GPT-2 instead of another model called T5. The way the model is loaded is a little different, but the overall idea of creating a chatbot using Gradio remains the same.

Train and Generate Text with PaLM Model using PyTorch (Not Checkpointed)

This code is a PyTorch implementation of the PaLM model for text generation. The code is written by Phil Wang and licensed under MIT license.

https://gitlab.com/nunet/ml-on-gpu/ml-on-gpu-service/-/raw/develop/examples/pytorch/palm-rlhf.py

It trains and generates text by following the steps:

• The code uses PyTorch and Palm-rlhf-pytorch library to implement PaLM model for training and inference.

• The enwik8 dataset (a subset of Wikipedia), is used for training the model, which is downloaded using curl command and saved locally in the data directory.

• A TextSamplerDataset is defined to create train and validation datasets from the enwik8 dataset.

• A PaLM model is instantiated with hyperparameters and moved to the device (GPU) using accelerator.

• An optimizer is created to optimize the PaLM model using Adam optimization algorithm

• The training is done for a fixed number of batches, where the loss is calculated using PaLM model on training dataset, the gradients are accumulated and backpropagated, and the parameters are updated using the optimizer.

• Validation loss is also calculated every few batches to check the performance of the model on the validation dataset.

• The model is also used for generating text after every few batches.

• After training, the model is used for inference by getting user input, generating text using the trained PaLM model, and printing the output.

Summarizing, this code trains a neural network using the PaLM architecture to generate text similar to a given dataset. The dataset used here is enwik8, which is an 100 MB dump of the English Wikipedia. The code defines a PaLM model and uses PyTorch DataLoader to feed the data to the model. It uses an accelerator library to distribute the computation across available devices, such as GPUs. Finally, it allows the user to test the generated model by inputting a sentence, and the model responds with a predicted output.

Train and Generate Text with PaLM Model using PyTorch (Checkpointed)

This code is a language model, PaLM, trained on enwik8 dataset. It trains the model on GPU by using PyTorch's DataParallel library, allowing distributed computing on GPUs.

https://gitlab.com/nunet/ml-on-gpu/ml-on-gpu-service/-/raw/develop/examples/pytorch/palm-rlhf_checkpointed.py

Revisiting the points with checkpointing:

• This code uses PyTorch's PaLM model and Accelerator library for distributed computing on GPUs.

• The code downloads the enwik8 dataset and divides it into training and validation sets.

• The code uses TextSamplerDataset to load data into PyTorch DataLoader, which is then used for training.

• It uses the Adam optimizer for training and also employs learning rate scheduler.

• The code implements checkpointing to save model weights and optimizer states at a defined interval and allows resuming from the last checkpoint.

• The code trains the model for a defined number of batches and validates after a defined interval.

• It generates a sample text after a defined interval and also provides an option for the user to enter a prompt for generating text.

• The training and generation logs are displayed using the tqdm library.

Summarizing, this code trains a PaLM language model on the enwik8 dataset using PyTorch and Accelerator libraries. It implements checkpointing to resume training from the last checkpoint and uses PyTorch's DataParallel library for distributed computing on GPUs. The model is trained for a defined number of batches and generates sample text after a defined interval. The user can also enter a prompt for generating text. The training and generation logs are displayed using the tqdm library.

Fashion MNIST Image Classification using TensorFlow and Keras (Checkpointed)

This code trains a neural network classifier on the Fashion-MNIST dataset and uses checkpointing to save and restore the model weights. Checkpointing allows training to be interrupted and resumed without losing progress. The checkpoint is saved after every epoch, and the number of epochs completed before the training was interrupted is recorded in a text file.

Building and Evaluating a Decision Tree Classifier on the Iris Dataset with scikit-learn (CPU-only)

The Iris dataset is a classic example in the field of machine learning used for classification tasks. In this code, we will use the scikit-learn CPU-only library to build a Decision Tree Classifier on the Iris dataset. The code will train the classifier on 80% of the data and test it on the remaining 20% of the data. Finally, the code will evaluate the model's performance using accuracy, classification report, and confusion matrix.

https://gitlab.com/nunet/ml-on-gpu/ml-on-cpu-service/-/raw/develop/examples/cpu-ml-test-scikit-learn.py

What it does:

• Load necessary libraries such as numpy, Scikit-learn's load_iris, train_test_split, DecisionTreeClassifier, accuracy_score, classification_report, and confusion_matrix.

• Load the Iris dataset and separate input features (X) and output labels (y).

• Split the dataset into train and test sets (80% training, 20% testing) using train_test_split.

• Create a Decision Tree Classifier and fit it to the training data using DecisionTreeClassifier and fit methods.

• Make predictions on the test set using predict method.

• Evaluate the model's performance using accuracy_score, classification_report, and confusion_matrix methods.

• Print the accuracy of the model on the test set.

• Print the classification report, which shows precision, recall, f1-score, and support for each class.

• Print the confusion matrix, which shows the number of true positives, false positives, true negatives, and false negatives for each class.

So in this code, we used the CPU-only Scikit-learn library to build a Decision Tree Classifier on the Iris dataset. The code split the dataset into 80% training and 20% testing sets, trained the classifier on the training set, and tested it on the test set. Finally, we evaluated the model's performance using accuracy, classification report, and confusion matrix. The accuracy of the model on the test set was printed, and the classification report and confusion matrix were shown to provide additional insights into the model's performance.

To Understand ML Job Error Handling on NuNet

This ML code snippet will give an error. So it can be used for testing the workflow to understand how we handle failed jobs:

https://gitlab.com/-/snippets/2523096/raw/main/tensor-shape-pytorch-error.py

When you try to run this program, you will receive the following message:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
RuntimeError: The size of tensor a (5) must match the size of tensor b (3) at non-singleton dimension 0

This error occurs because we're trying to perform an operation (in this case, addition) on two tensors that don't have the same shape. In PyTorch, element-wise operations require the tensors to have the same shape or be broadcastable to a common shape. In this case, the shapes (5, 2) and (3, 2) are not compatible because the sizes along the first dimension do not match, and they can't be broadcasted to a common shape.

There are of course numerous other types of errors for other ML/Computational code that you might encounter while working with PyTorch (or any ML/Computational library for that matter), including but not limited to:

1. TypeError: This could happen when you pass arguments of the wrong type to a function. For example, passing a list where a tensor is expected.

2. ValueError: This could occur when you pass arguments of the correct type but incorrect value to a function. For example, passing negative integers to a function that expects positive integers.

3. IndexError: You may encounter this when you try to index a tensor using an invalid index.

4. MemoryError: This occurs when the system runs out of memory, often when trying to allocate very large tensors.

5. RuntimeError: This is a catch-all for various kinds of errors that can occur during execution. The tensor shape mismatch error we discussed earlier is a type of RuntimeError.

Here's an example of a code snippet that will give a TypeError:

import torch

# Create a list
list1 = [1, 2, 3, 4, 5]

# Try to perform a tensor operation on the list
result = torch.tanh(list1)

When you run this program, you'll receive a TypeError with the following message:

tanh(): argument 'input' (position 1) must be Tensor, not list

The error handling approach varies depending on the type of error. For this TypeError, you can handle it by converting the list to a tensor before performing the operation:

import torch

# Create a list
list1 = [1, 2, 3, 4, 5]

# Convert the list to a tensor
tensor1 = torch.tensor(list1)

# Perform the tensor operation
result = torch.tanh(tensor1)

From an ML developer's or researcher's perspective, it's always good practice to anticipate potential errors and handle them gracefully in the ML/Computational code.

Deploying any GPU-based Python Project on NuNet

This tutorial will guide you through the process of deploying any GPU-based Python project on NuNet, which is our base platform that allows running machine learning or computational jobs. We will use a Python file URL and pip dependencies through the dashboard interface.

Please note that this tutorial assumes that your Python project is structured as a command-line-interface (CLI) based project with a requirements.txt file for specifying dependencies.

Prerequisites

1. Access to the service provider dashboard interface.

2. A GPU-based Python project hosted on a platform like GitLab or GitHub, with the main script and requirements.txt file accessible via URLs.

Steps

1. Prepare Your Python Script: Modify your main Python script to programmatically install dependencies from the requirements.txt file. The following sample code demonstrates how you might do this:

   Copy

   import subprocess
   import os
   import urllib.request
   
   # Define the URL of your requirements.txt file
   requirements_url = 'https://raw.githubusercontent.com/yourusername/yourrepo/master/requirements.txt'
   
   # Download the requirements.txt file
   urllib.request.urlretrieve(requirements_url, 'requirements.txt')
   
   # Use pip to install the requirements
   subprocess.check_call(["python", '-m', 'pip', 'install', '-r', 'requirements.txt'])
   
   # Rest of your code follows
   
   # Define the home directory assuming your code saves all checkpoints/models/datasets in this location
   home_dir = os.path.expanduser('~')
   
   # Define the tar file name
   tar_file = 'archive.tar.gz'
   
   # Create a tar file of the home directory
   subprocess.check_call(['tar', '-czf', tar_file, '-C', home_dir, '.'])
   
   # Define the URL of your repository
   repo_url = 'https://oauth2:{token}@gitlab.com/yourusername/yourrepo.git'.format(token=os.getenv('GITLAB_TOKEN'))
   
   # Clone the repository
   subprocess.check_call(['git', 'clone', repo_url])
   
   # Move the tar file into the repository
   subprocess.check_call(['mv', tar_file, 'yourrepo'])
   
   # Change the current directory to the repository
   os.chdir('yourrepo')
   
   # Add the tar file to the repository
   subprocess.check_call(['git', 'add', tar_file])
   
   # Commit the changes
   subprocess.check_call(['git', 'commit', '-m', 'Add tar file'])
   
   # Push the changes
   subprocess.check_call(['git', 'push'])
   

This script will:

1. Download and install the dependencies from the requirements.txt file.

2. Execute your main script's logic (which you would add after the "# Rest of your code follows" comment).

3. Tar the entire contents of the /home/$LOGNAME directory. (assuming your code saves all checkpoints/models/dataset at this location)

4. Push this tar file to the specified GitLab or GitHub repository.

Please replace the placeholders 'https://raw.githubusercontent.com/yourusername/yourrepo/master/requirements.txt' and 'https://oauth2:{token}@gitlab.com/yourusername/yourrepo.git' with the actual URLs of your requirements.txt file and GitLab or GitHub repository, respectively.

Remember that {token} should be replaced with your Personal Access Token. This script expects the Personal Access Token to be stored in an environment variable named GITLAB_TOKEN. You can create this token temporarily and set it to expire around the same time your job is presumed to be finished.

1. Navigate to the NuNet Dashboard: Launch the service provider dashboard via localhost:9991 on your preferred browser and navigate to the dashboard interface.

2. Enter the Python File URL: In the appropriate field, enter the URL of your modified Python script.

3. Specify the Dependencies: In the dependencies field, you might need to specify any dependencies that your script needs beyond those specified in the requirements.txt file. If all dependencies are included in the requirements.txt file, this field can be left blank.

4. Fill up the remaining relevant fields: Apart from the above two fields, also fill up the other fields as described in the service provider dashboard usage guidelines.

5. Execute the Job: Click the appropriate button to execute the job. The NuNet platform will download your script, install the necessary dependencies, and run the script.

Considerations

• Complex Dependencies: If your project requires dependencies that cannot be installed with pip, you may need to find a workaround, such as including the installation process within your Python script.

• Data Dependencies: If your project requires access to specific data files, you may need to modify your Python script to download or access these files.

• Security: Only use this approach with trusted scripts and dependencies, as the platform will execute your script and install the specified packages without further confirmation.

• Long-Running Processes: If your project initiates long-running processes, you'll need to manage and monitor these within the constraints of the NuNet platform.

Following these steps should allow you to deploy and run a wide variety of GPU-based Python projects on the NuNet platform. While this method may not work for every project without some adjustments, it provides a flexible starting point for deploying projects on NuNet.
