On the inconsistency between the printed network structure and the paper

[PowerKaly]

Hello, author I added at the end of models/fasternet.py

if __name__ == "__main__":
    model = FasterNet(
        mlp_ratio=2.0,
        embed_dim=128,
        depths=(1, 2, 13, 2),
        drop_path_rate=0.15,
        act_layer='RELU',
        fork_feat=True,
    )

    print(model)

Try to print the network structure, and the result is

As you can see from here.

           (0): Conv2d(256, 512, kernel_size=(1, 1), stride=(1, 1), bias=False)

           (2): ReLU(inplace=True)
           (3): Conv2d(512, 256, kernel_size=(1, 1), stride=(1, 1), bias=False)
         )
         (spatial_mixing): Partial_conv3(
           (partial_conv3): Conv2d(64, 64, kernel_size=(3, 3), stride=(1, 1), padding=(1, 1), bias=False)
         )

It goes through two 1x1 convolutions and then 3x3. Contrary to the paper, I don't know if there is something wrong with my understanding. I hope you can give me some advice.thinks 👍 :)
