A Python library for distributed asynchronous hyperparameter optimization over complex search spaces.
Hyperopt is a Python library for distributed asynchronous hyperparameter optimization, designed to efficiently search complex parameter spaces in machine learning models. It automates the tuning process across real-valued, discrete, and conditional dimensions, reducing manual effort and improving model performance. The library supports parallel execution via Apache Spark and MongoDB, enabling scalable optimization for research and production environments.
Machine learning researchers, data scientists, and engineers who need to optimize model hyperparameters efficiently, especially those working with high-dimensional search spaces or requiring distributed computing capabilities.
Developers choose Hyperopt for its ability to handle awkward search spaces with mixed parameter types, its support for distributed asynchronous optimization, and its implementation of advanced algorithms like TPE and Adaptive TPE, which often outperform grid or random search in complex scenarios.

Supports parallel evaluation using Apache Spark and MongoDB, enabling scalable hyperparameter search across clusters, as highlighted in the features and documentation for efficient resource utilization.
Handles real-valued, discrete, and conditional dimensions, accommodating complex parameter configurations that other libraries might not support, as demonstrated in the example code with hp.choice and hp.uniform.
Implements Tree of Parzen Estimators (TPE) and Adaptive TPE, which are more efficient than random search for high-dimensional spaces, as described in the algorithms section for varied optimization strategies.
Designed to incorporate future Bayesian optimization algorithms like Gaussian processes, indicating a forward-looking design that can adapt to new research, as mentioned in the philosophy.
The README explicitly states that Bayesian optimization algorithms based on Gaussian processes and regression trees are not currently implemented, limiting its appeal for users needing these advanced methods.
Setting up parallel execution requires configuring external systems like Apache Spark or MongoDB, which adds overhead and complexity, especially for teams not already using these technologies.
Documentation is partly hosted on a wiki and partly elsewhere, making it harder for users to find consistent and up-to-date information, as noted in the quick links section.
