Retrain the Pretrained Model in Deepstream

I want to retrain the Pre-trained object detection model which is provided in the deepstream.
The path to the model is as follows:

/opt/nvidia/deepstream/deepstream-5.1/samples/models/Primary_Detector

The files it contain are as follows:
cal_trt.bin, labels.txt, resnet10.caffemodel, resnet10.caffemodel_b1_gpu0_fp16.engine, resnet.prototxt

I want to retrain my model with my custom images.
Please guide me the steps for the same.

Thanks

You may find NVIDIA TAO can help you. It was previously called the NVIDA transfer learning toolkit.

At the bottom of the page there are some resources with some examples. I found the GTC session quite helpful:
