Installation problem-cannot import pymc

1

Hi all, i installed pymc with conda create -c conda-forge -n pymc_env “pymc>=5” （window11）， while i got the following error “UnicodeDecodeError: ‘gbk’ codec can’t decode byte 0xba in position 2367: illegal multibyte sequence” when i import pymc.
Anyone knows how to fix this? Thanks a lot.

Seems like an arviz error. Perhaps best to open an issue on their GitHub repo

thanks

Sounds like this issue: UnicodeDecodeError when i import arivz · Issue #2274 · arviz-devs/arviz · GitHub

As suggested, reinstalled the pymc with the arviz 0.15.1, i got another error “ImportError: DLL load failed while importing _imaging:”
