Python SDK for Tora ML experiment tracking platform

Tora Python SDK — Developer Guide

Private repository for the Tora Python SDK. This document describes how to set up the development environment, run tests, and contribute changes.

Prerequisites

• Python 3.11–3.13
• A virtual environment tool (venv/pyenv)
• Optional: pre-commit installed locally

Setup

# Create and activate a virtualenv
python -m venv .venv
source .venv/bin/activate

# Install dev dependencies
pip install -e ".[dev]"

# (Optional) enable pre-commit hooks
pre-commit install

Fast Iteration

• Run full test suite: pytest -q
• Run a single file: pytest tests/test_wrapper.py -q
• Lint and autofix: ruff check . --fix
• Clean artifacts: make clean

Coverage reports are written to htmlcov/ and coverage.xml.

Project Structure

• tora/_client.py: Core client (experiment create/load, logging, buffering)
• tora/_wrapper.py: Global convenience API (e.g., setup, tmetric, tresult)
• tora/_http.py: Minimal HTTP client and exceptions
• tora/_validation.py: Input validators
• tora/_types.py: Typed aliases and small data types
• tora/__init__.py: Public exports and __version__
• tests/: Unit tests (HTTP calls are mocked; no network required)

Development Notes

• Public metric API:
  • Use Tora.metric(name, value, step=None) for training metrics.
  • Use Tora.result(name, value) for final results (metadata handled internally).
  • The global wrapper exposes tmetric(...) and tresult(...). tlog is internal only.
• Input validation must go through validators in tora/_validation.py.
• Keep changes small and focused; update or add tests alongside code.
• Avoid adding new dependencies unless necessary.

Versioning and Changelog

• Bump version in tora/__init__.py (__version__).
• Document changes in CHANGELOG.md using Keep a Changelog format.

Release checklist (internal):

• Update README and examples as needed.
• Ensure pytest -q passes locally.
• Ensure ruff check . is clean (or run with --fix).
• Build wheel: python -m build --wheel
• Optionally validate: twine check dist/*
• Publish (internal/private): twine upload dist/* or use make pub-wheel.

Environment Variables (for manual runs)

• TORA_API_KEY: API key if talking to a live backend.
• TORA_BASE_URL: API base URL (defaults to the configured value in _config.py).

Tests mock the HTTP layer; neither variable is required to run tests.

Examples

Lightweight sanity check snippet (no network; just validates shape):

from tora import Tora

t = Tora("exp-local", url="https://example/exp-local")
t.metric("accuracy", 0.95, step=1)
t.result("best_accuracy", 0.95)
t.flush()
t.shutdown()

For a real run against an API instance, prefer using the wrapper:

from tora import setup, tmetric, tresult, shutdown

setup("dev-experiment", api_key="...", workspace_id="...")
tmetric("loss", 0.5, step=1)
tresult("best_acc", 0.95)
shutdown()

Makefile

• make help — list available targets
• make build-wheel — build wheel in dist/
• make publish-test — upload to TestPyPI
• make publish — upload to PyPI
• make pub-wheel — build, check, publish, clean

This is a private repo; use publish targets only for internal registries.
