Resnet Shortcut Condition

[BlueAnthony]

想请问一下这行 if stride != 1 or in_planes != self.expansion*planes: 这两个条件看起来不可能单独存在 两个条件一定会同时符合，所以判断其中一个似乎就够了？ 也就是说，不会有下列几种可能：

1. stride != 1 但 in_planes == self.expansion*planes
2. stride == 1 但 in_planes != self.expansion*planes 还是我哪里理解错了？

You are right, if you just leave it as if stride !=1: , you will get the same results as ResNet only uses a stride of 2 when wanting to change the number of filter kernels.
