Query on loss calculation in word language model

[AvisP]

In the main.py of word language model, I find that in the evaluate function the total_loss is getting multiplied by length of data

examples/word_language_model/main.py

Line 163 in ca1bd91

total_loss += len(data) * criterion(output, targets).item()

However in the train function, total_loss is not getting multiplied by length of data

examples/word_language_model/main.py

Line 194 in ca1bd91

total_loss += loss.item()

Is this proper?
