> It seems it has something to do with the actual string you're sending on
the command line. It is not strictly a bug in tvmc at this point. Can you
please file an issue so that we can investigate that?
I didn't change anything, I still used the command:
python -m tvm.driver.tvmc compile --target "llvm" --output
compiled_module.tar resnet50-v2-7.onnx
