Compability with joblib

[Tijmen W]

Hi all,

 I have been using pyinstaller recently to transform a package of .py files t an executable with a gui, created via PySimpleGui.

The problem lies with some functions that I am using, which are based on joblib.When the .exe runss into the parallel processing command, mutiple windows pop (#cores) up and the .exe stops responding. 

I don't run into this problem when executing the files from Spyder.

Any help here would be appreciated.

Kind regards,

Tijmen Wartenberg

There’s a multiprocessing.freeze_support() which has to be called in your if __name__ == "__main__:" block. I’ve never used joblib so I don’t know if they’ve wrapped it up in their own API but it should be enough just to use the original from multiprocessing directly.
