Compute Studio runs each project in its own Docker container. Miniconda3 is used as the base image. This means that conda is installed by default. Thus, all packages available through the conda package manager can easily be installed. Include installation instructions in your email to Hank, and he will add them to the project's Dockerfile. If you are inclined, you will have access to this Dockerfile and will be able to build the Docker image and experiment with it. The installation instructions for the matchups project are simply a bash script:
conda install pandas pyarrow
pip install pybaseball matchups
