Halide AutoSchedule Error

[Gager-Git-life]

How to use autoscheduler in the latest version of halide?

##I modified the code in the auto_schedule section of app/onnx/model.cpp by referring to the halide documentation
std::string auto_schedule(const HalideModel &pipeline) { // Generate a schedule for the pipeline. Halide::Target tgt = Halide::get_host_target(); // auto schedule = pipeline.rep->auto_schedule(tgt); Halide::AutoschedulerParams autoscheduler_params = Halide::AutoschedulerParams("Adams2019"); auto schedule = pipeline.rep->apply_autoscheduler(tgt, autoscheduler_params); return schedule.schedule_source; }

##When I compile and test, the following error occurs
`PYTHONPATH="bin/host/:$PYTHONPATH" python3 -m unittest model_test.py -v
test_empty_model (model_test.ModelTest) ... ok
test_model_with_initializer (model_test.ModelTest) ... ok
test_scalars (model_test.ModelTest) ... ERROR

I can confirm that app is currently busted. I have opened a PR to fix in #7673

Yes, thank you. It compiles and passes now.
