What happened?

I was trying to install scanpy=1.9.6 using conda in a python=3.9 environment that had 1.9.5 working with seaborn=0.13. Conda raised a solving issue due to package scanpy-1.9.6-pyhd8ed1ab_0 requires seaborn !=0.13.0, but none of the providers can be installed I tried the second build (1ab_1) and the error stayed: package scanpy-1.9.6-pyhd8ed1ab_1 requires seaborn !=0.13.0, but none of the providers can be installed

I checked github and saw that the dependency in pyproject.toml is "seaborn>=0.13.0" but when i checked the conda package's index.json i saw "seaborn !=0.13.0".

The discrepancy between the dependencies is unclear.

Indeed scanpy 1.9.6 required seaborn!=0.13.0, while newer releases have been update to require seaborn>=0.13.0 (when you look here on GitHub, you will find this updated requirement as you mentioned)

If you want to use scanpy 1.9.6 for a specific reason, your environment should use a seaborn version that is not 0.13.x, e.g. the latest 0.12 version.

Does upgrading to the latest scanpy version resolve this issue for you?
