I am following the example of SingleTimestepRegressionExample.  
I have just updated the passengers\_train\_0.csv and passengers\_test\_0  
with data like 10 20 30 40 50 60 …like passenger data .

But when running the program ,I am getting exception.

Exception in thread “main” java.lang.NumberFormatException: For input string: “10"”
