Issue Description
Hello all 

librealsense Installing pyrealsense2 on MacOS?

For me I hade to do
import pyrealsense2.pyrealsense2 as rs I apologize I wasn't active here for a long time I tested my code (Python 

librealsense module 'pyrealsense2' has no attribute 'pipeline'

Hi @tRosenflanz  Many thanks for your suggestion I wrote the following script that can perhaps be made available to other users 

librealsense IMU data stream (Python)

You could find bounding boxes on the RGB aligned to depth image use the rs.pointcloud processing block to generate vertices and crop it to the ROI: 

librealsense POINT CLOUD OF A PREDEFINED REGION USING PYREALSENSE2

If you have multiple versions of python on your machine:
From python/readme.md:

Note: To force compilation with a specific version on a system with both Python 2 and Python 3 installed

Issue Description
On Linux kernel 4.19.5 errors are generated when some commands are sent to camera in too quick succession

librealsense xioctl(UVCIOC_CTRL_QUERY) Device or resource busy errors with kernel 4.19.5

it seems like repeated calls to rs2::playback::resume and rs2::playback::pause crash the program Here is the minimal code to replicate the issue 

librealsense Playback from bag files - direct access to frames by index

I have a very similar issue except that I have only one D435 camera When I open realsense viewer for the first time it works perfectly
