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 solved my problem by switching to the base environment in Anaconda and installing those packages. At the very beginning, I created a new environment in Anaconda because some conda-forge packages could not be installed. I used 'pip install' in my new environment. I installed those packages and the tab was not showing. The reason is even if I activated the new environment, the jupyter notebook is still initialed in the base environment. That is why the jupyter nootbook said 'no module found' in the beginning.
