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 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.

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

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"

  • Please show the output of import sys; print(sys.prefix) for both the cmdline python and your notebook python.
  • Are you sure you installed opencv in the same virtual environment you are using with Jupyer?
  • Hello Deets, thanks for replying. On cmdline, output is- C:\ProgramData\Anaconda3 On jupyter notebook, output is- C:\Users\HP\Anaconda3
  • Hello Ed. Thanks for replying. Earlier when I installed tensorflow, I used- pip install tensorflow and after that I could import tensorflow both on command prompt and on Jupyter notebook. Then why for OpenCV, I'm facing this problem?
  • Hello Michael. Thank for replying. I was wondering that where exactly did I install OpenCV then. What does pip list show? I mean, I am able to import cv2 on command prompt, but not on python shell and neither on jupyter notebook. So is it like command prompt, anaconda jupyter notebook and python shell independent of each other?
  • It would have been installed into your Python Shell. So you could work with opencv2 within the Python PATH. Jupyter needs you to install it into your Windows CMD, to access that module. Though I must confess I am sure someone else more technically minded is better able to answer that question. Also I'm fairly sure the library you installed is not OpenCV but a module for contributing to open CV. See here:
