Vizier: Distributed service framework for blackbox optimization and research.

Open Source Vizier: Reliable and Flexible Black-Box Optimization.

Documentation | Installation | Citing Vizier

What is Open Source (OSS) Vizier?

OSS Vizier is a Python-based service for black-box optimization and research, based on Google Vizier, one of the first hyperparameter tuning services designed to work at scale.

OSS Vizier's distributed client-server system. Animation by Tom Small.

OSS Vizier's interface consists of three main APIs:

• User API: Allows a user to setup an OSS Vizier Server, which can host black-box optimization algorithms to serve multiple clients simultaneously in a fault-tolerant manner to tune their objective functions.
• Developer API: Defines abstractions and utilities for implementing new optimization algorithms for research and to be hosted in the service.
• Benchmarking API: A wide collection of objective functions and methods to benchmark and compare algorithms.

Additionally, it contains advanced API for:

• Tensorflow Probability: For writing Bayesian Optimization algorithms using Tensorflow Probability and Flax.

Please see OSS Vizier's ReadTheDocs documentation for detailed information.

Installation

To install the core API, the simplest way is to run:

pip install google-vizier

which will install the necessary dependencies from requirements.txt.

For full installation (to support all algorithms and benchmarks), run:

pip install google-vizier[extra]

which will also install the dependencies:

• requirements-jax.txt: Jax libraries shared by both algorithms and benchmarks.
• requirements-tf.txt: Tensorflow libraries shared by both algorithms and benchmarks.
• requirements-algorithms.txt: Additional repositories (e.g. Emukit) for algorithms.
• requirements-benchmarks.txt: Additional repositories (e.g. NASBENCH-201) for benchmarks.

Check if all unit tests work by running run_tests.sh. OSS Vizier requires Python 3.10+, while client-only packages require Python 3.7+.
