TVM C++ deploy core dumped

#1

I’m going through the tutorial Deploy TVM Module using C++ API — tvm 0.12.dev0 documentation, trying to run the C++ deploy example. The demo is here <tvm_path>/apps/howto_deploy.

I run the shell script run_example.sh, unluckily, I got an error: Check failed: (f != nullptr)

Detial:

An error occurred during the execution of TVM.

  Check failed: (f != nullptr) is false:

And I try this demo with TVM version 0.10.0 and 0.11.0，both failed.

Trouble building examples on RPI4 & MacOS for Cpp

The line numbers in the error message show some evidence :slight_smile:

In your particular case, it looks like “runtime.SystemLib” or “addonesys” don’t exist. Would you like to double check?

#3

According to your advice,
I can find “runtime.SystemLib” is registed in src/runtime/system_library.cc:

TVM_REGISTER_GLOBAL("runtime.SystemLib").set_body_typed([]() {
  static auto mod = CreateModuleFromLibrary(SystemLibrary::Global());
  return mod;
});

And I also find “addonesys” in howto_deploy/lib/test_addone_sys.o:

nm test_addone_sys.o | c++filt -t

By the way, I switch my work to another Linux machine, the problem is still not solved.

Things become more strange. :joy:
