python - Import OpenCV on jupyter notebook

Question

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-

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

This is the python version I'm using-

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

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.

Answer 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
