修改解包张量时出现错误。
import torch
a1, a2 = torch.tensor([1,2], dtype = torch.float64)
b = torch.rand(2, requires_grad = True)
a1 += b.sum()
此代码产生以下错误：
RuntimeError: A view was created in no_grad mode and is being modified inplace with grad mode enabled. This view is the output of a function that returns multiple views. Such functions do not allow the output views to be modified inplace. You should replace the inplace operation by an out-of-place one.
但是，当我分别创建 a1 和 a2 时，没有收到该错误，如下所示：
a1 = torch.tensor([1], dtype …
