Debugging Jupyter cells fails with "Pip module Unable to parse debugpy output"

Question

I am trying to debug Jupyter notebooks (and also cells in .py files demarked with #%%) but it does not work. After a while the IDE pop up a note Pip module Unable to parse debugpy output,..

Debugging "regular" python files, i.e. no jupyter cells, works fine.

The jupyter log shows:

warn 09:42:53.944: StdErr from Kernel Process     
warn 09:42:53.945: StdErr from Kernel Process self._abc_registry = extra._abc_registry
                         ^^^^^^^^^^^^^^^^^^^
AttributeError: type object 'Callable' has no attribute '_abc_registry'

error 09:43:04.220: Execute_request failure enabling debugging for IW import debugpy;debugpy.listen(('localhost', 0)) RuntimeError: timed out waiting for adapter to connect 

[...]

error 09:43:04.221: Error in execution (get message for cell) o [Error]: Pip module Unable to parse debugpy output, please log an issue with https://github.com/microsoft/vscode-jupyter is required for debugging cells. You will need to install it to debug cells.

}

My environment: Ubuntu 22.04, VSCode, Python 3.11.

I tried different python versions (3.7, 3.10) but the problem persists.

Answer 1

I could solve this issue by making sure that typing is not installed (typing 3.7.4 was added by a 3rd party library)

pip uninstall typing

This post pointed me in the right direction: AttributeError: type object 'Callable' has no attribute '_abc_registry'
