PkgResourcesDeprecationWarning: -PKG-VERSION is an invalid version and will not be supported in a future release

[maungthway]

I tried to import MPRester using this commend and get the following warning. Is there a way to fix this warning?

Code: from mp_api.client import MPRester

Warning: C:\ProgramData\Anaconda3\envs\mp_newapi\lib\site-packages\pkg_resources_init_.py:123: PkgResourcesDeprecationWarning: -PKG-VERSION is an invalid version and will not be supported in a future release warnings.warn(

[pmrv]

This causes a hard crash now for us in pyiron.[1] Please advice on a possible fix, I guess in the short term we can downgrade setuptools.

We are using versions pymatgen==2022.11.7, mp-api==0.30.5 and setuptools==66.0.0.
