I'm wondering if it's possible to use C backend for Relay frontend. I'm trying to compile Relay models to MicroTVM targets by using `target="c"` in `tutorials/tune_relay_x86.py`, and I'm running into this obscure trace during tuning:
``` Traceback (most recent call last): [bt] (8) /home/jsteward/work/tvm/build/libtvm.so(tvm::NodeFunctor<void (tvm::runtime::ObjectRef const&, tvm::ir::StmtFunctor<void (tvm::Stmt const&)>*)>::operator()(tvm::runtime::ObjectRef const&, tvm::ir::StmtFunctor<void (tvm::Stmt const&)>*) const+0x52) [0x7f1e1fab0802] [bt] (7) /home/jsteward/work/tvm/build/libtvm.so(tvm::codegen::CodeGenC::VisitStmt_(tvm::ir::Block const*)+0x1c) [0x7f1e1faa277c] [bt] (6) /home/jsteward/work/tvm/build/libtvm.so(tvm::NodeFunctor<void (tvm::runtime::ObjectRef const&, tvm::ir::StmtFunctor<void (tvm::Stmt const&)>*)>::operator()(tvm::runtime::ObjectRef const&, tvm::ir::StmtFunctor<void (tvm::Stmt const&)>*) const+0x52) [0x7f1e1fab0802] [bt] (5) /home/jsteward/work/tvm/build/libtvm.so(tvm::codegen::CodeGenC::VisitStmt_(tvm::ir::Store const*)+0x317) [0x7f1e1faab217] [bt] (4) /home/jsteward/work/tvm/build/libtvm.so(tvm::codegen::CodeGenC::PrintExpr[abi:cxx11](tvm::Expr const&)+0x19b) [0x7f1e1fab709b] [bt] (3) /home/jsteward/work/tvm/build/libtvm.so(tvm::codegen::CodeGenC::PrintExpr(tvm::Expr const&, std::ostream&)+0x99) [0x7f1e1faa5039] [bt] (2) /home/jsteward/work/tvm/build/libtvm.so(tvm::codegen::CodeGenCHost::VisitExpr_(tvm::ir::Broadcast const*, std::ostream&)+0x56) [0x7f1e1faba9d6] [bt] (1) /home/jsteward/work/tvm/build/libtvm.so(tvm::codegen::CodeGenCHost::PrintType(tvm::DataType, std::ostream&)+0x14a) [0x7f1e1faba57a] [bt] (0) /home/jsteward/work/tvm/build/libtvm.so(dmlc::LogMessageFatal::~LogMessageFatal()+0x43) [0x7f1e1f95b4a3] File "../src/codegen/codegen_c_host.cc", line 143 TVMError: Cannot convert type float32x64 to C type ``` I've looked around and thought that `float32x64` might be SIMD-related, but I don't have any clues on how to disable SIMD in this case. Any help would be appreciated. --- [Visit Topic](https://discuss.tvm.ai/t/c-target-for-relay/6696/1) to respond. You are receiving this because you enabled mailing list mode.
