What is the input node and output node?

I’m trying to transform the model with TF and I need to know the input node name(maybe there is only one input node like Placeholder) and output node names(maybe more than one).
Can anybody let me know it?

I’ve already answered that.

For those reading just this thread as it has a clearer title, the answer can be found here https://discourse.mozilla.org/t/quantizing-deepspeech/23130/4 and the names are

"input_node and output_node "
