I'm sorry but I don't really understand how to find the ImageId that we need to send in the submission file, because I'm confuse, I wonder if it's just the \"default\" id that appear in the first column but why in the sample_submission.csv, it starts by the index 1 however in the test.csv, there is no column named \"ImageId\" so it's actually the default index which start by 0 so if I just predict the test file, it will create a submission where the default index column and ImageId column will start by 0.</p>\n<p>To be short :<br>\nIn the \"sample_submission.csv\" file, the default index and ImageId are shift of 1 and I can't find a ImageId column in the \"test.csv\" file, so for my own \"submission.csv\" file, I wonder what to use for the ImageId if it's just the same as the default index or something else.</p>",
