You can also update the conda environment file to modify the behavior under a key env2ini:

dependencies:
  # for conda plugins
  - conda

  # for publishing to pypi and conda
  - twine
  - anaconda-client

# env2ini specifications
env2ini:
  # packages to ignore (not moved to settings.ini)
  ignore:
    - pip
    - python
    - twine
    - anaconda-client
    - notebook
    - ipykernel
    - ipywidgets
    - jupyter_contrib_nbextensions
  # mapping of the name of the package on conda to that of its name in pypi
  aliases:
    torch: pytorch
    lightning: pytorch-lightning

Note: doing so will yield a warning which looks like this:

EnvironmentSectionNotValid: The following section on 'path/to/file/env.yml' is invalid and will be ignored:
 - env2ini

Legacy

the deprecated original script env_to_ini.py

envtoini.py

This script is not a part of the package. It is however provided to show where the project came from. It was designed so that if your env.yml (or env.mac.yml) file changes you can automatically update the depedencies of the env2ini package (under settings.ini) to match.

$ python env_to_ini.py

# show packages that didnt change
$ python env_to_ini.py  --unchanged
