Throwing an error while executing the tqdm module

[Debabrata Sarkar]

The --onedir package (macOS/Catalina) throwing an error while using 'tqdm' module for an iterable, but no errors while bundling it. Any help, please.

Having seen a similar error before, my hunch is that this is related to tqdm's use of multiprocessing – and not *first* calling multiprocessing.freeze_support() in your application. I have not tested this in tqdm's case however.

See e.g. GitHub issue 683

Many a thanks! Resolved.

from multiprocessing import freeze_support

freeze_support()
