Environment Setup

📘
Please contact us to gain access to the Self-Hosted GPU Runner feature.

Prerequisites

Root access (e.g. sudo) is required in certain steps such as configuring microk8s when installing the runner, please ensure that you have the necessary permissions. Once the runner has been set up, root access is no longer necessary.

Supported Systems

Any operating system that can run python, microk8s, and can install NVIDIA drivers.
- Recommended OS: Ubuntu ≥ 20.04 [tested!]
At least 1 NVIDIA GPU present in the target system with compatible NVIDIA drivers installed (≥ 515, ≤ 535).

Packages

Python ≥ 3.8

sudo apt-get install -y python3.8 python3-pip

NVIDIA Drivers ≥ 515, ≤ 535 - check out the installation guide.

sudo ubuntu-drivers install

NVIDIA Container Toolkit - check out the installation guide.

curl -fsSL https://nvidia.github.io/libnvidia-container/gpgkey | sudo gpg --dearmor -o /usr/share/keyrings/nvidia-container-toolkit-keyring.gpg \
  && curl -s -L https://nvidia.github.io/libnvidia-container/stable/deb/nvidia-container-toolkit.list | \
    sed 's#deb https://#deb [signed-by=/usr/share/keyrings/nvidia-container-toolkit-keyring.gpg] https://#g' | \
    sudo tee /etc/apt/sources.list.d/nvidia-container-toolkit.list

sudo apt-get update

sudo apt-get install -y nvidia-container-toolkit

Snap - check out the installation guide.
snap is a convenient package manager used to install microk8s. If you are using another method to install microk8s, or already have microk8s installed, you can skip installing snap.

sudo apt-get install snapd

MicroK8s - check out the installation guide.
microk8s is used by the Runner to handle the model training and infrastructure.

sudo snap install microk8s --classic --channel=1.30

# configure microk8s permissions
sudo usermod -a -G microk8s $USER
mkdir -p ~/.kube
chmod 0700 ~/.kube
newgrp microk8s

# enable microk8s add-ons
microk8s enable dns
microk8s enable hostpath-storage
microk8s enable nvidia
microk8s enable registry

Authentication

🚧
Please ensure that you retrieve the Workspace Key in the Settings page of the Workspace Dashboard, and not the Project Key that is specific to each project in your workspace.

To authenticate your Custom Runner, click on the ⚙️ Settings button at the top right of your Workspace Dashboard, and navigate to the Key Manager tab. You will need to generate a Secret Key, and save both the Secret Key and Workspace ID for the runner initialization. The Secret Key will only be be shown once - you will need to regenerate this key if you navigate away from the page and have not saved it.

Install Runner

Install Datature Python SDK and CLI:
```
pip install datature
```
Run the following command to setup and initialize your Runner:
```
datature runner install
```
After the prerequisite packages have been verified present on your system, you will be prompted for the name of your Runner, your workspace secret key, and workspace ID. The workspace secret key and workspace ID can be obtained from the Authentication section above.
```
? Please enter the name for your Runner: my-custom-runner
? Please enter your Workspace Secret Key: ****************************************************************
? Please enter your workspace ID: 54c6eea142f045069e4bc04f73c7bd76
```
Once the initialization has completed, you should see this message:
```
Success: Runner installed and initialized.
Return to your Nexus workspace to start a model training: https://nexus.datature.io/workspace/54c6eea142f045069e4bc04f73c7bd76
```
You can now head back to Nexus and set up a training run to check that you can select your Custom Runner.
In the case of any errors faced, check out our Error Handling guide for solutions to common issues, or contact us for support.

Manage Your Runner

To learn more about what functions you can use to manage your runner, or how to utilize your newly-set up runner to train a model on Nexus, check out the following pages:
