Open Source Vizier: Distributed service framework for blackbox optimization and research.
Project description
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 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.
- PyGlove: For large-scale evolutionary experimentation and program search using OSS Vizier as a distributed backend.
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.requirements-test.txt
: Libraries needed for testing code.
Check if all unit tests work by running run_tests.sh
after a full installation. OSS Vizier requires Python 3.10+, while client-only packages require Python 3.7+.
