An import error occurs when trying to run jupyter notebook

I'm trying to run jupyter notebook using anaconda (git bash platform), and as I type in jupyter notebook, an import error occurs every time. I tried to lauch it inside an environment, but the same error occured.

$ jupyter notebook

Traceback (most recent call last):

File "C:\Users\User\Anaconda3\Scripts\jupyter-notebook-script.py", line 6, in

from . import (constants, error, message, context,
    ImportError: DLL load failed: The specified module could not be found.

EDITED After reinstalling pyzmq (and I tried reinstalling conda too), the following error occurs:

$ jupyter notebook

Traceback (most recent call last): File "C:\Users\User\Anaconda3\lib\site-packages\notebook\services\sessions\sessionmanager.py", line 10, in import sqlite3

File "C:\Users\User\Anaconda3\lib\sqlite3\dbapi2.py", line 27, in 

from _sqlite3 import *

ImportError: DLL load failed: The specified module could not be found.

During handling of the above exception, another exception occurred:

That's python unable to import sqlite3. Can you do that in an interactive interpreter? – Stop harming Monica

I found a similar issue open on GitHub for zmq. The recommendation by GitHub user harsh23tyagi that seems to work for most is to run the following:

pip uninstall pyzmq
pip install pyzmq

Working with conda env, jupyter notebook worked in (base) env but gave the .libzmq error in (my_env). To be able to run notebooks from my_env, this worked for me :

  • pip uninstall pyzmq
  • pip install pyzmq==20 (no version for pyzmq didn't fix the issue for me)

It seems that updating pyzmq to the latest version fixes this problem for me.

conda install pyzmq=22
