Better PyPI interoperability for the conda ecosystem.

The conda-pypi plugin improves conda's integration with the PyPI ecosystem. The most important feature is the conda-pypi channel, hosted by Anaconda, which makes pure Python pacakges from PyPi available to users natively through conda install.

conda-pypi is available in conda 26.5 or later. To update:

conda install --name base "conda>=26.5"

To opt in, enable the Rattler solver and add the conda-pypi channel:

conda config --set solver rattler
conda config --append channels conda-pypi

During the beta, the conda-pypi channel might not appear in the Anaconda.org web UI and some commands such as conda search can fail because they request classic repodata.json metadata. Use conda install or conda create --dry-run to check whether the solver can use the channel.

After configuring, you can use PyPI packages alongside conda packages in your normal conda workflows, without needing to convert PyPI's wheel files to conda files.

conda-pypi includes more advanced subcommand controls for working with PyPI packages. These options are recommended for users who want to experiment with conda and wheels and work with cutting-edge plugin features.

You can use the following commands with the conda pypi subcommand to do more with the conda-pypi plugin:

• conda pypi install: Converts PyPI packages to .conda format for safer installation.
• conda pypi install -e .: Converts a path to an editable .conda format package.
• conda pypi convert: Convert PyPI packages to .conda format without installing them.
• conda install from wheel channels (experimental): channels can serve pure Python wheels directly in repodata.json.
• A warning when running conda create or conda install with pip in the environment.

Mixing conda and PyPI is often discouraged in the conda ecosystem. There are only a handful patterns that are safe to run. This tool aims to provide a safer way of keeping your conda environments functional while mixing it with PyPI dependencies. Refer to the documentation for more details.

• This project now incorporates conda-pupa by Daniel Holth, which provides the core PyPI-to-conda conversion functionality.
• The conda-pypi platypus logo is by James Turner.
