How to annotate relay ops with custom compiler tag

hello i am very new to tvm , and was going through tvm’s BYOC tutorial to understand how to add custom codegen for custom h/w. Q1. although i have understood the tutorial to some extent , i am facing problems on how to build the relay graph with custom compiler tag (assuming the ops are supported by the h/w and the codegen and csource module for the h/w has been added.). is there an signature where we give compiler tag for each of the relay compute op ? ex : c = te.compute( … , Compiler = “codegenC”);

Q2. Also i would like to know how to get the C code for the “CodegenC” tutorial provided by tvm here https://tvm.apache.org/docs/dev/how_to/relay_bring_your_own_codegen.html[https://tvm.apache.org/docs/dev/how_to/relay_bring_your_own_codegen.html]. I could not find “USE_CODEGENC” option in config file , neither any example in tvm tutorials to get the C code for a given relay program.

Any help is highly appreciated. :slight_smile:
