What does this PR do?

Type of change: Bug fix (CI) + test coverage

Fixes onnx (torch_onnx) and onnx (diffusers), which have failed on every branch since
torch 2.14.0 was published to PyPI today (2026-09-02 13:42 UTC), and adds torch 2.14 to the unit
test matrix as the new default
so the next torch release is caught there rather than in an example job.

Root cause

Every test in those two jobs failed with:

RuntimeError: CUDNN_BACKEND_TENSOR_DESCRIPTOR cudnnFinalize failed
  ptrDesc->finalize() cudnn_status: CUDNN_STATUS_SUBLIBRARY_LOADING_FAILED

nvcr.io/nvidia/tensorrt:26.05-py3 ships cuDNN 9.22 and has no preinstalled torch, so pip
resolved the newest one — and torch 2.14 pins nvidia-cudnn-cu13==9.24.0.43. Loading 9.24
sublibraries against the image's 9.22 libcudnn.so.9 is exactly what that status reports.

last good run (08:55) first failing run (13:34)
torch 2.13.0 2.14.0
nvidia-cudnn-cu13 9.20.0.48 9.24.0.43
image cuDNN 9.22.0.52 9.22.0.52

Why only these two jobs

  • The nemo and pytorch images have a preinstalled torch that already satisfies torch>=2.8,
    so pip never resolves a new one — confirmed from the megatron job log, where torch does not appear
    in Successfully installed.
  • tensorrt:26.05-py3 has no preinstalled torch, so pip takes the newest from PyPI.
  • onnx (torch_trt) shares that image but passes throughout, because torch-tensorrt<2.13
    already holds torch below 2.14.

The changes

  1. Constrain torch only where the incompatibility is. PIP_CONSTRAINT=torch<2.14 in the example
    runner, applied when the job's image is a tensorrt one. It also covers the
    examples/*/requirements.txt loop in the same shell, which matters because nemo_automodel
    pulls torch in too. Not pinned in pyproject.toml: torch 2.14 is fine anywhere its own bundled
    cuDNN is the one loaded, so that would constrain users to work around one pinned image.
  2. Test torch 2.14. torch_214 added to TORCH_VERSIONS (torchvision~=0.29.0) and promoted to
    the unit-test default across the supported Python versions, with 2.13 demoted to the back-compat
    row. release.yml's basic unit test moves to the same default (it was still on 2.12).
    Nothing exercised 2.14 before — which is why a torch release reached us through an example
    job instead of a unit test.

Testing

  • actionlint and YAML/TOML parse clean; pre-commit clean.
  • Verified by this PR's own jobs: onnx (torch_onnx) and onnx (diffusers) reproduce the failure on
    main right now, and the new unit-3.12(torch_214, tf_latest) job is the first run of ModelOpt
    against torch 2.14.

Before your PR is "Ready for review"

  • Is this change backward compatible?: ✅ — CI-only; no source or package metadata change
  • If you copied code from any other sources or added a new PIP dependency, did you follow guidance in CONTRIBUTING.md: N/A — no new dependency
  • Did you write any new necessary tests?: ✅ — torch 2.14 added to the unit test matrix
  • Did you update Changelog?: N/A — internal CI, not user-facing
  • Did you get Claude approval on this PR?: ❌ — not yet requested

📝 Walkthrough

Walkthrough

The project now requires Torch versions from 2.8 up to, but not including, 2.14. Comments document CI failures related to cuDNN and torchvision::nms registration.

Changes

Torch dependency constraint

Layer / File(s) Summary
Update Torch dependency range
pyproject.toml
The Torch requirement changed from torch>=2.8 to torch>=2.8,<2.14. Comments document Torch 2.14 CI incompatibilities involving cuDNN and torchvision::nms registration.

Estimated code review effort: 1 (Trivial) | ~2 minutes

Merge Risk: 🟡 Moderate · up to 8c8d5

The PR globally changes the supported Torch range to <2.14, which may unnecessarily block non-TensorRT installs, while an unresolved workflow input issue leaves a potential CI command-injection risk. Merge should wait until the cap is appropriately scoped or explicitly accepted and the workflow concern is addressed.

Full details: Docstring Coverage

Explanation

No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check. Docstring coverage is scoped to functions touched by this diff. Analyzed 0 functions across 0 files. (1 skipped: 1 unsupported.)

Full details: Security Anti-Patterns

Explanation

PASS: The PR changes only pyproject.toml. It adds no modelopt or example Python files and introduces no torch.load, numpy.load, trust_remote_code, eval, exec, or # nosec patterns. The dependency edit changes the existing torch&gt;=2.8 constraint to torch&gt;=2.8,&lt;2.14; it does not add a new PIP dependency. Therefore, none of the explicit security failure conditions applies.

Full details: Title check

Explanation

The title identifies the TensorRT example-image Torch constraint, which is a main part of the change. However, it incorrectly states that Torch 2.14 becomes the unit-test default; the change constrains Torch to versions below 2.14.

…rrt images

torch 2.14.0 was published to PyPI today and broke the onnx and diffusers
example jobs: nvcr.io/nvidia/tensorrt:26.05-py3 ships cuDNN 9.22 and has no
preinstalled torch, so pip resolved 2.14, whose bundled cuDNN is 9.24. Every
test failed with CUDNN_SUBLIBRARY_LOADING_FAILED. Constrain torch there, where
the incompatibility actually is, rather than in pyproject where it would reach
users for whom torch 2.14 is fine.

Nothing exercised 2.14 before this: the nemo and pytorch images have a
preinstalled torch that already satisfies torch>=2.8, so pip never resolves a
new one, and torch_trt is held below 2.14 by torch-tensorrt<2.13. Promote it to
the unit-test default across the supported Python versions and demote 2.13 to
the back-compat row, so the next torch release is caught by unit tests rather
than by an example job.

pre_commit_all installs .[all,dev-lint] with a fresh resolve, so it picks up
torch 2.14. In that env torchvision::nms fails to register, which makes
modelopt's transformers plugin unavailable, so ModelOptHFTrainer is never
exported and the ARGUMENTS.md hook dies on an unguarded import of it.

Sets UV_CONSTRAINT as well as PIP_CONSTRAINT: nox builds the session venv with
uv, and uv ignores PIP_CONSTRAINT. Verified with `uv pip compile` -- torch
resolves to 2.14.0 with PIP_CONSTRAINT alone and to 2.13.0 with UV_CONSTRAINT.

The plugin itself is fine on torch 2.14 -- reproduced locally in a venv with
.[all,dev-lint] on torch 2.14.0 and transformers 5.14.1, where it imports
cleanly because torchvision is not pulled in at all. The failure needs a
mismatched torchvision present, so this is an environment constraint rather
than a source fix.
