Expected behavior

This warning seems to be expected with Python 3.11: https://discourse.jupyter.org/t/debugger-warning-it-seems-that-frozen-modules-are-being-used-python-3-11-0/16544

Actual behavior

This is not a bug.

The question is: What should be done here?

1. Nothing (it's just a warning).
2. Pass -Xfrozen_modules=off to python.
   • = disable frozen modules.
3. Set PYDEVD_DISABLE_FILE_VALIDATION=1.
   • = disable this validation.

Anything else?

No response

Latest Docker version

2. Pass -Xfrozen_modules=off to python.

Unfortunately, I'm not yet familiar with frozen modules, so I can't answer this question, sorry :(

My recommendation is to leave as is at system level. it's just a warning.

If it bothers anyone,PYDEVD_DISABLE_FILE_VALIDATION=1 can be set at user level.

Just ignore this warning. It's a warning so you shouldn't have any problems running your scripts because of it.

@JustaGreenhand you mentioned not a problem, but 3 possible solutions.
And my current advice is to use the first solution.
