Deepstream python code - Failed in mem copy (Segmentation fault)

[junshengy]

On JP6.2, using nvvideoconvert to copy data from the GPU to the CPU causes a similar problem, but I’m not sure if this is the same as your problem. Please provide your pipeline. In addition, please open a new topic to discuss your problem.

The following topic provides workaround.

Hi @kranok, thanks a lot for pointing this issue out, and we will be fixing it in the uncoming release. Currently, you can try the below pipeline first as a WAR.
