[netCDF #EOQ-833825]: Error (mach-o file, but is an incompatible architecture (have 'x86_64', need 'arm64e'))

Hello,

The root of this issue is that the interpreter is trying to invoke libraries 
built for the x86_64 architecture.  There are a couple of potential causes for 
this.  First, homebrew may have installed x86_64-compiled libraries.  I am not 
terribly familiar with homebrew, but it's possible that they may only provide 
binaries for the Intel architecture, or that a command-line argument is 
required when installing packages, in order for M1-compatible binaries to be 
installed.  It's also possible that PyCharm is not properly set to invoke 
libraries using Rosetta2.

Looking at the page you linked, it does not seem to specify using homebrew 
specifically.  You might also have better luck installing using Conda, as 
linked from the page at https://unidata.github.io/netcdf4-python.  Are you able 
to easily install the dependencies from a different source, and see if the 
issue changes or goes away?
