how to use TensorBoard?

[win5923]

hello i don't know how to add scalar to TensorBoard? I want to do this kind of topic, hoping to improve some ExpRate, but I don’t know much about lightning TensorBoard.

You can reference this line in lit_bttr.py file. Just pass your metric value to self.log function method.
For more details, you can see pytorch-lightning official logging documentation.

thank you so much~

Does this need to be added?

[Green-Wood]

You don't need to pass TensorboadLogger to Trainer, because this is the default behavior.

hello again, i want to ask what are #[b,], # [b, 1, H, W] , # [b, H, W] , # [b, l] mean? thx

[Green-Wood]

Well, these are just some shape descriptions of these tensors.
For example:

b: batch size
1: we have just one input channel
H: height of input image
W: width of input image
l: length of latex tokens

[win5923]

Excuse me, you already have batch above, why do you still need to define class batch below?

[Green-Wood]

Because different images may have different sizes, you need to collate images in one batch into a single tensor in Batch class.

Thank you very much, I see.
