title: Deplearning4j on Spark pipeline; Recurrent Neural Network program slow downs when added to spark pipeline
body: <p>I created a RNN program which creates an RNN model, trains it and predicts using the model using deeplearning4j. It runs with a good speed(30 minutes)but when it is added to the spark pipeline, it takes about 10 hours to run.Can you give me reason for that?</p>
