Install OpenCV for Python on macOS Catalina

Perfect! Thank you!

Thanks for the video it was really informative, I got the following error. Any suggestion please?
ERROR: Could not build wheels for numpy, which is required to install pyproject.toml-based projects

[notice] A new release of pip available: 22.3.1 -> 23.1.2
[notice] To update, run: pip install --upgrade pip
[end of output]

note: This error originates from a subprocess, and is likely not a problem with pip.
error: subprocess-exited-with-error

× pip subprocess to install build dependencies did not run successfully.

I can not save the code in the python virtual environment. I dont know why

thanks

it really helped me 🥰❤️

Works!!! Macbook 2020 catalina

when image window is getting open i am not able to close and jupyter kernel is crashing as well.

Very helpful in both vim editor and opencv. I really appreciate it.

really very helpful video :) . seriously I'm stuck on apple silicon but this method work in apple silicon :). I'm very happy

Thank you for a very good guide :)

thank you you're the best! simple and to the point

you are the best.

I'm getting like : no such as job

Thank you! I am very stupid in programming, so it took me a few days to install opencv. Thanks for the working version of the installation. Hope I can create a program.

Thank you. It really helped out.

UnsatisfiableError: The following specifications were found
to be incompatible with the existing python installation in your environment:

Specifications:

- opencv -> python[version='>=2.7,<2.8.0a0|>=3.5,<3.6.0a0|>=3.6,<3.7.0a0|>=3.7,<3.8.0a0']

Your python: python=3.8

If python is on the left-most side of the chain, that's the version you've asked for.
When python appears to the right, that indicates that the thing on the left is somehow
not available for the python version you are constrained to. Note that conda will not
change your python version to a different minor version unless you explicitly specify
that.

What about this👆 problem?

this is the best and clearest video i've watched on this

let's say i have installed like you did. can i use openCV now from PyCharm ?
Thanks for this mate!!!

thank you. This tutorial is really helpful.

Thanks a ton! This is the simplest way I have found online to get my OpenCV working. Regarding to the last part, press any key to exit, you'd have to keep image widow on focus to terminate the program.

Amazing video
But i have a little problem and would be very thankful for the help,
I followed the setup steps and was able to display images successfully
Now i want to use jupyter lab in the virtual environment
So i used the command jupyter-lab in the environment to open jupyter notebook
After that i ran a simple program but it is showing that "No module named OpenCV"
How can i rectify this problem?
I am running it in the jupyter lab terminal by going to the position of the notebook through cd

Thank you for the video, I followed the steps but got the following error "This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem." any help is appreciated. I am running python 3.7 on macOS Catalina, I have installed Qt5 but did not help. thanks

thank you ıt's perfectly run

why cant i use opencv in pycharm built in ide

what terminal are you using? I try with the default mac terminal (the black one) and it doesn't work

...any idea how to configure eclipse (macOS) to use openCV... my python OpenCV program runs (using the virtual env as per the video) but not via Eclipse... any help appreciated

Thanks for your video!! It's help me install Opencv3 & Python3.7 successfully.

pip install pencv-phython doesn't work for me=, I get "ERROR: Could not find a version that satisfies the requirement opencv-python (from versions: none) ERROR: No matching distribution found for opencv-python" -0 any ideas?
