Hey all! Here is a place for us to discuss PyPI and conda interoperability

Cool!

Ooh! I didn’t know there was a push to improve that!

#

Awesome!

#

I think with the coming variants, there’s somce complexity on the horizon that needs to be handled

#

not to speak of the existing complexity that isn’t handled yet i.e. solving PyPI and conda packages together: only Pixi does that to this day AFAIK

Hey @vernal kettle, one of the things that initiated the discussion at PyCon is conda got a new feature called conda-pypi, that offers a channel with all the Pure Python wheels on PyPI and allows conda to install them natively in a single solve: https://docs.conda.io/projects/conda/en/stable/new-features.html

hello all! It was great to meet at PyCon

Wow! conda-pypi even supportd mapping the just-introduced extras from CEP 44! https://conda.org/learn/ceps/cep-0044 https://conda.github.io/conda-pypi/developer/marker-conversion/#optional-dependency-extras

CEP 44 - Optional dependency groups | conda.org

Title Optional dependency groups

Hey @vernal kettle, yup we were very involved with that standard and the conditionals one for this use case

Question about the CEP 44 match spec for extras: how do users specify multiple extras? I was reading it yesterday and it wasn't clear to me if you can write them comma-delimited, like in python-packaging-land.
