Thank you @hht
This is very useful. I have two follow up questions. 1) what is the purpose of external_mods in the LoweredOutput structure? 2) Ia m wondering if I can get more details about how the CodeGen in TVM works? I mean what is the sequence. I know it starts from Relay, and I am not sure if I understand the rest of the steps that lowers the Relay IR to target HW object code? [quote="hht, post:9, topic:6572"] ``` struct LoweredOutput { std::string graph_json; Map<std::string, IRModule> lowered_funcs; Array<tvm::runtime::Module> external_mods; std::unordered_map<std::string, tvm::runtime::NDArray> params; }; ``` And the IRModule shown above may have something to do with parallelism. And IRModule is something just like a lower function but not a module. ``` struct GraphCodegen { public: GraphCodegen() { auto pf = GetPackedFunc("relay.build_module._GraphRuntimeCodegen"); mod = (*pf)(); } ... ``` In build_module.cc, the lowered_funcs have been transformed into module.
