Error loading server extension jupyter_nbextensions_configurator #1513

Hi, I followed the instructions to install jupyter-contrib-nbextensions. However, when I launch jupyter notebook, I got the following ERROR:

Error loading server extension jupyter_nbextensions_configurator
Traceback (most recent call last):

ModuleNotFoundError: No module named 'jupyter_nbextensions_configurator'

I then tried the solution to a previous similar issues: 

jupyter serverextension list
jupyter serverextension disable nbextensions
jupyter serverextension disable nbextensions --user
jupyter serverextension disable nbextensions --sys-prefix

However, it does not work. I also tried to create a new environment without jupyter-contrib-nbextensions, but again, when I launch jupyter notebook, I still got the same error message.

Followup: I manually changed the file .jupyter/jupyter_notebook_config.json and set jupyter_nbextensions_configurator to false. Then I don't see this ERROR when launching notebook.

However, I still cannot import any module. I have the package pomegranate installed, but when I tried to import, it shows:

ModuleNotFoundError                       Traceback (most recent call last)
<ipython-input-3-1cb5711ea5a2> in <module>()
----> 1 from pomegranate import *
         2 import time
         3 import pandas as pd
         4  import numpy as np
         5 import matplotlib.pyplot as plt

ModuleNotFoundError: No module named 'pomegranate'

Before installing jupyter-contrib-nbextensions everything worked fine. All the problems happened after I tried to install it. I don't have a clue on how to solve it. Any advice? Thanks!
