Does W&B use the `multiprocessing` library?

Yes, W&B uses multiprocessing. Add if name == ‘main’ to avoid bootstrapping errors.

Yes, W&B uses the multiprocessing library. An error message like the following indicates a possible issue:

An attempt has been made to start a new process before the current process 
has finished its bootstrapping phase.

To resolve this, add an entry point protection with if __name__ == "__main__":. This protection is necessary when running W&B directly from the script.
