Question:

I thought the problem should be on windows platform. Is there any platform compatability problem?

@zueskalare This might be because you are using embedded in Linux without using mechanical-env before running you script

for example after you activate your venv
instead of python ./test.py you should use mechanical-env python ./test.py to run your script if you are using pymechanical embedding.
