Load a sample picture and learn how to recognize it.

Load a second sample picture and learn how to recognize it.

is there a solution to this error message that appears

[olimattison]

I think downgrading numpy is what got rid of that for me.

[flerken42]

Downgrading Numpy version did the trick for me. I used:

pip install numpy==1.26.4
