First do run these commands inside Terminal/CMD:
conda 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
pip install opencv-python
or
conda install -c https://conda.binstar.org/menpo opencv
if you are on linux you can do :
pip install opencv-python
or
conda 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):
conda 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:
import 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.

April 7, 2024How do I fix the issue moduleNotFoundError: No module named 'cv2' ?
it just seems that u are missing open cv all u need to do is install that it may be different depending on what u are using if u are using automatics repo, then it will probably be done from within the venv u can manually activate it from in cmd (cmd does not open in the folder by default so cd Your/StableDiffusion/path/here) by opening the activate.bat file found in stable-diffusion-webui (root) root\venv\Scripts\activate.batthen u will need to run pip install opencv-python else just install it from cmd with the same command pip install opencv-python More on reddit.com

r/StableDiffusion on Reddit: How do I fix the issue moduleNotFoundError: No module named 'cv2' ?
October 16, 2022 -
Normally I would just look up the solution rather than ask but from what I've seen, most people tend to have this issue differently, hence why I needed to ask, but also because I'm completely ignorant on this matter. I don't think I could fix this on my own unless I found an answer that told me how step by step.
Anyway, as I was installing diffusions for the very first time, the cmd kept giving me this issue repeatedly.
Relauncher: Launching...
Traceback (most recent call last):

As I've said above, since I'm ignorant on this topic, I have no idea what that really means or how to fix it so any help would really be great. I really don't want several hours to be wasted on this lol

1)Delete all your existing opencv installation
2) Reinstall it again in that way (python 3)
python -m pip install opencv-python
3) And Voila!
