No modue named _ctypes

[Alberto Fornés 22]

Hello, I have started working with Python4Delphi. I have installed Python 11, and in environment variables is set the path to the python exe folder and the scripts folder. I have installed with pip the modules of the examples of the webminar II of the tutorials (python4delphi/Tutorials/Webinar II at master · pyscripter/python4delphi · GitHub). I can't get to run the scripts without getting errors like: "no module named _ctypes", it's a required module for Pandas. I have also got this error with the unicodedata module, I installed with pip unicodedata2, but it doesn't work either. Any suggestions for things to check?

Is this a failure to load the python DLL or an error when executing python scripts?

Are you using the latest sources from the Github repo?

If you are using python version 3.11.1 then please try with  version 3.11.0 or earlier.   There is a change related to the loading of dynamic libraries (dll) in 3.11.1, that I am looking into.  See regression with latest Python 3.11.1 and _socket not found · Issue #100171 · python/cpython (github.com)

Hello, and thanks for your reply. The python  DLL 3.11 can be loaded because I can run basic scripts, but when try to execute scripts that imports modules like matplotlib, numpy, pandas, etc raises that errors.  I confirm that 3.10.9 runs ok without that errors.

A workaround for this python regression has been committed to the repo.
