I'm training Tesseract 3 for the digital-7 font, and I'm getting some errors in the output (from stderr):

APPLY_BOXES: boxfile line 35/I ((735,7860),(737,7890)): FAILURE! Couldn't find a matching blob

And

APPLY_BOXES: Unlabelled word at :Bounding box=(7523,-910)->(7549,-906)

What do they mean?

The command line I'm using is:

tesseract eng.digital-7.exp0.tif eng.digital-7.exp0 nobatch box.train

Double check your .tif file character spacing: the first error could be caused by two characters being too close, and producing one single bounding box (see also this thread).

The second error is a consequence of the first one, I suppose.
