Software

The user-nodes are equipped with a normal developer packages. If you feel that something is missing, please submit a ticket via the Portal

Virtual Environment Setup

In general, our system is compatible with the documentation from Cerebras which should be followed. In this early phase, a few small tweaks are required:

Use Cerebras ModelZoo 2.5.0 for compatibility to the Cerebras machine's installed software-sdk version For completness both the clone and checkout are included below:

git clone https://github.com/Cerebras/modelzoo.git ./modelzoo
cd modelzoo
git checkout Release_2.5.0

Running codes

Run as per the normal Cerebras documentation. It is advisable to run codes inside a tmux session so you can return to them without having to leave SSH sessions active whilst jobs run.

You may see some warnings about mount paths, e.g. The following editable packages are not in a volume accessible to the cluster, however these can be safely ignored.

Example training Llama4b on a single CS3

With a suitably configured venv as above, and the modelzoo checked out:

  • Navigate to <your modelzoo checkout>/src/cerebras/modelzoo/models/nlp/llama/configs/ and copy the file params_llama3p1_8b_msl_128k.yaml to params_example.yaml
  • Adjust the copied params_example.yaml config to reduce the max_steps field to 50
  • Adjust the copied params_example.yaml config to change the data_dir field to /home/y26/shared/rpj_1t_100k_llama3p1_msl8k_train
  • Navigate to <your modelzoo checkout>/src/cerebras/modelzoo/models/nlp/llama/
  • Run using cszoo fit --num_csx=1 configs/params_example.yaml --mount_dirs /home/<your_project>/<your_project>/<your_username>/ /home/y26/shared/ --python_paths ~/modelzoo/src/ --model_dir llama4b_u3

Example: Training Vision Transformer on ImageNet Mini

This tutorial will train a toy Visual transformer on a collection of captioned data, the produced model being able to input and image and output a caption.

We make use of the imagenet-mini dataset, a subset of 1000 samples from the ImageNet dataset.

  1. Set up your virtual environment as described above

  2. Create a space in which the model will be stored

    mkdir -p ~/imagenet_tutorial
cd ~/imagenet_tutorial

  3. Copy the training configuration:

    cp /home/y26/shared/params_vit_imagenet.yaml ~/imagenet_tutorial

  4. Run the training job:

    cszoo fit params_vit_imagenet.yaml --num_csx=1 \
  --mount_dirs /home/y26/shared/ /home/<your_project>/<your_project>/<your_username>/ \
  --python_paths /home/<your_project>/<your_project>/<your_username>/modelzoo/src
