# Adapting your training script to use the SMDDP collective operations
<a name="data-parallel-modify-sdp-select-framework"></a>

The training script examples provided in this section are simplified and highlight only the required changes to enable the SageMaker AI distributed data parallelism (SMDDP) library in your training script. For end-to-end Jupyter notebook examples that demonstrate how to run a distributed training job with the SMDDP library, see [Amazon SageMaker AI data parallelism library examples](distributed-data-parallel-v2-examples.md).
