Logic error when trying to open image with pyscleranto_prototype

Getting the following error when trying to open a single channel tiff image with cle.imshow():

Command:

cle.imshow(single_channel_image, color_map='Greys_r')`

Output:

Hi @sebgoti ,

can you check if the graphics card is properly installed? You find some hints here: https://github.com/clEsperanto/pyclesperanto_prototype#troubleshooting-graphics-cards-drivers

Let me know if this helps! If not, it would be good to learn some details about the computer you are running the notebook on.

Thanks!

Best, Robert
