why train batch_size = 1 , pad = 0 and how to predicct?

[Li-Lai]

Thank you for sharing the code. I have some questions, could you give me some advice?
Q1: Why batch = 1 in train.prototxt? The training process is very slow. I change this param, but there is no change in cuda momery, why?
Q2: Error occured when pad = 1 ( in layer conv4), but pad = 0 is ok, why? pad in darknet was setted 1.
**Q3:**How to use your code to predict images?
Look forward to your reply!
