python and openCV installation

[dejhost]

All went wrong... so I deinstalled all python versions, deleted all folders and installed once more, this time using the "python-3.7.8-amd64.exe". And Yes, I checked the "add to path" option.

And voila: at last one big step towards a working environment:

C:\>pip -V
pip 20.1.1 from c:\users\jost\appdata\local\programs\python\python37\lib\site-packages\pip (python 3.7)

C:\>pip install opencv-python

>>> import cv2
>>> cv2.bilateralFilter
<built-in function bilateralFilter>

Wow. Almost there!!!

Almost, because:

>>> cv2.adaptiveBilateralFilter
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: module 'cv2.cv2' has no attribute 'adaptiveBilateralFilter'
>>>

According to my thread here, , the adaptiveBilateralFilter should be in the opencv Version 4.2.
