pip3 install opencv-python
to get the cv2. I'm not sure when opencv-python became available. I'd been building opencv by hand, but when I looked a few weeks ago, there it was. I'm using cv2 with Python3 in a VM that's running ubuntu/trusty64.

First do run these commands inside Terminal/CMD:
Copyconda update anaconda-navigator
conda update navigator-updater
Then the issue for the instruction below will be resolved
For windows if you have anaconda installed, you can simply do
Copypip install opencv-python
or
Copyconda install -c https://conda.binstar.org/menpo opencv
if you are on linux you can do :
Copypip install opencv-python
or
Copyconda install opencv
Link1 Link2
For python3.5+ check these links : Link3 , Link4
Update:
if you use anaconda, you may simply use this as well (and hence don't need to add menpo channel):
Copyconda install -c conda-forge opencv

This happens when python cannot refer to your default site-packages folder where you have kept the required python files or libraries
Add these lines in the code:
Copyimport sys
sys.path.append('/usr/local/lib/python2.7/site-packages')
or before running the python command in bash move to /usr/local/lib/python2.7/site-packages directory. This is a work around if you don't want to add any thing to the code.

May 25, 2022 -
Hi, I really need help. I've been crying about why it's not working for 2 hours. I know this error is very famous and common for python, but I can't fix this at all.
So, I was trying a few hand-tracking codes, with the code "import cv2" but all of the codes ended up saying ModuleNotFoundError: No module named 'cv2'.
I have done installing these codes already,
- pip3 install OpenCV-python
- pip3 install OpenCV-contrib-python
I'm using Python(Python3) 3.10(64bit), Spyder as software, Conda 4.12.0
I am quite new to python, so I may ask lots of basic questions. please help me.

If there were no issues/errors when you installed OpenCV, but it’s not being found when you try to import it then it’s not installed for the version of Python (or more likely the virtual environment) you’re trying to use it in.
