Fix: Fixed the Numpy 3.13 issue

[Prigoistic]

Python 3.13 on macOS ARM: NumPy fails to install (builds from source)

• Symptom: make install on Python 3.13 tries to build numpy==2.0.x from source on macOS ARM and fails with C/C++ errors.
• Status: Ragas CI currently targets Python 3.9–3.12; Python 3.13 is best-effort until upstream wheels are broadly available.

Workarounds:

1. Recommended: use Python 3.12

uv python install 3.12
uv venv -p 3.12 .venv-3.12
source .venv-3.12/bin/activate
uv sync --group dev
make check

2. Stay on Python 3.13 (best effort):

• Minimal install first to avoid heavy transitive pins:

uv venv -p 3.13 .venv-3.13
source .venv-3.13/bin/activate
uv pip install -e ".[dev-minimal]"
make check

• If you need extras, add gradually:

uv pip install "ragas[tracing,gdrive,ai-frameworks]"

• Prefer a prebuilt NumPy wheel (if available):

uv pip install "numpy>=2.1" --only-binary=:all:

If the resolver still pins to 2.0.x via transitive deps, temporarily set numpy>=2.1 locally and re-run uv sync --group dev.

3. Last resort: build NumPy locally

xcode-select --install
export SDKROOT="$(xcrun --sdk macosx --show-sdk-path)"
export CC=clang
uv pip install numpy

Safe alternate-venv tip:

• Keep your project .venv untouched and use .venv-3.12 / .venv-3.13. Avoid make install in alt envs; prefer uv commands directly. make check respects the active env via uv run --active.

Thanks for the PR @Prigoistic 🎉

It'd be better to pin numpy version in pyproject.toml: "numpy>=1.21.0,<3.0.0",

Rest, looks okay to go.

Pinned the version in the pyproject.toml file.

Please check if there any other changes needed before merging.
Cheers!
