13. def initNNContext(): SparkContext

14. def initNNContext(appName: String): SparkContext

    Creates or gets a SparkContext with optimized configuration for BigDL performance.

    Creates or gets a SparkContext with optimized configuration for BigDL performance. The method will also initialize the BigDL engine.

    Note: if you use spark-shell or Jupyter notebook, as the Spark context is created before your code, you have to set Spark conf values through command line options or properties file, and init BigDL engine manually.

    appName

    name of the current context

    returns

    Spark Context

15. def initNNContext(conf: SparkConf): SparkContext

    Note: if you use spark-shell or Jupyter notebook, as the Spark context is created before your code, you have to set Spark conf values through command line options or properties file, and init BigDL engine manually.

    conf

    User defined Spark conf

    returns
