conda_poetry_liaison

Do not use another package manager in a conda environment.

Many are given this advice, but we do this anyway. We want our conda-only packages with the awesome features of poetry. conda_poetry_liaison is a small collection of scripts to make this as painless and reproducible as possible.

Scripts

cpl-deps

The primary issue of using other package managers like pip and poetry inside a conda environment is that they will not communicate. If you install a package with conda, then install a different one in pip, conda will have no idea what has changed. So once you start using pip or poetry, you cannot use conda to install a package in that same environment.

This script will add all Python packages installed in the conda environment into the pyproject.toml file. Now, poetry will be aware of these packages during dependency solving.

usage: cpl-deps [-h] [--env_name [ENV_NAME]] [--env_path [ENV_PATH]] [--group_name [GROUP_NAME]] [toml_path]

Notify poetry of conda Python packages

positional arguments:
  toml_path             Path to TOML file

options:
  -h, --help            show this help message and exit
  --env_name [ENV_NAME]
                        Name of conda environment to probe
  --env_path [ENV_PATH]
                        Path of conda environment to probe
  --group_name [GROUP_NAME]
                        Name of poetry dependency group

cpl-clean

There seems to be a remnant of direct_url.json files from conda package installations that break poetry (as discussed here). One workaround is to delete these files in the conda environment directory before using poetry.

usage: cpl-clean [-h] [env_path]

Notify poetry of conda Python packages

positional arguments:
  env_path    Path of conda environment to clean

options:
  -h, --help  show this help message and exit

Development

Install poetry if you do not have it.

make poetry-download

If you already have poetry installed, make sure you have poetry-dynamic-versioning.

poetry self add "poetry-dynamic-versioning[plugin]"

Install the package.

make install

Install all pre-commits.

make pre-commit-install
