Lesson 4 Rossmann sub.csv ID link

what is the meaning of the IDs in the sub.csv file.

How can I see which store it is and which day.

Thanks for help.

I’m not sure what you mean. Are you talking about the sub.csv that is created in notebook lesson3-rossmann? That is the predictions done on the data from test.csv. If you open the file test.csv and the file sub.csv and compare them you can take in Id from the sub.csv file and check which is the corresponding Id in test.csv.
