Fix 3rdparty detector bugs #45

Open pmenn36 opened 4 years ago

pmenn36 commented 4 years ago

I noticed when evaluating my own detector using this process that there were two bugs that got in the way:

  1. The default NAB labels contained duplicate rows, but the output of my detector did not contain duplicates. This resulted in a length difference between the labels and the anomaly scores, which raised an AssertionError. I fixed this by adding an optional --removeDuplicateLabels flag. The default behavior remains unchanged.
  2. The anomaly scores from my output csv were being read in as strings instead of floats. I forced casting to float in sweeper.py, which does not affect the default behavior because the anomaly scores from the default detectors are correctly read in as floats anyway.

Hi,

Sorry it took a year for anyone to respond to your PR. For what its worth, I just now merged your changes for casting the thresholds to floating point numbers.

I didn't merge the stuff about duplicate records BC I've never encountered that bug. If that is a real bug and something that you still want fixed then ping me (@ctrl-z-9000-times ) and I will review and merge that as well.

Thanks!
