Hsin-Fang Chiang added a comment - 02/Feb/18 9:30 AM Looks good to me to suppress these instances, and new tickets can be opened if more instances are found.

Paul Price added a comment - 01/Feb/18 3:01 PM I propose that although what I've done has not dealt with every instance of those warnings in the entire stack, it is a good start on this problem and cleans up HSC processing which was the original driver of this ticket. I myself have no reason to go much further, and so if we believe more cleanup is warranted I suggest we accept what I've done and start a new ticket (preferably with a list of file and line number) for any further instances that need to be dealt with. Hsin-Fang Chiang , would you mind reviewing this work?

Paul Price added a comment - 01/Feb/18 2:54 PM I added the numpy.errstate context manager in a bunch of places identified from a recent processing of HSC SXDS i-band observations, which I believe also covers the above. This won't catch every instance of those warnings, but it catches the dominant ones I see in HSC processing. At least some of the warnings coming from tests will be a distinct population that I have not caught here, and I do not propose to deal with them myself. Jenkins is running along nicely (but doesn't include one more case in meas_alg). price@pap-laptop:~/LSST/afw (tickets/DM-11776 %=) $ git sub commit e2971d31a4af7e00f0bee347699fdfc9af51174f (HEAD -> tickets/DM-11776, origin/tickets/DM-11776) Author: Paul Price <price@astro.princeton.edu> Date: Thu Feb 1 14:15:19 2018 -0500   rgb: suppress NAN warnings   python/lsst/afw/display/rgb.py | 9 +++++---- 1 file changed, 5 insertions(+), 4 deletions(-)     price@pap-laptop:~/LSST/meas_algorithms (tickets/DM-11776=) $ git sub commit 996418b6539b348ef933f9628f1004ca2868e3a7 (HEAD -> tickets/DM-11776, origin/tickets/DM-11776) Author: Paul Price <price@astro.princeton.edu> Date: Thu Feb 1 13:55:23 2018 -0500   suppress numpy warnings about NAN /software/lsstsw/stack/Linux64/meas_algorithms/13.0-18-gc4ad422+4/python/lsst/meas/algorithms/objectSizeStarSelector.py:400: RuntimeWarning: invalid value encountered in less bad = numpy.logical_or(bad, width < self.config.widthMin) /software/lsstsw/stack/Linux64/meas_algorithms/13.0-18-gc4ad422+4/python/lsst/meas/algorithms/objectSizeStarSelector.py:401: RuntimeWarning: invalid value encountered in greater bad = numpy.logical_or(bad, width > self.config.widthMax) /software/lsstsw/stack/Linux64/meas_algorithms/13.0-18-gc4ad422+4/python/lsst/meas/algorithms/matcherSourceSelector.py:126: RuntimeWarning: invalid value encountered in greater return sourceCat.get(self.fluxKey)/sourceCat.get(self.fluxSigmaKey) > self.config.minSnr   .../lsst/meas/algorithms/astrometrySourceSelector.py | 3 ++- python/lsst/meas/algorithms/matcherSourceSelector.py | 3 ++- python/lsst/meas/algorithms/measureApCorr.py | 3 ++- python/lsst/meas/algorithms/objectSizeStarSelector.py | 18 +++++++++--------- python/lsst/meas/algorithms/sourceSelector.py | 9 +++++---- 5 files changed, 20 insertions(+), 16 deletions(-)     price@pap-laptop:~/LSST/ip_isr (tickets/DM-11776=) $ git sub commit b1a803cbae5fb8b5b12c9bfea81769d73a634d96 (HEAD -> tickets/DM-11776, origin/tickets/DM-11776) Author: Paul Price <price@astro.princeton.edu> Date: Thu Feb 1 14:11:14 2018 -0500   suppress numpy NAN warnings We don't care, and they clutter the output.   python/lsst/ip/isr/isrFunctions.py | 15 ++++++++------- python/lsst/ip/isr/isrTask.py | 31 ++++++++++++++++--------------- 2 files changed, 24 insertions(+), 22 deletions(-)     price@pap-laptop:~/LSST/pipe_tasks (tickets/DM-11776=) $ git sub commit 3a70a1dbff64d392e1f95be588ea252e929fe6dd (HEAD -> tickets/DM-11776, origin/tickets/DM-11776) Author: Paul Price <price@astro.princeton.edu> Date: Thu Feb 1 14:25:04 2018 -0500   assembleCoadd: suppress numpy NAN warning   python/lsst/pipe/tasks/assembleCoadd.py | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-)
