Fixes #2015

Summary

  • Move development dependencies to a uv dependency group
  • Add a reproducible uv.lock with the configured cutoff date
  • Add make lock
  • Run development commands through uv run --frozen
  • Update CONTRIBUTING.md and CLAUDE.md for the new workflow

Testing

  • make lock passes
  • make format-check passes
  • make type-check now completes and reports five existing type-checking errors in unrelated files
  • make install-minimal currently fails due to an existing NumPy 1.18.1/Python 3.12 compatibility issue

Summary

  • Migrated development workflows to a reproducible uv.lock setup.
  • Updated Makefile targets, CI workflows, and documentation to use frozen uv commands.
  • Raised the minimum Python version to 3.8 and moved development dependencies into uv groups.
  • Added type casts and typed test helpers for static-check compatibility.

Validation

  • make lock and make format-check pass.
  • make type-check reports five existing unrelated errors.
  • make install-minimal remains blocked by NumPy 1.18.1 incompatibility with Python 3.12.

This is not the same logic anymore. Previously it was:

  1. delete the venv
  2. create a new venv
    Now we're also installing all the dependencies (including extras). So this needs to be addressed.

Thanks for the work! I think I will have to take this over, since we will need to also fix a few things in the overall dependency handling. Might touch a bit too many things in the code base for a first contribution (but don't worry, once we merge the commits will still be associated with you as well!).

📝 Walkthrough

Walkthrough

The project adopts uv-managed environments, lockfile-based dependency groups, and Makefile-driven setup and tests. CI and release workflows use pinned uv tooling. Documentation reflects the new commands. Python support now starts at 3.8, with several static typing fixes.

Changes

UV dependency and workflow migration

Layer / File(s) Summary
Python and dependency-group contract
pyproject.toml
Python support changes to 3.8+. Dependencies move into uv dependency groups with Python 3.8 resolution constraints.
UV Makefile commands
Makefile
The Makefile adds uv-based installation, testing, formatting, lock validation, packaging, notebook, CLI, and distributed-test targets.
CI test workflow integration
.github/workflows/test.yml, .github/workflows/test_code_format.yml, .github/workflows/test_minimal_deps.yml, .github/workflows/test_setup.yml
CI uses pinned uv setup, caching, concurrency cancellation, centralized environment configuration, and Makefile targets.
Notebook, release, and scheduled workflows
.github/workflows/check_example_nbs.yml, .github/workflows/release_pypi.yml, .github/workflows/weekly_dependency_test.yml
Notebook, release, and weekly dependency workflows use uv and Makefile commands. PyPI credentials use environment variables.
Developer documentation
CLAUDE.md, CONTRIBUTING.md, README.md, docs/README.md
Documentation describes locked uv environments, dependency groups, lockfile updates, and Makefile or uv run --frozen commands.
Static typing adjustments
lightly/loss/ibot_loss.py, lightly/models/modules/masked_vision_transformer_timm.py, lightly/models/resnet.py, lightly/transforms/gaussian_blur.py, tests/utils/test_optim.py
Tensor and image values receive explicit casts. The optimizer test adds typed parametrization helpers.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to eafd9

The new development workflow can expose credentials, rewrite the committed lockfile, alter a contributor’s staging area, and cause documentation or lint checks to fail; the PR is not merge-ready until these bounded workflow and documentation issues are fixed or explicitly accepted.

test-notebooks leaves regenerated notebooks staged in the developer's index.

Limit the single-command claim to CI install targets.

install-dev is also an install-* target, but the Makefile runs two commands for it: uv sync --frozen ... and uv run --frozen pre-commit install. Change this text to say “CI install targets” or explicitly exclude install-dev, so the documented contract matches the Makefile. The supplied Makefile context at Lines [135-137] shows both commands.

Proposed wording
-Every install target is a single `uv` command; never layer extra packages on top of an
-installed environment.
+Every CI install target is a single `uv` command; never layer extra packages on top of

Deferred review follow-up: the type-check job installs no extras, so mypy checks timm/matplotlib-using code as Any. Switching it to install-maximal-extras closes that gap but may surface new mypy errors, so it's better as its own PR.

206-207: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Keep install-latest from rewriting uv.lock.

uv sync --upgrade --reinstall can update uv.lock. A local make install-latest can replace the cutoff-based lock with current releases. Later frozen commands can use that lock, and make lock-check can fail.

Use a temporary lockfile and environment, or restore uv.lock after the sync.

uv sync command so it performs the upgrade and reinstall using a temporary
lockfile and environment, or restores uv.lock afterward, ensuring the
repository’s cutoff-based uv.lock remains unchanged while preserving the
existing installation behavior.

In `@docs/README.md`:
- Around line 4-7: Update the documentation build instructions around make
install-dev so Sphinx runs through the project’s uv environment, using uv run
--frozen for make html-noplot or wrapping the Sphinx invocation in
docs/Makefile; ensure the documented build uses the pinned environment rather
than relying on an activated or global installation.

Run the documentation build inside the uv environment.

make install-dev runs uv sync but does not activate .venv. docs/Makefile invokes sphinx-build directly, so make html-noplot can fail in a clean shell or use a different global Sphinx installation. Use uv run --frozen, or update docs/Makefile to wrap the Sphinx command.
