[Bug] Runtime crash due to dtype mismatch

[duduhedangdang]

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:

OS	Ubuntu 20.04
Python	3.8.13 (conda env)

Hi @duduhedangdang, The v0.9.dev0 is too old a version with lots of deprecated components (e.g., Relay). If you want to report a bug, plz test the latest TVM version. I closed this issue. Feel free to reopen it if this bug can be reproduced in the latest version.
