📝 Walkthrough

Walkthrough

This PR refactors the project's dependency management system by migrating from inline dependencies in pyproject.toml to a dynamic, file-based approach using requirements.txt with custom setuptools build logic to handle environment-specific dependency resolution across different platforms and PyTorch versions.

Changes

Cohort / File(s)	Summary
CI/CD Workflow Triggers .github/workflows/lint.yml, .github/workflows/tests.yml, .github/workflows/multi-gpu-e2e.yml	Updated pull_request and push path filters to watch requirements.txt instead of pyproject.toml for triggering workflow runs.
Nightly Test Workflow .github/workflows/tests-nightly.yml	Replaced explicit pip install step for nightly Hugging Face packages with sed rewriting of requirements.txt entries to use @main GitHub branches before standard dependency installation.
Dynamic Dependency Resolution setup.py, src/setuptools_axolotl_dynamic_dependencies.py, requirements.txt	Introduced new dependency management infrastructure: requirements.txt with 78 pinned dependencies, setup.py with torch version detection and conditional filtering logic, and custom setuptools_axolotl_dynamic_dependencies module implementing platform- and torch-version-aware BuildPyCommand for dynamic dependency resolution at build time.
Project Configuration pyproject.toml	Restructured to mark version, dependencies, and optional-dependencies as dynamic; removed 168 lines of inline dependency declarations; added packaging==26.0 to build requirements; configured setuptools to use dynamic dependency module; removed [tool.uv] section and build dependencies.
Package Manifest MANIFEST.in	Added requirements.txt and setuptools_axolotl_dynamic_dependencies.py to package artifacts; removed VERSION file; added recursive inclusion of \*.py files under axolotl package.
