Warmup scheduler seems not working?

Hi
In the supplementary material in your paper, you used warmup in the first 500 iterations. But I found that the learning rate keeps the same when training.

The warmup_method in your config is 'constant', don't you think it should be 'linear'?

Hi, the constant warmup assigns a smaller LR (1/3 of the original LR) for the first 500 iterations. I think the linear warmup should also be working well. I don't think the choice between constant and linear warmup will make a big difference here.
