# Batch Tuner on NNI¶

## Batch Tuner¶

Batch tuner allows users to simply provide several configurations (i.e., choices of hyper-parameters) for their trial code. After finishing all the configurations, the experiment is done. Batch tuner only supports the type choice in the search space spec.

Suggested scenario: If the configurations you want to try have been decided, you can list them in the SearchSpace file (using choice) and run them using the batch tuner.
