How to install additional Python packages¶
To install additional packages for use in the container, you will need to get an interactive session on a GPU node.
srun --time=01:00:00 --nodes=1 --cpus-per-task=4 --partition=gpu --gres=gpu:1 --pty /usr/bin/bash
Load the version of the ml-gpu module you want to use. For example:
module load ml-gpu/20220928
Next, create a directory to install the packages to. This should be within your group's /work directory, and specific to the version of the ml-gpu container that you're using.
ml-gpu python -m venv --system-site-packages /work/LAS/your-lab/mlgpuvenv-20220928
Now you can install the additional packages with pip.
ml-gpu /work/LAS/your-lab/mlgpuvenv-20220928/bin/pip3 install somepackage
To confirm the packages are installed:
ml-gpu /work/LAS/your-lab/mlgpuvenv-20220928/bin/pip3 freeze | grep somepackage
Your package is now installed.
To use these additional packages in your batch scripts, load the ml-gpu module, then invoke python like this:
ml-gpu /work/LAS/your-lab/mlgpuvenv-20220928/bin/python your_script.py
Be sure to replace the path with the actual location you installed the packages.
PyTorch is already included in the container. If you decide to install a different version, it likely will not work with newer GPU cards unless you follow the instructions on the PyTorch website, and adapt them to install it to your virtual environment. Also be sure to use the CUDA version that's listed on the pre-installed software page. E.g.
To install this to your virtual environment, you would do the following:
ml-gpu /work/LAS/your-lab/mlgpuvenv-20220928/bin/pip3 install --pre torch torchvision torchaudio --extra-index-url https://download.pytorch.org/whl/nightly/cu117
