Our submission works fine when tried on our local hardware using the provided runtime, but fails without explicit reason on the DD site with:
Your submission did not output the expected file so it could not be scored. This may be due to an unhandled exception or syntax error in your code. The log output may have more details.
However, there is no sign of any exception occurring in the logs.
We have a lot of preprocessing and need to create a temporary directory with preprocessed images. Could the problem be a result of too long processing or disk space shortage? If the cause was one of these two would we get explicit message about exceeding particular submission resources?
Knowing whether the error message we got covers “exceeding system resources” errors would help us to identify the source of the problem.
