Error loading Jupyter Notebook Extensions

Question

I am using a Macbook with OS Sierra, and running Python 3.6.1 and Jupyter Notebook Server 5.0.0 I installed Jupyter Notebook extensions, following the instructions as mentioned

Answer 1

I had the same error for a long time. Reinstalling nbconfig, changing settings, giving it extra time to load, validating installation before opening the notebook, etc. did not help.

What worked for me in the end was switching browsers! I switched from Safari on my Mac to Chrome and things are working perfectly! (Safari Version 13.0.2, mac OS High Sierra 10.13.6, Chrome Version 83.0.4103.61)
