[Help] there is no "default" function in mod.so

[wanggujin]

envrionment:
llvm-project: release/19.x (build from source)
tvm: v0.18.0 (build from source)
python: 3.10.12
wsl: ubuntu22.04

I compiled a model through below command:
python3 -m tvm.driver.tvmc compile --target "llvm" --input-shapes "input:[1,3,224,224]" --output resnet50.tar --model-format "onnx" resnet50.onnx

but, no default function in the mod.so generated.

then GetFunction("default") return a nullptr, the line gg=de(dev) crashed.

i also tried add --model-name "default" in the compile command, but it's useless.

But, if i use python script like below，the mod.so generated is fine and the inference through c++ is fine too.
`import onnx
import tvm
import tvm.relay as relay

onnx_model = onnx.load("/tmp/resnet50.onnx")

input_name = "input"
shape_dict = {input_name: [1,3,224,224]}
mod, params = relay.frontend.from_onnx(onnx_model, shape_dict)
target = tvm.target.Target("llvm")

with relay.build_config(opt_level=3):
module = relay.build(mod, target=target, params=params)
module.export_library("mod.so")`

I don't know what's the difference, can anyone help ?
