Import error while trying to run jupyter notebook

Question

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):

    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

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? – Inshrine

Answer 1

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

Thanks, it partially solved my problem, I've edited my question with the now error... – Chenay

@BenedekDér Try running pip install pysqlite2 to see if it resolves that error – Creaky

This resolves an issue which appears in various different forms, related to zmq, pywin32, Pycharm and Anaconda (64-bit). In my case, when I was starting Jupyter from the Anaconda base environment everything worked normally. With other environments I would get an error, even if jupyter notebook was invoked from Anaconda Prompt, independent of Pycharm. Setting up a clean environment only, didn't help. What did help was setting up a clean environment and then running the uninstall/install of pyzmq with pip, from the terminal, within the activated environment. – Screening

Answer 2

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)

Answer 3

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

conda install pyzmq=22

Answer 4

• Open Anaconda Navigator

• Go to Jupyter Notebook Setting (icon on the right hand side corner)

• And select install specific version After installation select new installation and open it. It will work !!

Answer 5

This is due to a change in module structure with jupyter notebook version 7. Downgrading the notebook version to 6.5 worked for me. Maybe this can work pip3 install notebook==6.5.5

At the time the OP was posted, this didn't involve Jupyter Notebook 7+ as it didn't exist. Additionally, the original post was directed at using the Aanconda distribution and you should hesitate to ever advise using pip to install anything where there is Anaconda/conda recipe. The choice was made to use Anaconda/conda as the primary package manager and that should always be the primary way to adjust the environment(s). – Pyrophyllite
