  19. def save(sc: SparkContext, path: String): Unit

    Permalink

    Save this model to the given path.

    Save this model to the given path. It only works for Item datatypes supported by DataFrames.

    This saves:

    • human-readable (JSON) model metadata to path/metadata/
    • Parquet formatted data to path/data/

    The model may be loaded using FPGrowthModel.load.

    sc

    Spark context used to save model data.

    path

    Path specifying the directory in which to save this model. If the directory already exists, this method throws an exception.
