I want to do a pedestrian detection project with Nvidia Jetson Nano. I downloaded the jetson-inference repo. I ran Pednet with detectnet-camera.py but performance is not enough. There are examples of retraining classification networks in the jetson-inference repos but I couldn’t find an example of retraining for detection. I can not run train.py in the jetson-inference/python/training/detection. Can you tell me where to find the datasets for pedestrians? and can you tell me how to retrain pednet with these datasets via jetson?
