TensorFlow SavedModel is a serialized model format that preserves a trained model for later consumption by model-serving components. In distributed training, export it once from the chief worker rather than writing competing copies from every worker. section 9.2.2
A reliable SavedModel export requires:
- Mounting persistent storage because Kubernetes Pods recycle their files after distributed training completes. section 9.2.2
Distributed export path
A two-worker TFJob mounts /trained_model, passes /trained_model/saved_model_versions/2/ as saved_model_dir, and writes the final SavedModel from the chief worker.
