I use the pre-trained model you gave (ShanghaitechB),and get a pretty good results ,but I use the example you gave about train.py, and try to train the dataset (ShanghaitechB). But I get totally different results. Your pre-trained get good results, but my model can not get good results. the esitimated_map are full of yellow . It can not locate anyone! No matter which epoch I choose(100,500,1000),results are same. Full of yellow blocks

I don't know which example you are talking about. My example in the readme file is not meant to be used to train any neural network or any dataset in particular, but only to instruct on which parameters one can provide to the script. Training a neural network is not trivial task and it takes a while to experiment with hyperparameters.
