Jetson tx2 can not detect speed and take pics

Hi everyone, I Hope yare fine.

I have jetson tx2 racecar with environment:

NVIDIA Jetson TX2
L4T 32.2.1 [ JetPack 4.2.2 ]
Ubuntu 18.04.2 LTS
Kernel Version: 4.9.140-tegra
CUDA 10.0.326
CUDA Architecture: 6.2
OpenCV version: 3.4.0
OpenCV Cuda: YES
CUDNN: 7.5.0.56
TensorRT: 5.1.6.1
Vision Works: 1.6.0.500n
VPI: NOT_INSTALLED
Vulcan: 1.1.70

I try to make car moves by using AI methods but when I try collecting dataset this error appears:

nvidia@nvidia:~/marc$ ./collect_data.sh

ModuleNotFoundError: No module named ‘netifaces’
Speed : None Angle : None
Speed : None Angle : None
Speed : None Angle : None

the speed and the camera not detected, and it gives none value

I used this code source for teleporting car and collecting data
