Hi,
I tried to execute the 'simulation' example but got an error message for the cell:
# Take a sample picture
img = cam.get_image(plot=False)
plt.imshow(img)
The error message is the following one:
RuntimeError Traceback (most recent call last)

598 if offset.ndim != 1 or offset.shape[0] < 1:
--> 599 raise RuntimeError('no proper offset provided')
600 if not offset.flags.contiguous:
601 offset = offset.copy()
RuntimeError: no proper offset provided
I am running python 3.8 on a Mac with Intel. Other examples which did not include hardware .dlls worked in the past. I also checked that I was running the correct branch.
What could the issue be?
Best,
L.
