Issue with PollingObserver

[BornKrefeld]

I got following message:
Traceback (most recent call last):
File "D:\04_Pycharm Projekte\General_Projects\Py_Security\XS1 PY Watchdog_template1.py", line 2, in
from watchdog.observers import PollingObserver
ImportError: cannot import name 'PollingObserver' from 'watchdog.observers' (D:\04_Pycharm Projekte\General_Projects\Std_pgm.venv\Lib\site-packages\watchdog\observers_init_.py)

I took a look at the site package watchdog\observers. This site package contains a class PollingObserver. Neverthless this class was not considered.
I work under pycharm and used a watchdog version 6.0
