FOD

The purpose of fod is to experiment with automatic environment checkpointing. It will sit on top of pixi, using it as a backend to manage environments.

Dev env

To setup your dev env, create a conda env

$ conda env create -f environment.yml 

$ conda activate fod-dev

# install fod with pip in editable mode
$ python -m pip install -e .

Add the fod bin directory to path

$ export PATH="$PWD/fod/bin:$PATH"

Make sure to also install pixi

Try it out

Use the pixi environment provided in the demo-assets/pixi-py directory.

$ cd demo-assets/pixi-py

# install the env
$ fod install

# try installing some new packages
$ fod add filelock
$ fod add scipy

# list available checkpoints
$ fod checkpoint list
                         Checkpoints
