These directories now consume tens of gigabytes. These changes
allow the source and data directories to be separate.

Also allows testing to wipe the source directory without having to re-download data.

Summary by CodeRabbit

  • New Features

    • Tutorial data, outputs, and model weights can now be redirected through environment settings.
    • Test runs use isolated directories and support configurable tutorial datasets.
    • Tutorial validation now includes metric comparisons alongside screenshot checks.
  • Bug Fixes

    • Improved detection of test timeouts, hangs, and unsuccessful nightly runs.
  • Documentation

    • Updated supported Python versions to 3.11–3.13.
    • Added guidance for relocating tutorial and test data.
  • Tests

    • Added coverage for configurable paths, cached datasets, and baseline metrics.

Walkthrough

The PR centralizes tutorial data, output, and weight paths. It adds isolated test fixtures, metric baselines, runtime limits, Python 3.13 support, and stricter GPU, nightly, and worktree setup workflows.

Changes

Tutorial infrastructure and validation

Layer / File(s) Summary
Shared path contracts and configuration
tutorials/parameters_*.py, tests/test_parameters_base.py, data/*
Adds environment-configurable data, output, and weight roots with separate test subdirectories. Updates dataset parameter classes, cache documentation, ignore rules, and path-resolution tests.
Tutorial path migration
tutorials/tutorial_*.py
Routes tutorial datasets, outputs, PCA artifacts, and model weights through test-aware parameter accessors.
Test fixtures and baseline validation
src/physiotwin4d/test_tools.py, tests/conftest.py, tests/test_tutorials.py, .gitattributes
Adds JSON and CSV metric comparison, generated DirLab, Duke heart, and Chest-CT fixtures, required-data handling, test-duration enforcement, tutorial metric checks, and Git LFS rules for PNG baselines.

CI and environment support

Layer / File(s) Summary
Python and dependency configuration
pyproject.toml, docs/*.rst
Updates supported Python versions to 3.11–3.13, adjusts dependency constraints and tooling targets, and documents the new requirements.
CI and nightly execution
.github/workflows/README.md, .github/workflows/ci.yml, .github/workflows/nightly-health.yml
Adds Python 3.13 coverage, explicit CUDA checks, targeted GPU tests, persistent nightly directories, per-test time limits, and a final failure gate.
Worktree dependency installation
utils/setup_feature_worktree.py
Passes the virtual-environment interpreter explicitly and stages build tools and CUDA 13 PyTorch packages before editable all-extra installation.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: ⚪ Minimal · up to e000b

The PR separates tutorial source, data, and output directories to reduce storage pressure and improve test isolation. The only remaining issue is a minor dependency-history comment correction, which has no runtime impact or merge-blocking risk.

Use _TUTORIAL_WEIGHTS for the lung model bootstrap.

Tutorial 9 runs with PHYSIOTWIN_RUNNING_AS_TEST and writes this checkpoint under _TUTORIAL_WEIGHTS. This code checks the full-run repository directory instead. On a clean test run, it runs Tutorial 9 and then fails the assertion at Line 957. If a full-run checkpoint exists, Tutorial 10 still does not receive the required test-mode checkpoint.

-        model_dir = (
-            _REPO_ROOT / "tutorials" / "network_weights" / "physicsnemo_mgn_lung_motion"
-        )
+        model_dir = _TUTORIAL_WEIGHTS / "physicsnemo_mgn_lung_motion"

Pluggy official changelog 1.1.0 new-style hook wrappers 1.2.0 wrapper=True yanked

💡 Result:

In pluggy, the "new-style" hook wrappers were introduced to provide a simpler alternative to the existing hookwrapper=True wrappers [1][2]. Key details regarding the releases and the wrapper mechanism are as follows: 1.1.0 (YANKED): This version introduced new-style hook wrappers, which were implemented as generator functions [1][2]. However, the implementation relied on implicit detection of these generators. This caused breakage in downstream projects (such as conda) that used generator functions for other purposes, leading to unintended behavior and errors (e.g., TypeError: 'NoneType' object is not iterable when the generator did not return a value) [3]. Consequently, release 1.1.0 was officially yanked from PyPI [4][5]. 1.2.0: To rectify the issues caused by the implicit detection in 1.1.0, pluggy 1.2.0 was released [1][2]. This version requires an explicit wrapper=True designation in the @hookimpl() decorator to define a new-style hook wrapper [1][6]. This change ensures that the new-style wrappers are only enabled when explicitly intended by the developer, maintaining compatibility with existing codebases that might use generators for other reasons [7][3]. In summary, new-style hook wrappers are now fully supported, but they must be marked with wrapper=True within the @hookimpl() decorator to avoid the issues that necessitated the yanking of version 1.1.0 [1][6].

Correct the Pluggy version-history comment.

pluggy>=1.2.0 is required because conftest.py uses pytest.hookimpl(wrapper=True). Pluggy introduced new-style wrappers in 1.1.0, but that release was yanked. Pluggy 1.2.0 added the explicit wrapper=True designation. Keep the dependency declaration unchanged.
