Subject Re: DML script parsing error in Spark
Date Tue, 08 Dec 2015 20:36:41 GMT
Hi Niketan,

Just sent a mail to this forum stating that this problem is solved.

I was passing wrong dimension while creating Y using ml.registerInput().
That was what creating problem.

Once I pass the right dimension it works.

Thanks for your help.

Regards,
Sourav
