[CRITICAL] <MultiROICropper::process> MultiROICropper.cxx::L50 EventImage2D size 0 <= target channel 0 about larcv HOT 6 CLOSED

ha, yes when available I suggest we look at complaints made from code, like we should respect compiler error/warning messages :)

from larcv.

Duh. The producer name for the images were wrong.

from larcv.

The error message is explicitly complaining about zero size image array. So I don't think it has to do with ROI for this particular error message. This is either the producer label being wrong or serious bug that made empty Image2DArray.

from larcv.

I think the image2d producer name is wrong

Created TTree image2d_tpc_tree... makes me thing ssnet is looking for "tpc" producer for EventImage2D.

in pyana_in*.cfg I changed the image producer to run on my own input-to-tagger LArCV file

dang @drinkingkazu beat me

heh. sorry guys, this shouldn't have been an issue. I thought I would do a better job of tracking bugs as a way to provide hints for future users. But this issue is just due to my stupidity.
