Python script runtime error when published

[hushijin059]

Hello, 

I need help with Python visuals in PowerBI. The python visual displays fine in the desktop file, but when published, it returns a runtime error as below. There is no indication of any packages or code errors in the error message. Can you help? My report was running fine a few weeks ago and started to show this runtime error recently.

Just wanted to add that I am experiencing the exact same issue- report that worked fine last week is now broken with no obvious error message.
