mlflow.tensorflow

MLflow integration for TensorFlow.

Manages logging and loading TensorFlow models as Python Functions. You are expected to save your own saved_models and pass their paths to log_saved_model() so that MLflow can track the models.

In order to load the model to predict on it again, you can call model = mlflow.pyfunc.load_pyfunc(saved_model_dir), followed by prediction= model.predict(pandas DataFrame) in order to obtain a prediction in a pandas DataFrame.

Note that the loaded PyFunc model does not expose any APIs for model training.

mlflow.tensorflow.load_pyfunc(saved_model_dir)

Load model stored in python-function format. The loaded model object exposes a predict(pandas DataFrame) method that returns a Pandas DataFrame containing the model’s inference output on an input DataFrame.

Parameters:saved_model_dir – Directory where the model is saved. Return type:Pyfunc format model with function model.predict(pandas DataFrame) -> pandas DataFrame).

mlflow.tensorflow.log_saved_model(saved_model_dir, signature_def_key, artifact_path)

Log a TensorFlow model as an MLflow artifact for the current run.

Parameters:

• saved_model_dir – Directory where the exported tf model is saved.
• signature_def_key – Which signature definition to use when loading the model again. See https://www.tensorflow.org/serving/signature_defs for details.
• artifact_path – Path (within the artifact directory for the current run) to which artifacts of the model will be saved.
