I am trying to start jupyter notebook from my terminal, like i've done million of times before. Out of the sudden, a following Module Error is appearing and I can not find a solution anywhere.

`

(base) me518@PHS024636 ~ % conda activate mageckenv
(mageckenv) me518@PHS024636 ~ % jupyter notebook
Traceback (most recent call last):
  File "/Users/me518/miniconda3/envs/mageckenv/bin/jupyter-notebook", line 5, in <module>
    from notebook.notebookapp import main
  File "/Users/me518/miniconda3/envs/mageckenv/lib/python3.7/site-packages/notebook/notebookapp.py", line 59, in <module>
    from tornado import httpserver

    from tornado.netutil import ssl_wrap_socket, _client_ssl_defaults, _server_ssl_defaults
ModuleNotFoundError: No module named 'tornado.netutil'

`

Any ideas with what's going on?

I tried activating all of my environments, nothing works.

  • Looks like module tornado.netutil is not available, even though you believe it is. Check your assumptions. https://duckduckgo.com/?q=miniconda3+tornado.netutil+module&t=osx – duffymo Dec 07 '22 at 16:19

It looks like you already tried to pip install tornado (since you also posted this). Maybe do the following after conda activate mageckenv:

python -m pip install tornado

and see if this fix your problem.

Sometimes pip may use different environments and python -m pip makes sure it's using the specific pip you want.
