code problem

[depcco]

@CM-BF HI,I have a question about a piece of code. In GOOD\networks\models\GINS, there is code as shown in the image. Based on my understanding, self.convs.extend is used for the assignment operation, so the returned self.convs should be None. However, when I debugged it, it actually returned a specific network structure. Could you tell me why this happens? Thank you so much.
