Dying Kernel on Apple M1

[CaptainMalick]

I was previously using Julia 1.6.3 on Rosetta and Python 3.9 installed for intel, with no issues. I've now moved to Julia 1.7.1 running natively on ARM, with Python 3.9 to match. I've installed PyCall using Pkg.add and Pkg.build, but the Julia kernel dies every time I attempt "using PyCall".

EDIT: Seeing the comment below, I tried it directly CLI Julia rather than in a Jupyter notebook, and I am indeed getting "No module named site"

I am getting an error that is probably the same. I am running Julia natively on an M1 Pro and am getting an ImportError: No module named site.

Works for me on M1 (with Conda python). What python are you trying to link with?

[SebastianAment]

I first tried it without changing the ENV["PYTHON"] entry. I believe this should've defaulted to usr/bin/python3, which is currently

Python 3.8.9 (default, Oct 26 2021, 07:25:53) 
[Clang 13.0.0 (clang-1300.0.29.30)] on darwin

After that failed with the above error, I first checked my Conda python

(base) MacBook-Pro:SEA python3
Python 3.8.8 (default, Apr 13 2021, 12:59:45) 
[Clang 10.0.0 ] :: Anaconda, Inc. on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> exit()
(base) MacBook-Pro:SEA sebastianament$ which python
/Users/sebastianament/miniconda3/bin/python

And then tried

ENV["PYTHON"] = "/Users/sebastianament/miniconda3/bin/python"
"/Users/sebastianament/miniconda3/bin/python"

Any ideas what else I could try?

I had the same error, I worked around it by adding the Conda package and then manually re-building the PyCall package with ENV["Python"] unset (which will use conda if the Conda julia package is installed). I'm not familiar enough with PyCall to know for sure if it's expected to work without the Conda julia package.
