How to run 4 python object detections from 4 sources at the same time and display in one window?

Hi,

I have terrible experience of installing deep-stream…
Is there a proper instruction of installing 6.1? And run your example?
I could only found 5.0.1 installation guide…
https://docs.nvidia.com/metropolis/deepstream/5.0.1/dev-guide/text/DS_Quickstart.html
Oh, I was looking for posenet instead of object detection I mean.
And it loop back what I did :<, Any complete installation guide for “deepstream_pose_estimation”? - Intelligent Video Analytics / DeepStream SDK - NVIDIA Developer Forums

Thanks.
