Usage

See action.yml

Basic:

The basic usage makes the conda python version the default python ($ conda activate base).

steps:
  - uses: actions/checkout@v3
  - uses: s-weigand/setup-conda@v1
  - run: conda --version
  - run: which python

If you don't want to change the python version which is used (e.g. you just need to install a none python package), you can use activate-conda: false.

steps:
  - uses: actions/checkout@v3
  - name: Set up Python 3.8
    uses: actions/setup-python@v4
    with:
      python-version: 3.8
  - uses: s-weigand/setup-conda@v1
    with:
      activate-conda: false
  - run: conda --version
  - run: which python
