Shuffling should happen after you’re done with processing a single row i.e. dividing the row into input and output features. ---

You have a map step after shuffle. Please remove it. ---

hello Balaji in the windowed dataset assignment, after shuffling step there is split step for features and labels, which does require dataset.map. I am getting value error. I followed the ungraded lab instructions for this assignment ---

The `map` step is responsible for creating a tuple of `(features, label)`. If you are unable to find the mistake, please click my name and message your notebook as an attachment. ---

hi Balaji, there was a mistake by me, I had interchange code in different line which I corrected. I have cleared the assignment. Thank you again for replying 🙂 Regards DP
