I tried the back to back detectors example in Deepstream 4.0.1 in Jetson Nano. It is working. I tried it with a custom SSD model as primary and the given face detector as secondary and it worked. But I cant seem to run an SSD model as the secondary detector. No error occurs. But it does not perform any detection.
Below is my secondary config. My model is trained on ssd_mobilenet_v2.
