Fixed by @abc.
Here are a few hints to solve this problem.
Good luck with the rest of the specialization 
As the topic states all tests are passing so how is redirection to irrelevant topic supposed to help in resolving the issue? I wasted an hour trying to find the correct input for the required parameter, the tests are passing correctly, the log output indicates there’s an issue with libraries not loading. What’s the fix for that? Thank you

Even though the warning messages seem to indicate otherwise, the libraries work fine. If you come across this error, double check your implementation and pay attention to the hints.

That’s why I detest Python with a passion… The amount of time wasted on waddling through error messages that have nothing to do with the actual problem… Fixed now and onto the next one
