Juoyterlab & Anaconda error when trying to import matplotlib

JupyterLab
1

Hello,

I am a new learner. I am getting familiarized with python, Anacoda (env) and coding in general. I am taking a python online course, and we have a simple test of trying Jupyterlab, but when I tried to run the code I get an error.

The code I am trying to run is:

a={1,2,3,4}
b={-1,-2,-3,-4}
import matplotlib.pyplot as plt

but I get a very long error. I tried:

  1. uninstall and install anaconda
  2. use jupyterlab online
  3. install jupyterlab desktop

Until now nothing works. The error I get is:

ModuleNotFoundError Traceback (most recent call last)

23 try:

25 except ImportError as exc:

12 ARRAY_FUNCTIONS = set()

ModuleNotFoundError: No module named ‘numpy.core._multiarray_umath’

During handling of the above exception, another exception occurred:

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!

Importing the numpy C-extensions failed. This error can happen for
many reasons, often due to issues with your setup or how NumPy was
installed.

We have compiled some common reasons and troubleshooting tips at:

https://numpy.org/devdocs/user/troubleshooting-importerror.html

Please note and check the following:

  • The Python version is: Python3.9 from “C:\Users\moniq\anaconda3\envs\env1\python.exe”
  • The NumPy version is: “1.26.1”

and make sure that they are the versions you expect.
Please carefully study the documentation linked above for further help.

Original error was: No module named ‘numpy.core._multiarray_umath’

The above exception was the direct cause of the following exception:

ImportError Traceback (most recent call last)

ImportError: Error importing numpy: you should not try to import numpy from

I tied many things more but I think I ended up making everything worst.
Please let me know if you have an idea of how I can fix this problem.

Thank you in advance
