I have an issue with OpenCV in windows 10. Whenever I try to import OpenCV I get following error.

import cv2
 ** On entry to DGEBAL parameter number  3 had an illegal value
 ** On entry to DGEHRD  parameter number  2 had an illegal value
 ** On entry to DORGHR DORGQR parameter number  2 had an illegal value
 ** On entry to DHSEQR parameter number  4 had an illegal value
Traceback (most recent call last):

Any help will be appreciated. Thanks.

Python 3.9 is very new you should go back to 3.86 and write this in cmd

pip install opencv

First, you can find help here: How do I install opencv using pip?

Then, try the following steps:

  1. Downgrade your current python version to python 3.8. Go there for more informations: how can I downgrade from python 3.7 to 3.6 in windows. You can also create a virtual environment with python 3.8: https://uoa-eresearch.github.io/eresearch-cookbook/recipe/2014/11/26/python-virtual-env/
  2. Type this command line in cmd: pip install opencv-python
  3. Check if opencv package is installed: python -c "import cv2"

For step 2, be sure your pip version is updated.

I hope it'll help you =)
