duduhedangdang opened a new issue, #18099:
URL: https://github.com/apache/tvm/issues/18099
### Expected behavior
Running the generated model with `tvm.runtime.GraphExecutor.run()` should
finish without crashing.
If the input tensor dtype is mismatched, TVM should gracefully raise a
Python‐level error instead of hitting an internal `CHECK` and aborting.
### Actual behavior
TVM aborts at runtime with an assertion failure in
`src/runtime/library_module.cc`:
