Support

did proper install for your github site, tried to run smooth.py --code could not find pantilthat
File “smooth.py”, line 6, in
import pantilthat
ImportError: No module named pantilthat

any help appreicated.
regards, Tom

That likely means the install actually targeted a different Python version than what you’re using. What’s the output of:

python --version
pip list | grep pantilthat
pip3 list | grep pantilthat

?

pi@raspberrypi:~ $ python --version

OK, so it looks like:

  • you’re running smooth.py under Python 2, but
  • the pantilthat Python library isn’t installed at all

Try doing the manual install documented at GitHub - pimoroni/pantilt-hat: Python library for the Pimoroni PanTilt servo and lighting HAT, then run pip list | grep pantilthalt again. Assuming you see it listed now, then try smooth.py again.

here’s another output using an openCV shell that i hope to use with pantilt
