我看到这个代码的帖子(虽然我在很多其他帖子中看到过这个解决方案)是这样的:https://www.dlology.com/blog/how-to-convert-trained-keras-model-to-tensorflow-and-make-prediction/

The post where I have seen this code(although I have seen this solution in many other posts) is this: https://www.dlology.com/blog/how-to-convert-trained-keras-model-to-tensorflow-and-make-prediction/
