報錯：

RuntimeError: one of the variables needed for gradient computation has been modified by an inplace operation: [torch.FloatTensor [544, 768]], which is output 0 of ViewBackward, is at version 1; expected version 0 instead.?

Hint: enable anomaly detection to find the operation that failed to compute its gradient, with torch.autograd.set_detect_anomaly(True).
?

解決方法：

報錯原因是因為我在搭建網絡模型時，殘差相加的代碼是這樣寫的： x += y

但是在pytorch中這樣寫會有問題， 改成: x = x+y就好了
