Iam just wondering what your submissions looks like. From the train dataset, I can see that there are 68 unique ids and if we are to predict their respective 2 weeks then we will end up 68*2 unique ids in the sub file which is in the shape (136,2) is that so with your submission files?
The submission file should have 370 rows (excluding the titles) and 2 columns
Ooh Thanks, I intially had a problem with unique_ids=train['ID'].nunique()
It was intially displaying 68 unique Ids but now it is displaying 185 which is now fine.
