(Minor) Warning when post-processing 2009 data #1552

Closed nikohansen closed 4 years ago

nikohansen commented 7 years ago

There is a RuntimeWarning from post-processing some of our 2009 data for which I wonder whether we should address this in some way or another?

[15:38:57] coco$ python -m cocopp /Users/hansen/svn/coco/BBOB/data-archive/data/gecco-bbob-1-24/2009/rawdata/*AMA*tgz

Post-processing (2+)
  Data consistent according to consistency_check() in pproc.DataSet
  using: /Users/hansen/svn/coco/BBOB/data-archive/data/gecco-bbob-1-24/2009/rawdata/AMALGAM_bosman_noiseless.tgz
  Data consistent according to consistency_check() in pproc.DataSet
  using: /Users/hansen/svn/coco/BBOB/data-archive/data/gecco-bbob-1-24/2009/rawdata/iAMALGAM_bosman_noiseless.tgz
  Will generate output data in folder ppdata/AMALG_iAMAL
    this might take several minutes.

There may be a small chance that it is related to #1466

With the current version (development branch), I don't see this warning showing up anymore with the above algorithms:

Looks like, this issue can be closed.
