How to convert the ckpt model into savedmodel

In order to serve with tf-serving, the model needs to be converted into savedmodel. How to convert the ckpt model into savedmodel?

Why does not the output op have shape?

I run the following code:
print(graph.get_operation_by_name("input_image").outputs[0].shape)
print(grpah.get_operation_by_name("output_image").outputs[0].shape)

and got the following results:
(256,256,3)
()

So why is the output empty? This leads to the results that the converted saved model can not apply to triton inference server or tf-serving.
