Problems import CV2 package

Question

I'm relatively new to image analysis and I want to import the CV2 package. When I run the code import cv2 I receive the following error code:

ImportError: libGL.so.1: cannot open shared object file: No such file or directory

I've looked at answers like this: ImportError: libGL.so.1: cannot open shared object file: No such file or directory

But when I do, the solutions doesn't work For example one solution suggested to run apt-get update && apt-get install -y python3-opencv, but again, when I do, the code does not run. I already tried to uninstall the packages but still the same error.

Someone know a solution?

You may not have it installed via PyPi. I don't know CV2, but should be able to help you. First, go to https://pypi.org and search for the CV2 package because I don't know which one you are trying to use. Then click the copy button next to the console command and go to your command prompt or terminal and paste it there.

I used ```pip install opencv-python``` to instal openCV where cv2 is part of. But still get the same error message... – Paul Engelbert Mar 19 '22 at 12:26
I just checked their PyPI page, they have more advanced install instructions and it says to make sure you did all of these if you get any other import errors. – Hex Mar 20 '22 at 13:16

remove opencv from your environment first. run

apt-get update && apt-get install libgl1

and then "pip install python3-opencv

I receive the error ```invalid syntax``` pointing to the 'u' of 'update'. So jupyter doesn't recognize this as a line of executable code. I work on ipynb file in jupyter lab. – Paul Engelbert Mar 19 '22 at 12:37

@PaulEngelbert are you working on windows or linux? – sharktooth Mar 19 '22 at 12:38
I work on MacOS – Paul Engelbert Mar 19 '22 at 12:41
@PaulEngelbert then no need to use apt-get command, I'd suggest using anaconda environments. – sharktooth Mar 19 '22 at 12:45
It still doesnt work. When I run your code it mentions: 'unknown command ''update''. When I try to leave it out and reinstall python3-opencv, loading the cv2 package still gives the same error – Paul Engelbert Mar 19 '22 at 13:00
