@sree_datta
First of all, thanks a TON for these detailed step-by-step instructions to install arguably one of the most difficult packages to install on Windows.
It seems these steps worked for you and several others at the time (~ 3months ago).
Just today, i replicated the steps exactly, but got stuck at installing pymc3 using pip inside the conda environment.
when i run pip install pymc3 i get:
ERROR: Could not find a version that satisfies the requirement pymc3 (from versions: none)
ERROR: No matching distribution found for pymc3
I have Windows 10 X64
MSYS2 installed with g++ version 11.3.0 (paths added to top of user environment variables as indicated in instructions)
Anaconda3 2021.11 with python 3.9.7 bundled within
pymc_env environment created with python version 3.10.4 (that is what is picked up by conda-forge channel when environment was created).
Would you know if there is anything i might be missing here ? Could it be related to your 3rd question above in Q&A on version conflicts during upgrades by Anaconda, python , g++ etc. ?
Thank you ,
