python - 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):

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:UsersUserAnaconda3libsite-packages otebookservicessessionssessionmanager.py", line 10, in import sqlite3

File "C:UsersUserAnaconda3libsqlite3dbapi2.py", line 27, in

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

During handling of the above exception, another exception occurred:

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
