The evaluation for the competition is root mean square error (RMSE).  This measures the difference between your predicted number of paperclips and the actual number of paperclips. The actual number of paperclips is always integer; however, you may wish to predict floating-point numbers to account for uncertainty in your model.
Submission Format
You are submitting a CSV file where each row contains an id and your predicted paperclip count. The id's correspond to the file names of the images.  For example, id #1 is clip-1.png
The file should contain a header and have the following format:
id,clip_count
25001, 37.40416
25002, 37.40416
25003, 37.40416
25004, 37.40416
