Problem with the demo file

[LouLaurent]

I encounter 2 problems when i test the demo file.
First, the version of openCV in the requirements text file doesn't exist, so i change the version :
opencv_python==4.2.0.32

Then, when i try to launch the demo, i have this error :
Using TensorFlow backend.
Traceback (most recent call last):
File "real_time_video.py", line 1, in

Can you help me with this ?
Thanks,
Lou

In terms of opencv, I have not had any problem with python 3.6.8.
The other problem I have not solved, so I am still waiting for help. I don't know if it is needed to install tensorflow(in that case, which version), because it does not appear on the requirements.txt

I solve the problem, Tensorflow is not compatible with Python 32 bits, so you need to download Python 64 bits !
