// Set up the graph with the intended feeds (inputs) and fetches (outputs) for a
// sequence of partial run calls.

// On success, returns a handle that is used for subsequent PRun calls. The

// needed.
//
// On failure, out_status contains a tensorflow::Status with an error
// message. *handle is set to nullptr.
