在程序运行结束后，将会自动地打印出profile report。在下面的profile report中，可以看到 `GpuMemCpy Summary`中给出了2项数据传输的调用耗时。在OP执行过程中，如果输入Tensor所在的设备与OP执行的设备不同，就会发生`GpuMemcpySync`，通常我们可以直接优化的就是这一项。进一步分析，可以看到`slice`和`crop_tensor`执行中都发生了`GpuMemcpySync`。尽管我们在程序中设置了GPU模式运行，但是框架中有些OP，例如shape，会将输出结果放在CPU上。

再次观察profile report中`GpuMemCpy Summary`的内容，可以看到`GpuMemCpySync`已经被消除。在实际的模型中，若`GpuMemCpySync` 调用耗时占比较大，并且可以通过设置`device_guard`避免，那么就能够带来一定的性能提升。
