I created 171 output images from the validation set, PNG format, of total size 75 MB, and compressed them into a ZIP archive.
My submission fails with "BadZipFile: file is not a Zip file" error thrown by the "zipfile" package.
However, when I place only 60 of the images in the ZIP (30 MB), my submission succeeds. So, there seems to be a size limit. Can it be avoided?
I also get an evaluation metric back when I submit just a few images in the ZIP file. Is that the intended functionality? How is the I/U computed if no values are reported for most of the images?

Regarding your first issue: your files seem to be unnecessarily big - most of the solutions do not exceed 10M in size in total (You may compare the file size of your submission vs the ground truth in the training data)
Regarding your second issue: Good catch - we'll fix it soon. Thanks for your report.

Posted by: jinghuang @ April 13, 2018, 9:09 p.m.Thank you. I was able to submit my results by compressing more aggressively.
On the other hand, it is impossible in practice to compress random noise to the size of the average submission, nor even the outputs of some basic algorithms applied to this problem, which give results with very fine features.
