After the rebase onto current main, this is missing --validate --parity — launchTestListCheck in jenkins/L0_Test.groovy:3823 now runs --l0 --qa --waive --validate --parity (added by #17975). Neither flag needs a wheel or a GPU: --validate is an AST walk over the test sources and --parity is set logic over the lists this run already produced, so both belong in the CPU pod.

They do depend on the collection results being trustworthy, though, so this can't just be flag-copied — see the check_test_list.py comment about --continue-on-collection-errors.

--extra-index-url adds the CPU channel alongside PyPI; pip then resolves torch by version across both indexes and will usually pick the default-PyPI wheel, which is the CUDA build. So the "avoids the ~2 GB CUDA download" comment likely doesn't hold. Use --index-url https://download.pytorch.org/whl/cpu (with the pytest/psutil deps coming from a separate --extra-index-url to PyPI), or pin torch==<ver>+cpu explicitly.

Separately, torch>=2.12.0 floats free of the pinned version in requirements.txt; a future torch release can break this pod without any change in the repo.

Add type annotations to the modified functions.

Use -> bool for ipc_nvls_supported, -> int for get_mpi_world_size, and annotate install_python_dependencies as def install_python_dependencies(llm_src: str, install_wheel: bool = True) -> None:.

This keeps the changed helpers compliant with the repository's function-annotation guideline.

The exit-code mapping is backwards. Verified with pytest 9.0.3:

pytest --co -q                                   -> 2  (INTERRUPTED)
pytest --co -q --continue-on-collection-errors   -> 1  (TESTS_FAILED)

Collection errors bump session.testsfailed; --continue-on-collection-errors only suppresses the Interrupted raise, so the run ends as TESTS_FAILED (1). Exit 2 is what you get without the flag — and also on a real interrupt (KeyboardInterrupt, shouldstop). As written this still fails on the case you meant to tolerate, and silently passes an aborted run.

Same in verify_qa_test_lists and verify_waive_list. If you do want to tolerate collection errors, key off something explicit (parse the --co output, or check invalid_tests.json) rather than an exit code that means "some tests failed".

Note also that #17975 has since landed on main and made this check=True meaningful beyond this function: load_collectable_entries() treats every entry in l0_test.txt/qa_test.txt as collectable because these three calls hard-fail otherwise. Relaxing them here makes --parity compare accepted against a set that includes uncollectable entries, so false_confidence is always empty and the gate passes vacuously. Please rebase and decide explicitly how the CPU path interacts with --parity (see the review comment).

This fallback applies to every pytest run of the integration suite, not just the CPU-only collection pod. In a real test job with a half-broken install, the import now succeeds silently and get_mpi_world_size() returns 1 — so multi-GPU tests at conftest.py:1544 get skipped instead of erroring, and skip_no_nvls skips everything. A silently-green run is worse than an ImportError.

Gate it on something the collection-only path sets explicitly, e.g.

if os.environ.get("TRTLLM_TEST_LIST_CHECK_ONLY") == "1":
    def get_mpi_world_size(): return 1
    ...
else:
    from tensorrt_llm.bindings import ipc_nvls_supported
    ...

and export it from checkTestList() in jenkins/L0_MergeRequest.groovy.

from tensorrt_llm.bindings import ipc_nvls_supported
from tensorrt_llm.llmapi.mpi_session import get_mpi_world_size
except (ImportError, ModuleNotFoundError):
# tensorrt_llm is not installed (e.g. pytest --collect-only from a source
# checkout without a built wheel). Provide no-op stubs so collection
# succeeds; these functions are only called during test execution, not
# during collection.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Do not mask import failures from an installed TensorRT-LLM package.

Catch only ModuleNotFoundError for tensorrt_llm or its missing build-time submodule. The current ImportError handler also catches errors raised inside an installed module. The fallback then reports NVLS as unsupported and MPI size as 1, so CI can silently skip coverage instead of reporting a broken installation.

Proposed fix 
 try:
     from tensorrt_llm.bindings import ipc_nvls_supported
     from tensorrt_llm.llmapi.mpi_session import get_mpi_world_size
-except (ImportError, ModuleNotFoundError):
+except ModuleNotFoundError as exc:
+    if exc.name is None or not exc.name.startswith("tensorrt_llm"):
+        raise
     # tensorrt_llm is not installed ...

As per coding guidelines, catch the narrowest exception possible.
