First I resubmitted it but didn’t have the entries for the images that were 0 bytes. I added those, and it still thinks I don’t have everything. My header row is exactly the same as the sample submission file, and I have the same number of lines in the file. The sample file doesn’t have a trailing new line character at the end of the file, so I even removed that and tried to submit, and it still says I don’t have all the rows.
Just in case anyone keeps submitting and getting the same score every time you might want to try saving the Python csv output as a new file and then submitting that to the grader (this fixed my glitch of getting the same score every time)
