Can't launch Jupyter Notebook ModuleNotFoundError: No module named 'resource'

Question

I've been using Jupyter Notebook from the command line for a month now, today I didn't shut the running notebook and put my laptop to sleep for 4 hours. After turning my laptop back on I tried to run the notebook again and I'm getting the same error ever since. Please help me out.

Traceback (most recent call last):
  File "c:\users\chinmay\appdata\local\programs\python\python38-32\lib\site-packages\IPython\utils\timing.py", line 27, in <module>
    import resource
ModuleNotFoundError: No module named 'resource'

During handling of the above exception, another exception occurred:

Answer 1

Open this file: c:\users\chinmay\appdata\local\programs\python\python38-32\lib\site-packages\IPython\utils\timing.py

1. change import time to import timeit
2. change time.clock to timeit.default_timer

This worked for me, should work for you.

Answer 2

conda update --all

this working

Answer 3

For me this happened while trying to install some other pip libraries. Looks like one of my pip libraries got downgraded and that caused this error. So upgrading it back resolved the issue.

pip3 install --upgrade jupyter-console
pip3 install --upgrade jupyter
