[Solved] Import OpenCV on jupyter notebook

I tried installing OpenCV on Windows 10 using pip.
I used this command-
pip install opencv-contrib-python

After that when I tried importing cv2 on command prompt, it was successfully imported-
Importing cv2 successfully through command prompt

When I tried importing it on jupyter notebook, this error popped up-
Error when importing cv2 on jupyter notebook

This is the python version I’m using-
Python version that I am using

This is pip list and as I’ve highlighted, opencv-contrib-python version 3.4.3.18 is installed-
pip list

Then why can’t I import OpenCV on jupyter notebook, like tensorflow or numpy are also in pip list and I’m able to import them both through command prompt and also on jupyter notebook.

Please help. Thanks a lot.

Solution #1:

You have installed openCV in Python running on your Terminal, not into the working environment which Jupyter Notebooks is running from.

Whilst in Terminal write:

py -m pip install opencv-python

When you use pip list

You should see opencv-python 3.4.3.18

You should open the anaconda prompt and then type:

conda install opencv 

It should work.

Solution #3:

It seems like you run jupyter not from conda environment, that has opencv module installed.
try to do this:
conda activate <your environment>

conda install jupyter
jupyter notebook

after that try to “import cv2”
