Install

$ pip install uniformer-pytorch

Usage

Uniformer-S

import torch
from uniformer_pytorch import Uniformer

model = Uniformer(
    num_classes = 1000,                 # number of output classes
    dims = (64, 128, 256, 512),         # feature dimensions per stage (4 stages)
    depths = (3, 4, 8, 3),              # depth at each stage
    mhsa_types = ('l', 'l', 'g', 'g')   # aggregation type at each stage, 'l' stands for local, 'g' stands for global
)

video = torch.randn(1, 3, 8, 224, 224)  # (batch, channels, time, height, width)

logits = model(video) # (1, 1000)

    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.

    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!
