validation speed

I just did validation. I found there were only 28 pictures . However it read the model for each picture.
It seems to be a little time-unfriendly.

I have just added prediction script (pred_list.py) to make predictions for a list of images using single loaded model. I will update the script to make batched predictions in order to increase the speed even further.

thx. But recently I tried to make predictions, it ran out of my memory and swap.
I have 32G memory and 32G swap. And I only gave 4 pictures to pred_list.
So once I ran pred_list.py, my server stoped.
