What is the difference between relay.build_module.create_executor and relay.build

Hi,

I found in the official tutorial that the method of compiling onnx and compiling mxnet models are different, where mxnet used relay.build, but onnx used relay.build_module. Does these two methods do the same thing? The example in the tutorial only shows how to dump the compiled model built from relay.build, could I dump and reload the compiled model built from relay.build_module.create_executor ?

By the way, I am also confused that - do I have to take care of the train mode and eval mode of some operators such as batch norm or dropout ?
