Based on this Answer from Matlab staff :

Anaconda python is not supported. You have to use the supported python implementation and ensure any necessary packages.

The python version supported also differs based on the Matlab release you are using. Check your release documentation for the version number supported.

Can you try loading python as out of process and see if you get the same error ? https://www.mathworks.com/help/matlab/matlab_external/out-of-process-execution-of-python-functionality.html#:~:text=To%20run%20out-of-process,variable%20in%20the%20Python%20environment.&text=To%20create%20this%20list%20out,execution%20mode%20to%20"OutOfProcess"%20.

The following post is also about TCL error. The cause was wrong version of TCL library. I am not sure what is the correct version for you. https://www.mathworks.com/matlabcentral/answers/525545-calling-python-function-from-matlab-when-using-python-tkinter-results-in-tclerror-can-t-find-a-usa

Yes when I load python as out of process ,I get the same error.Thank you very much for your answer. In fact, I also saw this message about TCL error, but I didn't quite understand what he meant at the time. After your confirmation, I can check this question again
