### What does this PR do?
Type of change: New feature / infrastructure improvement
Follow-up to #1285 for correct CI test environment for megatron based
tests
Replaces `tox` + `tox-current-env` with `nox` for all test, lint, docs,
and wheel build sessions. The primary motivation was that
`tox-current-env` is incompatible with uv venvs in NGC containers (e.g.
NeMo's `/opt/venv`) — it picks the system Python via
`sys._base_executable` instead of the container's venv Python which has
megatron packages pre-installed.
Key changes:
- **`noxfile.py`** replaces `tox.ini` with GPU, CPU unit,
partial-install, pre-commit, docs, and wheel sessions
- **GPU sessions** use `venv_backend="none"` (run directly in container
env) and `python -m pip/pytest` to avoid PATH mismatches
- **uv** is set as the default venv backend (if available) for CPU
sessions (faster installs)
Also includes CI workflow simplifications:
- **`_pr_gate.yml`** new reusable workflow centralizing file-change
detection + linux-check wait logic (was duplicated across 3 workflow
files)
- **Collapsed pr/non-pr job pairs** into single jobs with conditional
`runs-on` in `gpu_tests.yml`, `example_tests.yml`,
`regression_tests.yml`
- **Collapsed `multi-py` / `multi-torch` / `multi-transformers`** into a
single `multi-version` matrix job in `unit_tests.yml`
- **PR path filtering** for unit test secondary jobs (multi-version,
launcher, partial-install) — skipped if no relevant files changed
- **Fixed schedule/workflow_dispatch skipping** — jobs with `needs:
[pr-gate]` were incorrectly skipped when all pr-gate internal jobs were
skipped; fixed by making the gate job always run
- **multi-version, launcher, partial-install** now also run on
`schedule` / `workflow_dispatch`
### Usage
```bash
python -m pip install nox uv # install nox and uv (once)
nox -l # list all sessions
nox -s gpu_megatron # run a GPU session (inside container)
nox -s "unit-3.12(torch_211, tf_latest)" # run a specific unit test combination
nox -s "unit-3.12(torch_211, tf_latest)" -R # force-recreate venv (e.g. after dep changes)
COVERAGE_PROCESS_START=pyproject.toml nox -s "unit-3.12(torch_211, tf_latest)" # with coverage
```
### Testing
- Ran `nox -l` to verify all session names
- Ran `gpu_megatron` session locally inside NeMo container — confirmed
it uses `/opt/venv/bin/python` correctly
- Manually triggered nightly-runs:
- Unit:

### What does this PR do?
Type of change: new feature, new example <!-- Use one of the following:
Bug fix, new feature, new example, new tests, documentation. -->
<!-- Details about the change. -->
## Summary
- Add skip-softmax sparse attention (BLASST) for diffusion models via
dedicated Triton kernels — an inference kernel with tile skipping and a
calibration kernel with vectorized multi-threshold sparsity measurement
- Add `triton_skip_softmax` method with exponential model calibration
(`scale_factor = a * exp(b * sparsity)`) and log-space fitting for
diffusion models
- Add Triton kernel backends for diffusers and LTX attention dispatch
- Fix calibration to skip RULER dataset generation when user provides
their own `forward_loop` (required for non-LLM models)
## Changes
### Triton kernels (`modelopt/torch/kernels/triton_fa.py`)
- **`_attn_fwd`**: Forward kernel with optional tile skipping — tiles
whose max attention score is far below the running softmax max are
skipped entirely (no V load, no softmax, no accumulation). Runtime
sparsity measurement via atomic counters.
- **`_attn_fwd_calibrate`**: Calibration kernel that computes full
attention while measuring how many tiles would be skipped at each of N
thresholds simultaneously. Uses per-program output buffers (zero atomic
contention) and vectorized multi-threshold comparison.
- **`attention()`** / **`attention_calibrate()`**: Python wrappers for
inference and calibration kernels.
### Kernel backends
(`modelopt/torch/sparsity/attention_sparsity/kernels/`)
- **`diffusers_triton_attention.py`**: Registers `modelopt_triton`
backend in diffusers' attention dispatch. Handles [B, S, H, D] → varlen
layout conversion, calibration/inference mode switching, thread-local
configuration, and counter accumulation.
- **`ltx_triton_attention.py`**: Patches `ltx_core.Attention` modules
for Triton dispatch with the same calibration/inference modes.
### Method
(`modelopt/torch/sparsity/attention_sparsity/methods/triton_skip_softmax.py`)
- `TritonSkipSoftmaxMethod`: Context managers for calibration (→
calibration kernel) and inference (→ forward kernel with tile skipping).
Three threshold priority levels: raw threshold > calibrated scale_factor
> static threshold.
### Calibration
(`modelopt/torch/sparsity/attention_sparsity/calibration/`)
- **`calibrator.py`**: `DynamicThresholdCalibrator` with `fit_logspace`
option — fits exponential model in log space (minimizes relative error)
for diffusion models where scale_factors span many orders of magnitude.
Records observed sparsity range for extrapolation warnings.
- **`calibrate.py`**: Skips RULER dataset when `forward_loop` is
provided; passes `fit_logspace` through from config.
### Config & conversion
- **`config.py`**: `CalibrationConfig.fit_logspace` field (default
False, recommended True for diffusion models).
`skip_softmax_raw_threshold` field for direct threshold mode.
- **`conversion.py`**: Auto-registers diffusers/LTX Triton backends on
`sparsify()`. Updated summary display.
### Example
- **`wan22_skip_softmax.py`**: End-to-end example for WAN 2.2 5B/14B
with baseline, raw-threshold, and calibrated modes. Supports runtime
sparsity reporting.
## Threshold modes
| Mode | How it works | Use case |
|------|-------------|----------|
| **Raw threshold** (`--raw-threshold -0.7`) | Passed directly to kernel
as `skip_threshold_log2` | Quick testing, sweeps |
| **Calibrated** (`--calibrate --target-sparsity 0.5`) | `scale_factor =
a * exp(b * target)`, then `threshold = scale_factor / seq_k` at runtime
| Production use with seqlen adaptation |
| **Static** (default `skip_softmax_threshold=0.1`) | `log2(lambda) *
sm_scale` | Fallback |
## Usage
```bash
# Fixed raw threshold (no calibration)
python examples/diffusers/sparsity/wan22_skip_softmax.py \
--model-path /path/to/Wan2.2-T2V-A14B-Diffusers \
--raw-threshold -0.7 \
--prompt "A cat playing piano" --output out.mp4
# With calibration (log-space fit for diffusion models)
python examples/diffusers/sparsity/wan22_skip_softmax.py \
--model-path /path/to/Wan2.2-T2V-A14B-Diffusers \
--calibrate --target-sparsity 0.5 \
--prompt "A cat playing piano" --output out.mp4
# Dense baseline for comparison
python examples/diffusers/sparsity/wan22_skip_softmax.py \
--model-path /path/to/Wan2.2-T2V-A14B-Diffusers \
--baseline \
--prompt "A cat playing piano" --output baseline.mp4

### What does this PR do?
- Add experimental support for transformers >=5.0 and remove deprecated
usages:
https://github.com/huggingface/transformers/blob/main/MIGRATION_GUIDE_V5.md
- ⚠️ For accelerate examples that used `--warmup-ratio: float`
(deprecated in 5.x), we now change it to `--warmup-steps: float | int`
which works as ratio if float but only for 5.x. For 4.x, it will error
out if float and prompt user to change back to `--warmup-ratio` or pass
an int absolute step count.
- ⚠️ Unified Hugging Face checkpoint export for quantized checkpoints
may not work for some models with transformers>=5.0 yet as it requires a
lot of fixes (e.g. change in how MoE experts are organized)
- ~Add Workaround for TRT-LLM's import of deprecated transformers
functions so trt-llm based gpu unit tests work fine. Still deployment
for models needs proper fixes directly in TRT-LLM hence llm/vlm ptq
example tests still run with transformers 4.57~
- Everything except PTQ and Export (mainly MoE) should work fine with
transformers>=5.0
- Bump min torch to 2.8 and enable 2.11 cicd testing
- NOTE: Upcoming Nemo:26.04 container comes with transformers 5.3
### Testing
<!-- Mention how have you tested your change if applicable. -->
- [x] CI/CD tests passing
- [x] Manually tested unit tests, gpu tests with transformers 4.56 and
5.4
- [x] Manually tested example tests (except trt-llm container tests)
with transformers 4.56 and 5.4

## Summary
Add `launcher/` module for submitting quantization, training, and
evaluation jobs to Slurm clusters or running them locally with Docker
via `nemo-run`. `nemo-run` is used in all `NVIDIA-NeMo/*` projects. It
supports modern YAML factory (superset of the `OmegaConf` and `Hydra`)
and it support multiple executor backends (here we use docker and slurm
mainly).
A sample YAML config `launcher/Qwen/Qwen3-8B/megatron_lm_ptq.yaml`:
```
job_name: Qwen3-8B_NVFP4_DEFAULT_CFG
pipeline:
# hf_local: path prefix for model weights and datasets.
#
# This should be a self-managed directory that mirrors the HuggingFace Hub
# hierarchy (e.g., /hf-local/Qwen/Qwen3-8B/, /hf-local/cais/mmlu/). Using
# a dedicated folder is preferred over the HuggingFace cache (~/.cache/huggingface)
# to avoid cache corruption issues with concurrent jobs.
#
# Override on CLI:
# pipeline.global_vars.hf_local=/mnt/my-models/ # use a different path
# pipeline.global_vars.hf_local="" # download from HuggingFace Hub
global_vars:
hf_local: /hf-local/
task_0:
script: common/megatron-lm/quantize/quantize.sh
args:
- --calib-dataset-path-or-name <<global_vars.hf_local>>abisee/cnn_dailymail
- --calib-size 32
environment:
- MLM_MODEL_CFG: Qwen/Qwen3-8B
- QUANT_CFG: NVFP4_DEFAULT_CFG
- HF_MODEL_CKPT: <<global_vars.hf_local>>Qwen/Qwen3-8B
- MMLU_DATASET: <<global_vars.hf_local>>cais/mmlu
- TP: 4
slurm_config:
_factory_: "slurm_factory"
nodes: 1
ntasks_per_node: 4
gpus_per_node: 4
```
### Key features
- **`launch.py`** — public entrypoint accepting `--yaml` config format
- **`core.py`** — shared logic (dataclasses, executor builders, run
loop) also used by nmm-sandbox's `slurm.py`
- **Factory system** — env-var-driven `slurm_factory` with
`register_factory()` registry
- **`<<global_vars.X>>`** interpolation for sharing values across
pipeline tasks
- **`hf_local`** global var for configurable model/dataset storage path
- **Version reporting** — git commit/branch printed at job start for
reproducibility
- **`--to-yaml`** — dump resolved config for bug reports and
reproducibility
- **Model-Optimizer symlink** — `modules/Model-Optimizer -> ../..`
(auto-created, avoids recursive submodule)
### Files
| Path | Description |
|------|-------------|
| `launcher/launch.py` | Public entrypoint |
| `launcher/core.py` | Shared dataclasses, executors, run loop |
| `launcher/slurm_config.py` | SlurmConfig + env-var factory |
| `launcher/common/` | Shell scripts (quantize, query, eagle3,
specdec_bench) |
| `launcher/Qwen/Qwen3-8B/` | Example configs (PTQ, EAGLE3 pipeline) |

### Verified
- Same YAML produces identical MMLU results via both `slurm.py` and
`launch.py`:
- Local Docker (TP=1): 0.719 (128/178)
- OCI-HSG Slurm (TP=4): 0.730 (130/178)
## Test plan
- [x] 64 unit tests (core, factory, YAML, Docker executor, Slurm
executor, Docker launch)
- [x] CI workflow added to `.github/workflows/unit_tests.yml`
- [x] Local Docker end-to-end with `python:3.12-slim`
- [x] Qwen3-8B PTQ on OCI-HSG via both launchers
- [ ] Reviewer runs: `cd launcher && uv pip install -e . pytest && uv
run pytest -v`

Fixes https://github.com/NVIDIA/Model-Optimizer/issues/217
## Summary
- Bump `requires-python` from `>=3.10,<3.13` to `>=3.10,<3.14` to
formally include Python 3.13
- Add explicit Python 3.10–3.13 PyPI classifiers for better
discoverability
- Add `py313` to tox CPU unit test and partial-install environment
matrices
- Add Python 3.10–3.13 to the `multi-py` CI matrix in `unit_tests.yml`
## Background
Python 3.13 was previously excluded by the `<3.13` upper bound. Testing
in a related repo with `--ignore-requires-python` confirmed that the
library installs and runs correctly under Python 3.13. This PR lifts the
restriction and wires up CI to verify it going forward.
## Test plan
- [ ] CI `multi-py` job passes on `py313-torch210-tf_latest-unit`
- [ ] `tox -e py313-torch210-tf_latest-unit` passes locally (requires
Python 3.13 installed)
- [ ] `tox -e py313-partial-unit-torch` passes locally
- [ ] No regressions on existing Python 3.10/3.11/3.12 matrix jobs

## Summary by CodeRabbit
* **Chores**
* Extended Python support: minimum remains 3.10; added official support
up through 3.13 (upper bound advanced accordingly).
* **Tests**
* CI and test matrix expanded to include experimental Python 3.13
coverage.
* **Documentation**
* Installation docs and changelog updated to reflect Python 3.13
support.

* Reworked GPU test infra to use a persistent distributed worker pool
with improved per-worker teardown, aggregated error reporting,
Megatron-specific cleanup, reduced GPU CI timeouts, and a small
build-system dependency change.
* **Tests**
* Converted many multi-process GPU tests to a fixture-driven distributed
runner, updating test entry points and orchestration while preserving
test logic; adjusted imports and conditional guards for several GPU
tests.

## What does this PR do?
[Short term]: Megatron based tests take a long time often resulting in
CICD timeout. Splitting megatron tests into a dedicated CICD job for
faster overall CI/CD run
[Mid/Long term]: Run all megatron gpu tests using `torchrun` instead of
`pytest` so all dist processes are already created and all individual
tests no longer need to setup and destroy their processes which adds a
lot of overhead per test

## What does this PR do?
**Type of change:** CICD infra improvement <!-- Use one of the
following: Bug fix, new feature, new example, new tests, documentation.
-->
- All example tests will now be run before PR can be merged
(onnx_ptq-bash still in gitlab as it needs internal scratch space
models. llm_eval / llm_autodeploy only run nightly to save per-PR gpu
resource)
- Users can also manually trigger specific test from
https://github.com/NVIDIA/TensorRT-Model-Optimizer/actions/workflows/example_tests.yml
- We no longer need to depend on internal gitlab infra for tests (except
nemo-megatron integration tests)
## Testing
<!-- Mention how have you tested your change if applicable. -->
- Tests run in PR and manually via workflow_dispatch
