evaluate.py compute_losses?

[MathildaHwang]

Hi! Thank u for this wonderful work!
In evaluate.py-->compute_losses(self, dataloader), it seems that only one batch of data is used for evaluation.
But when it comes to loss computation,

losses = {k: sum(v) / len(dataloader) for k, v in storer.items()}

it uses len(dataloader) to average the loss. Should that be the length of element v?
I wonder if I misunderstand the above computation.
Any help will be appreciated!
