Experiments Module in phoenix-client

arize-phoenix-client

PyPI

New Features in Phoenix 11.7+:

• Added a new experiments property to both Client and AsyncClient for invoking experiment workflows.

• Introduced Experiments and AsyncExperiments classes with run_experiment methods supporting tasks, evaluators, dry-run mode, and metadata.

• Implemented SyncExecutor and AsyncExecutor classes for concurrent execution with built-in progress bars.

• Added RateLimiter and AdaptiveTokenBucket for intelligent handling and throttling of rate-limit errors.

Bug Fixes:

• Fixed a typo in the datasets.get_dataset_versions docstring.

Enhancements:

• Introduced a PhoenixException base class and refactored exception imports for consistency.

• Simplified rate limiter output by replacing printif with direct print statements.
