Issue Description

I've installed Realsense, then installed the python wrapper, by running "pip install pyrrealsense2". I have run the example 'python-tutorial-1-depth.py' which works without any problem but when trying to run any other example I get this error: $ python opencv_viewer_example.py Traceback (most recent call last):

File "/home/rover/librealsense/wrappers/python/examples/opencv_viewer_example.py", line 45, in frames = pipeline.wait_for_frames() RuntimeError: Frame didn't arrive within 5000

You cannot use pip install pyrealsense2 when dealing with ARM processor, you can try use conda instead, conda install -c conda-forge librealsense=2.54.2=py39*

make sure create python env first and activate the env, try to use python3.9
