1Hi, please include more photos of the errors, especially near the bottom of the error message, that's ususally where the important ones are. – dsillman2000 Oct 19 '21 at 15:11

Also check that your pip is up to date, too. – Pam Oct 19 '21 at 15:12

1Apparently, your virtual environment is using the recently released version of Python i.e. 3.10 which seems to be incompatible with `numpy 1.19.3`. – sgarizvi Oct 19 '21 at 15:12

Do you have multiple python versions installed? Also make sure you've set your environment variables properly. Also download the version of OpenCV same as that of latest python version in your system. – HIMANSHU PANDEY Oct 19 '21 at 15:12

You seem to be using python 3.10 in your environment. Since it is so new, no pre-built binaries are available for opencv-python and it tries to download source code and compile it on the fly, which fails, because the library is large and has complex dependencies.
What can you do?
You can check the pypi page and see that the latest whl for win64 is for cp39, so python 3.9. So you could do
conda install python=3.9 #install python 3.9 in your current env
pip install opencv-python
this should now pull the opencv_python-4.5.4.58-cp39-cp39-win_amd64.whl and install that.
Even better would be however, to simply have conda handle that for you:
conda install -c conda-forge py-opencv
