报错如下：

[Error]: The context is empty.
Check whether acl.rt.set_context or acl.rt.set_device is called.

Solution: 1.Check the input parameter range of the function. 2.Check the function invocation relationship.

参考网上博客，在调用pytorch代码之前，我们需要显式设置npu设备，torch.npu.set_device(device)。其中device只要是device对象或者字符串都行，与普通pytorch用法一致。
