# EquivalentSubGraphProto
# The equivalent_subgraph is a field in GraphProto
# We specify the inputs and outputs, such that an alternative route
# can be specified in the computation graph
# This way, multiple equivalent subgraph (potentially overlapping) can be stored in the model, each independent and not interfering
repeated equivalent_subgraph {
    # This can call an op, or a local function. This allows code reuse by now storing the actual function body in the proto message
