ZeroDivisionError: float division by zero

General

• Operating System: windows 11
• Python version: 3.8.3
• Pandas version: 1.4.2
• Pandarallel version: 1.6.1

Acknowledgement

• My issue is NOT present when using pandas without alone (without pandarallel)
• If I am on Windows, I read the Troubleshooting page before writing a new bug report

same problem here, one of the progress bars turns red at some percentage point (different every time) and stops progressing, then after the others complete, I get the division by zero error. It DOESN’T happen with progress_bar=False (im using python 3.9.0, windows10 running it in vscode)

Oops. Yeah, sorry I thought this was on diffxpy. My bad.
