Getting Started with Docker

This document walks you through how to set up TT-XLA using a Docker image. There are two other available options for getting started:

• Installing a Wheel - if you do not want to use Docker, and prefer to use a virtual environment by itself instead, use this method.
• Building from Source - if you plan to develop TT-XLA further, you must build from source, and should use this method.

The following topics are covered:

• Configuring Hardware
• Setting up the Docker Container
• Running Models in Docker
• Where to Go Next

Configuring Hardware

Before setup can happen, you must configure your hardware. You can skip this section if you already completed the configuration steps. Otherwise, this section of the walkthrough shows you how to do a quick setup using TT-Installer.

1. Configure your hardware with TT-Installer using the Quick Installation section here.

2. Reboot your machine.

3. Please ensure that after you run this script, after you complete reboot, you activate the virtual environment it sets up - source ~/.tenstorrent-venv/bin/activate.

4. When your environment is running, to check that everything is configured, type the following:

tt-smi

You should see the Tenstorrent System Management Interface. It allows you to view real-time stats, diagnostics, and health info about your Tenstorrent device.

Setting up the Docker Container

This section walks through the installation steps for using a Docker container for your project.

To install, do the following:

1. Install Docker if you do not already have it:

sudo apt update
sudo apt install docker.io -y
sudo systemctl start docker
sudo systemctl enable docker

2. Test that Docker is installed:

docker --version

3. Add your user to the Docker group:

sudo usermod -aG docker $USER
newgrp docker

4. Run the Docker container:

docker run -it --rm \
  --device /dev/tenstorrent \
  -v /dev/hugepages-1G:/dev/hugepages-1G \
  ghcr.io/tenstorrent/tt-forge/tt-xla-slim:latest

5. If you want to check that it is running, open a new tab with the Same Command option and run the following:

docker ps

Running Models in Docker

This section shows you how to run a model using Docker. The provided example is from the TT-Forge repo. Do the following:

1. Inside your running Docker container, clone the TT-Forge repo:

git clone https://github.com/tenstorrent/tt-forge.git

2. Set the path for Python:

export PYTHONPATH=/tt-forge:$PYTHONPATH

3. Navigate into TT-Forge and run the following command:

git submodule update --init --recursive

4. Navigate back out of the TT-Forge directory.

5. Run a model. Similar to gpt2, this model predicts what the next word in a sentence is likely to be. For this model, the demo.py for opt_125m is used. The requirements.txt file shows that you need to install flax and transformers:

pip install flax transformers

7. After completing installation, run the following:

python tt-forge/demos/tt-xla/opt_125m/demo.py

If all goes well, you should get an example prompt saying 'The capital of France is.' The prediction for the next term is listed, along with the probability it will occur. This is followed by a table of other likely choices.

Where to Go Next

Now that you have set up TT-XLA, you can compile and run your own models, or try some of the other demos. You can find TT-XLA demos in the TT-Forge directory.
