Where can I find the ledpixels module?

[epl]

Hello

In an online course from school my Python programms start with:

from ledpixels import *
from time import sleep

When I try to run this code in PyCharm, it can't find the ledpixels module. I already asked google, but could not find it.

Any ideas how to get the school examples running in PyCharm?

Regards
