About validate code

[catisthebest]

Dear Doug,
when I read your code, I have a question, hope u can help me. thanks a lot.
In train_ggcnn.py file's validate（） function. when you store the model's val_loss, and you use the code below:
results['loss'] += loss.item()/ld
my question is why we should divide ld in there?
because I found you do not do the same thing in the train（） function. you divide the batch_idx in the train() function.
I don't understand what causes the difference.

could u help me？ thxxxxxx!!
