Description
Bug Description
TestTorchTensorRTModule::test_get_layer_info fails with AssertionError: False is not true on H100 GPUs across multiple CUDA 13.x versions. The failure is consistent across r13.2.0 and r13.1.1.
Environment
- GPU: H100
- Arch: x86_64
- CUDA: 13.2.0 / 13.1.1
- OS: Ubuntu 24.04
- cuDNN: 8.9.7.29
- TensorRT: 10.16.0.59
- TensorRT (Myelin): 2.17.78+7
- CASK: 5.16.17+1
- Python: 3.12
- Package: qa_tar_py3.12
Failing Test
FAILED api/test_classes.py::TestTorchTensorRTModule::test_get_layer_info - AssertionError: False is not true
Reproducible Configurations
| GPU | CUDA | OS | Result |
|---|---|---|---|
| H100/x86_64 | r13.2.0 | Ubuntu 24.04 | FAILED |
| H100/x86_64 | r13.1.1 | Ubuntu 24.04 | FAILED |
Steps to Reproduce
- Run on an H100 with CUDA 13.x and the environment listed above
- Execute:
pytest api/test_classes.py::TestTorchTensorRTModule::test_get_layer_info
Expected Behavior
test_get_layer_info should return valid layer information and the assertion should pass.
Additional Context
The test suite overall is healthy (46 passed, 1 skipped), with only this single test failing. The error message (False is not true) suggests get_layer_info() may be returning an empty or falsy result on CUDA 13.x, possibly due to an API change or missing support in the newer CUDA/TensorRT stack.

Research direction
Start by running pytest api/test_classes.py::TestTorchTensorRTModule::test_get_layer_info on an H100 with the listed CUDA 13.x environment. Inspect the failing assertion and get_layer_info() behavior in api/test_classes.py, then verify that the test returns valid layer information and the full relevant test set passes.
