Scoring Issue with ambient_temperature_system_failure.csv

Hello! I am trying to run the scoring algorithm on my results but I keep receiving the error "AssertionError: timestamps and anomalyScores should not be different lengths!" -- it seems like the start and end timestamp are the same for my timestamps and anomalyScores lists, but some of the GT labels (timestamps) are missing.

Do you have any insight for why scoring is failing for me? Thanks! Also attached is my results file.

It looks like your file is missing anomay_score values for the following rows:

  • 578-611
  • 1308-1354
  • 1629-1787
  • 2053-2147
  • 2397-2466
  • 5788-5816
  • 6171-6172
  • 6317-6330
  • 6562-6736

Thanks! That was indeed the issue -- my algorithm was missing rows for certain timestamps.
