> Exit Code 137 on CodaLab when submitting PNG results

Hello everyone,

I'm encountering an issue with my recent submission on CodaLab for a segmentation task, and I have some more information that might help clarify the problem.

I submitted a single ZIP file containing segmentation masks (png format) in separate sequence folders. The total size of this zipped file is only 9.8 MB. My submission failed with the following metadata:

elapsedTime: 38.69649314880371
exitCode: 137
ingestionExitCode: 0

I also found an error message which shows a progress bar:
0%| | 0/30 [00:00

Based on this progress bar and my understanding of the DAIVS evaluation process (specifically, the script at https://github.com/davisvideochallenge/davis2017-evaluation/blob/master/evaluation_codalab.py), I believe the initial file and folder assertions may have passed. The error seems to be occurring at the very beginning of the evaluation loop, likely when the system is trying to process the first sequence out of 30.

The exitCode: 137 typically indicates a memory issue. I'm struggling to understand why this would happen with a small 9.8 MB file, especially during the initial stages of evaluation. It's difficult to imagine that unzipping or loading the first few files would exceed CodaLab's memory limits.

Could there be a specific issue with how CodaLab handles this type of evaluation process, or is the memory limit on the worker much lower than expected? Any insights would be greatly appreciated.

Thank you!
