PyMC3 Window10 Installation Issue

Hi,

I ran into an “environment” issue when I tried to install PyMC3 in my new HP Z-book computer running windows 10. Have anyone ran into the same issue and help? Thank you very much in advance.

Here is the output:

(mypm3env) PS C:> conda install -c conda-forge pymc3
Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.
Solving environment: failed with repodata from current_repodata.json, will retry with next repodata source.

UnsatisfiableError: The following specifications were found to be incompatible with each other:

I followed the instruction and ran the following command in sequence:

conda create -c msys2 -c conda-forge -n mypm3env python=3.8 mkl-service libpython m2w64-toolchain scipy matplotlib pandas

conda activate mypm3env

conda install -c conda-forge pymc3

I ran into a similar issue in MacOS. I think this problem is not about the OS but about Conda itself. I have been having issues installing many packages with Conda lately.

I ended up solving the problem by installing PyMC3 with Pip, so I would try that if I were you.
