Unable to open camera when running simple_camera.py with Python version 3.7.5

[daniellm19]

Describe the issue Unable to open camera when running simple_camera.py with Python version 3.7.5 using VSCode.

What version of L4T/JetPack L4T/JetPack version: 4.6.1

What version of OpenCV OpenCV version: 4.1.1.2 (although some seem to be 3.2.0 when I use the command: "dpkg -l | grep libopencv")

Python Version Python version if applicable: 3.7.5

To Reproduce Steps to reproduce the behavior:

1. Power the Jetson Nano
2. Attach RPi V2 camera
3. Clone this repo
4. Run the simple_camera.py file

Expected behavior A Gstreamer window pops up which shows the camera working, like it does for python 2.7.17

Additional context

1. I have a ton of different installations and overall, it's kind of a mess. Locating the root issue might be rather problematic.
2. I have used a command that removes python from the computer so that I could install the 3.7 version, what issues might this have caused? Well I needed to at least reinstall pip, who knows what else it did.

python 3.6.9 has the same problem. But when run on python 2.7 .17, it works.

Can anyone help me with this issues. Simple_camera.py works with 2.7 but when I run it python3 (3.8) it errors out saying not able to open camera.

Appreciate if you can help me with this issues. This is on Nvidia Jetson Nano.

I am using python3.8 and I am getting ImportError: cannot import name '_gi' from partially initialized module 'gi' (most likely due to circular import) (/usr/lib/python3/dist-packages/gi/init.py)
