RuntimeError: set_storage_offset is not allowed on a Tensor created from .data or .detach().

错误提示信息：

If your intent is to change the metadata of a Tensor (such as sizes / strides / storage / storage_offset)
without autograd tracking the change, remove the .data / .detach() call and wrap the change in a `with torch.no_grad():` block.
For example, change:
    x.data.set_(y)
to:
    with torch.no_grad():
        x.set_(y)

出错的代码：feature.data.t_(), target.data.sub_(1)

按照提示修改

with torch.no_grad():

   feature.t_(), target.sub_(1)

就可以啦o(*￣▽￣*)ブ
