Since the upgrade to version 1.4.2, we encounter the following issue on a Thorlabs Zelux Monochrome sCMOS camera:
Things are fine in 1.4.1.
Minimal code to reproduce bug
from pylablib.devices import Thorlabs
serialnumbers = Thorlabs.list_cameras_tlcam()
cam = Thorlabs.ThorlabsTLCamera(serialnumbers[0])

Thank you for the kind words!
You are right, this is a bug intrduced when adding the color mode, which breaks the code on monochrome cameras. I'm not quite sure how it made through the testing...
To fix it for now, you'll need to replace the file pylablib/devices/Thorlabs/TLCamera.py with the fixed version. Otherwise, this will be fixed in the next release.
