Bug Description

CONTRIBUTING.md explicitly references Python 3.14 as the target build environment. However, installing dependencies from requirements.txt on a Python 3.14 environment fails during pip install.

Cause

• kokoro strictly pins numpy==1.26.4.
• NumPy 1.26.4 does not have pre-built wheel (.whl) binaries available on PyPI for Python 3.14.
• pip falls back to building NumPy from source using Meson/Ninja, which fails on standard Windows machines that lack installed Visual Studio C++ (MSVC) build tools.

Recommended Fix

• Update CONTRIBUTING.md to recommend Python 3.11 or 3.12 for the development environment setup.
• Alternatively, evaluate if kokoro dependency pins can be loosened to allow newer NumPy versions that publish Python 3.14 wheels.
