When submitting I get the error message: "Missing entries for IDs ID_035535, ID_009309, ID_022367, ID_026292, and ID_021577".
I double checked and these IDs are contained in my submission-File. Does anyone have a clue due to what reason this is?
Fix: df.to_csv(path, index = False)
Hello, If you MERGED the training data sets, you probably lost all rows with null values + some of the info. Try concatenating instead
I have verified that all IDs and corresponding predictions are present in the DataFrame df. The issue has been resolved by using df.to_csv(path, index=False) to save the submission file correctly without the default index column.
