title: Import OpenCV on jupyter notebook
body: <p>I tried installing OpenCV on Windows 10 using pip.
  I used this command-
  pip install opencv-contrib-python</p>
  
  <p>After that when I tried importing cv2 on command prompt, it was successfully imported-

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

  <p>This is the python version I'm using-

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

  <p>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.</p>
  
  <p>Please help. Thanks a lot.</p>
