I have the same problem, and I have tried to only import os in user_examples init.py, the same error occurs. Can anyone help?
I have solved this problem, it’s because my server has encrypt software which will convert .py file to binary which will lead to isaac sim recompile failed, without encrypt it can work well with .py encoded as ascii.
