Upgrade Python version to 3.12 across all CI/CD workflows and package requirements #322
Conversation
… requirements - Update all GitHub Actions workflows to use Python 3.12 (from 3.11, 3.9.x, 3.9, and 3.x) - Update pyproject.toml minimum Python version requirement from >=3.9 to >=3.12 - Update Python version check in test-json-schema-to-grammar.cpp from 3.8 to 3.12 - All tests passing (37/37) and build successful after upgrade Co-Authored-By: Priya Padmanabhan <[email protected]>

NumPy Compatibility Issue with Python 3.12
NumPy 1.25.0 does not have pre-built wheels for Python 3.12. I verified this by checking PyPI metadata - there are 0 wheels available for cp312. This will cause installation failures when users try to install dependencies with Python 3.12.
Recommendation: Bump numpy to a version that supports Python 3.12:
# Before
numpy = "^1.25.0"
# After (NumPy 1.26.0+ has Python 3.12 support)
numpy = "^1.26.0"Additionally, please verify that other dependencies (transformers, sentencepiece, torch) have compatible versions available for Python 3.12. You can test this with:
python3.12 -m venv .venv && source .venv/bin/activate
pip install -e gguf-py

Incomplete Python Version Updates Across Workflows
This PR updates Python to 3.12 in several workflows, but there are additional workflow files that still reference older Python versions:
.github/workflows/pre-tokenizer-hashes.yml- still at3.11.github/workflows/python-type-check.yml- still at3.11.github/workflows/python-lint.yml- still at3.11
For consistency with this upgrade, these workflows should also be updated to Python 3.12.
Additionally, this workflow uses actions/setup-python@v4 while all other updated workflows use @v5. For consistency and to pick up latest fixes, please upgrade:
# Before
- name: Setup Python
uses: actions/setup-python@v4
with:
python-version: '3.9'
# After
- name: Setup Python
uses: actions/setup-python@v5
with:
python-version: '3.12'

Python Executable Resolution Issue
The test checks for Python >=3.12 using the python command, but on many systems (especially Linux), python may not exist or may point to Python 2.x. The more reliable approach is to try python3 first, then fall back to python.
Recommendation:
// More robust version check that tries python3 first
const char *py3_check = "python3 -c \"import sys; exit(1) if sys.version_info < (3, 12) else print('Python version is sufficient')\"";
const char *py_check = "python -c \"import sys; exit(1) if sys.version_info < (3, 12) else print('Python version is sufficient')\"";
if (getenv("LLAMA_PYTHON_AVAILABLE") ||
std::system(py3_check) == 0 ||
std::system(py_check) == 0) {
// run tests
} else {
fprintf(stderr, "\033[33mWARNING: Python not found (min version required is 3.12), skipping Python JSON schema -> grammar tests.\n\033[0m");
}This ensures the test works across different environments while maintaining the new 3.12 requirement.
