torch中对nn.Parameters中部分参数加入噪声

Write to .data instead? [RuntimeError: a leaf Variable that requires grad has been used in an in-place operation.]

如题：当进行下述操作时，

my_adam = optim.Adam([z], lr=self.lr_shape)

# and this comes in the training loop:
loss.backward()
my_adam.step()
z[some_indices] = z[some_indices] + my_noise_tensor

报错：

RuntimeError: a leaf Variable that requires grad has been used in an in-place operation.

解决措施：

z.data[some_indices] = z[some_indices] + my_noise_tensor

或者

with torch.no_grad():
  z[some_indices] += my_noise_tensor
