## ENV CREATION - steps to reproduce:
# mamba env remove -n bnb
# mamba create -y -n bnb python=3.8 # creating an empty env bypasses conda
# # and leads to much faster env resolution in the next step https://github.com/mamba-org/mamba/issues/633#issuecomment-812272143
# mamba env update -n bnb -f environment.yml
# mamba activate bnb

## PIP dependencies (install *after* ENV CREATION):
# pip install --no-cache-dir --no-deps lion_pytorch triton peft
## NOTE: conda peft is not up to date, so we install from pip
# cd pip install -e .  ## installs bitsandbytes as editable development install from within repo root dir

## ENV UPDATE:
# # add new packages to environment.yml, then:
# mamba env update -n bnb -f environment.yml
