Hello. I have this error when submitting "Missing entries for IDs 08841052, 103933E1, 33476E28" but these IDs don't exist in the samplesubmission.csv and test.csv
try not to save the indexes when saving your csv file
e.g : yourdataFrame.to_csv('my_submission', index=False) # by default index in set to True by pandas
I had this issue because i've used excel. Excel automatically transform data with E ending to numbers. 1E3 will change to 1000.
Thank you for your responses. it does work with dataFrame_name.to_csv('my_submission.csv', index=False)
