fix: split training dependency profiles

[ironcommit]

Summary

Moves heavy training-only dependencies (wandb, mlflow-skinny, datasets) out of the base nmp-unsloth, nmp-rl, and nemo-safe-synthesizer-plugin packages and into optional extras, so nmp-api and other non-training installs no longer pull them in. Also loosens the wandb pin from ==0.28.2 to >=0.28.2 across all training/customizer images, now that a floor rather than an exact match satisfies the reviewed wandb-core CVE fix.

Changes

• services/unsloth/pyproject.toml: moved wandb/mlflow-skinny from base dependencies into a new [integrations] extra.
• services/rl/pyproject.toml: bumped the existing [integrations] extra's wandb floor from >=0.25.1 to >=0.28.2.
• plugins/nemo-safe-synthesizer/pyproject.toml and packages/nemo_platform/pyproject.toml: moved datasets out of base dependencies into a new [tasks] extra (and the generated bundle list).
• plugins/nemo-customizer/pyproject.toml: dropped the unused datasets/transformers base dependencies.
• docker/Dockerfile.nmp-unsloth-training and docker/rl/Dockerfile.nmp-rl-training: install nmp-unsloth[integrations] / nmp-rl[integrations] editably so the training images still get W&B/MLflow.
• docker/Dockerfile.safe-synthesizer-tasks: sync the plugin with --extra tasks to restore datasets.
• docker/Dockerfile.nmp-customizer-tasks, docker/automodel/Dockerfile.nmp-automodel-base, docker/rl/Dockerfile.nmp-rl-base, docker/unsloth/no_override_requirements.txt, docker/automodel/no_override_requirements.txt, root pyproject.toml: relaxed wandb==0.28.2 pins to wandb>=0.28.2.
• tests/unit/test_docker_workspace_slices.py: updated to assert the >= floor instead of an exact pin, and added docker/rl/Dockerfile.nmp-rl-base to the set of checked files.
• services/unsloth/tests/test_hf_trainer_callback.py: stub transformers in tests now that it's no longer a base dependency pulled in transitively.
• services/unsloth/README.md: documented the new [integrations] extra.

Type of Change

• Code change (feature, bug fix, or refactor)

Quality Gates

• Existing tests cover changed behavior — justification: tests/unit/test_docker_workspace_slices.py and services/unsloth/tests/test_hf_trainer_callback.py were updated to cover the new extras and pin changes.
• Documentation not applicable — justification: services/unsloth/README.md updated inline with the change; no other user-facing docs affected.

Summary by CodeRabbit

• New Features
  • Added optional integrations support for W&B and MLflow.
  • Added a conversion command for Pi environments to Gym-compatible formats.
  • Expanded reinforcement-learning images with Automodel and Megatron training environments.
• Improvements
  • Updated W&B compatibility to support version 0.28.2 and newer.
  • Reduced unnecessary runtime dependencies for the NeMo Customizer plugin.
  • Improved container cleanup and validation for more reliable image builds.
• Documentation
  • Updated integration, package layout, and Helm configuration references.

📝 Walkthrough

Walkthrough

The pull request updates dependency extras and W&B version floors, standardizes Docker cleanup through shared manifests, expands RL image environments, adds license-generation group support, refreshes dependency inventories, and updates related tests and documentation.

Changes

Dependency and image alignment

Layer / File(s)	Summary
Dependency and tooling contracts pyproject.toml, services/*/pyproject.toml, plugins/nemo-customizer/pyproject.toml, docker/*/no_override_requirements.txt, tools/lint/*	Optional integration and conversion extras are defined. W&B minimum versions are updated. Type-check commands use the new dependency group.
Docker environments and cleanup docker/Dockerfile*, docker/automodel/*, docker/rl/*, tests/unit/test_docker_workspace_slices.py	Docker builds install integration dependencies, prepare additional RL environments, upgrade W&B, and use shared file-removal manifests.
Runtime import and test isolation services/automodel/src/*, services/automodel/tests/*	Tokenizer loading uses runtime Transformers import. Tests detect optional Transformers availability and use explicit configuration objects.

License inventory refresh

Layer / File(s)	Summary
License generation configuration tools/nemo-platform-sdk-tools/src/*, tools/nemo-platform-sdk-tools/tests/*	License generation preserves export options, accepts dependency groups, forwards project settings, and adds license overrides.
Regenerated dependency and license inventory third_party/requirements-main.txt, third_party/licenses.jsonl	Dependency provenance, package versions, openshell metadata, and compatible license records are refreshed.

Documentation and test updates

Layer / File(s)	Summary
Documentation and artifact assertions services/unsloth/README.md, k8s/helm/README.md, e2e/test_nemo_agents_execute_job.py	Unsloth and Helm documentation reflect current configuration. Successful job validation no longer requires stderr.txt.

generate_lockfile_without_dev_dependencies and _sanitize_requirements_file to
pass the constructed command into the sanitizer. Preserve --package, --extra,
and --group arguments in the requirements header while continuing to remove
