Question: ARL module: BasicBlock——channel?

[HeConnor]

Hello,
I felt confued about your BasicBlock module:

class BasicBlock(nn.Module):
    expansion = 1
    def __init__(self, inplanes, planes, stride=1, downsample=None, alpha =0.001):
        ...
    def forward(self, x):
        ...
        out = out + residual + self.alpha * attention * residual

if in_channels != out_channels, the last line can running?
residual: inplanes, out: planes

Looking forward to your reply. Thanks.
