Several questions about micro TVM

[sho]

Thank you very much for your answers.

There are actually two GraphExecutor implementations in TVM: one for the C++ Runtime and one for the C Runtime. Sorry for this confusion.

Oh, ok. I should have noticed that GraphExecutor written in C is in crt. Looking though the contents of tvm/src/runtime/crt, I can create a C project on IDE with the source code here and the outputs from tvm.relay.build + SoC(or MCU) initialization code right?

@areusch

could you clarify this sentence? I think you meant to say something different in the second “micro TVM.”

Apologies for my mistakes and confusing you. I wanted to say

“I understood that the key difference is micro TVM uses C runtime and TVM uses C++ runtime, and the latter may not work on MCUs for the moment.”

But this might not always be the case since as for Host-driven execution, which requires rpc server/client communication, the scripts for this are in

tvm/src/runtime/rpc at main · apache/tvm

https://github.com/apache/tvm/tree/main/src/runtime/crt/microtvm_rpc_common https://github.com/apache/tvm/tree/main/src/runtime/crt/microtvm_rpc_server

and they are written in C++ right?

I think before I dive into micro TVM, I should begin with TVM so that I will have clear understanding of the difference between TVM and micro TVM.

We’ll be releasing some roadmaps for microTVM and TVM as a whole ~next month.

Thank you for your release information. I’m looking forward to its release.

Yes, the microtvm-blogpost-eval does explain the approach, but unfortunately it’s a bit out of date. We should have a new tutorial at some point soon that uses Project API. I’d also suggest you look for the Arduino tutorial coming up at TVMCon. Apologies for lacking documentation here.

Ok, that’s fine as long as it works anyway. Also I’ll try to run the Arduino tutorial when it’s published. Thank you for your suggestion.
