Problem with GraphDef version when running demo

[Yummy-Lee]

The following issues arise during this step：_ = tf.saved_model.loader.load(session, ['serve'], saved_model_dir)

Converting GraphDef to Graph has failed. The binary trying to import the GraphDef was built when GraphDef version was 440. The GraphDef was produced by a binary built when GraphDef version was 778. The difference between these versions is larger than TensorFlow's forward compatibility guarantee. The following error might be due to the binary trying to import the GraphDef being too old: Op type not registered 'DecodeImage' in binary running on DESKTOP-K3E9O71. Make sure the Op and Kernel are registered in the binary running in this process. Note that if you are loading a saved graph which used ops from tf.contrib, accessing (e.g.) tf.contrib.resampler should be done before importing the graph, as contrib ops are lazily registered when the module is first accessed.
