I got the following error:
RuntimeError: one of the variables needed for gradient computation has been modified by an inplace operation
with anomaly detection enabled, the last line of “traceback of the forward call that caused the error” is
num = (1 + 2 * c * xy + c * y2) * x + (1 - c * x2) * y
Traceback (most recent call last):
Error detected in MulBackward0. y has the same shape as the variable modified. If I understand this correctly, it seems the error is in ‘* y’. I don’t understand how ’ * ’ could modify ‘y’ inplace.
BTW c is a scalar tensor, and this multiplication is broadcasted.
Hope this is enough information. Thanks in advance.
