See also #11181, which solves this problem and, I believe, introduces a much easier way to handle this in general.

#12295 is the better solution, since all the dependencies are now in a later version of nixpkgs, no need to pull them from pypi anymore.

I vote against merging this in favor of #12295.

[purcell]

#12295 is better than this, but I suggest from painful experience on python+nix projects that #11181 is the better choice for the long term, because it's unhelpful to be tied to the python library versions in nixpkgs: you will eventually end up adding overrides again, or being blocked on upstreaming and testing version changes in nixpkgs. The poetry/poetry2nix route does full dependency resolution, and can use newer pypi packages when desired or necessary, all without needing to update nixpkgs, and while retaining all the nix benefits.

[con-f-use]

Yes, I'm in favor of the poetry to nix route, I was just saying, if we wanted a working nix-shell right NOW, this PR should be merged and #11181 when everyone is happy.

This has some merge conflicts that need to be resolved, now

I think that in any case, this one can be closed, since #12295 superseded it and has since been merged.

[EdenEast]

Since #12295 has been merged I will close this pr as she'll.nix has all it's dependencies.
