Hi
Could you please explain the meaning of 'stage' for me in more detail? Is it not used in the entire Res2Net network？
type: 'normal': normal set. 'stage': first block of a new stage.

The normal block is the exact res2net block, and the stage block is the res2net block without shortcut inside bacause the feature shape changes for each block of a new stage.

另外还有一个问题就是，为什么对于stype=='stage‘的时候不用加上前一小块的输出结果，而是直接 sp = spx[i]呢？

因为输入输出特征的尺寸不一致，所以没法直接加起来
