Troubleshooting installation issues with M1P MBP, conda environment, and arviz

[HaXAlvin]

Hi, just want to let you know, and hope can help somebody who also has the same problem.

I am using M1P MBP (Ventura 13.2.1).
I faced some issues when running conda env create -f bap.yml.
Sorry that I can't reproduce the error, but the error is about installing hdf5 and netcdf
I ran brew install hdf5 netcdf first to stove the problem.

The env installed successfully, but I still have an error trying to import arviz
The error shows:
ImportError: dlopen(/Users/alvin/opt/anaconda3/envs/bap/lib/python3.6/site-packages/netCDF4/_netCDF4.cpython-36m-darwin.so, 0x0002): symbol not found in flat namespace '_nc_close'
There's also a warning:
WARNING (theano.configdefaults): install mkl with ``conda install mkl-service``: No module named 'mkl'

I ran conda install -c conda-forge netCDF4 to fix them.

Great! I had this problem when I created my env with conda env create -f bap.yml !
Thanks for sharing, I always encounter various version incompatibilities when running code in my own created environment, it's more friendly to use the book's environment!
