ultralytics libGL error

[sliu736]

Hi I am trying to load cv2 package in fabrics notebook and the error is: 

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

I've tried to install both opencv-python and opencv-python-headless, but neither of them works.

Hi, @sliu736 

Thanks for FabianSchut's positive reply. When I install only the opencv-python package I get the same error as you, but after installing the opencv-python-headless package, the import command executes fine. You can try installing both packages

If I look at the documentation of the cv2, you should only have one package installed at a time: https://pypi.org/project/opencv-python/. Can you try to uninstall all four potential packages: 
opencv-python
opencv-contrib-python
opencv-python-headless
opencv-contrib-python-headless

and reinstall only one? 

[FabianSchut]

And probably you want to reinstall the opencv-python-headless, since that one is less depend on other packages: https://stackoverflow.com/questions/55313610/importerror-libgl-so-1-cannot-open-shared-object-file-n...

Hi here is the list of packages I have.

And now cv2 cant be found. So confusing

[FabianSchut]

Can you create a new environment in Fabric and install the headless version once there?

[sliu736]

Hi, that is already my current solution. And more confusing is that even if the only package installed was opencv-python-headless, opencv-python still exists in the pip list.
