About the re-implementation of Layernorm

Hi @lucidrains ,

Thanks for the implementation of Uniformer. After checking the code, I found that you have re-implemented the layernorm operation in the following. https://github.com/lucidrains/uniformer-pytorch/blob/78397000e647fd4035a7fa2bede999d59d4c3ded/uniformer_pytorch/uniformer_pytorch.py#L13-L23

I wonder if there are any differences between your re-implementation and the official code provided by PyTorch (i.e., torch.nn.Layernorm(dim) ).

Looking forward to your reply. Thx.

Pretrained weights

Did you pretrain the uniformer on any of the benchmark datasets? (Kinetics, something-something, ...) If you did, would you be able to share the state dicts?

Thanks in advance!
