Maxpool in shortcut is redundant

[liorkad3]

In the Bottleneck_IR_SE , the shortcut layer of Maxpool is always with kernel=1 and stride=1. So the layer is useless.
Am I missing something?

This happens in the last bottleneck only, where depth and channels are both the same and stride is not set (so defaults to 1), right?
As far as I know it's only a single occurrence in the model and maybe libtorch automatically optimises for it.
Otherwise, try:

        if in_channel == depth:
            if stride == 1:
                self.shortcut_layer = Identity()
            else:
                self.shortcut_layer = MaxPool2d(1, stride)
