After reading the relevant documentation, I still have some questions:
- Relay.analysis:
- Why is there only a
post_order_visitwhich gives us a DFS order of the nodes? why would any other kind of ordered visit not needed or not wished? - Concerning
detect_feature, what exactly are these features? are they ones used for AutoTVM? (AFAIK AutoTVM works at the Tensor Expression level, so I am not sure if I misunderstood something) - Concerning

I seem to get different has values for the samerelay.expr, if I rerun the program. Why would the hash function not have a predetermined random_seed so that the hash values don’t change? Could you elaborate in how this function is normally used? and when is it necessary?
