AttributeError: 'module' object has no attribute '_rebuild_tensor_v2'

pytorch报错：AttributeError: ‘module’ object has no attribute ‘_rebuild_tensor_v2’
原因：由于训练模型时使用的是新版本的pytorch，而加载时使用的是旧版本的pytorch。
解决方法：
在文件的顶部加上这段代码

import torch._utils

try:

    torch._utils._rebuild_tensor_v2

except AttributeError:

    def _rebuild_tensor_v2(storage, storage_offset, size, stride, requires_grad, backward_hooks):

        tensor = torch._utils._rebuild_tensor(storage, storage_offset, size, stride)

        tensor.requires_grad = requires_grad

        tensor._backward_hooks = backward_hooks

        return tensor

    torch._utils._rebuild_tensor_v2 = _rebuild_tensor_v2
