libpng error when training with tesseract4

[kotom...@gmail.com]

hi, I have a problem.

I am training tesseract4.0 from scratch with my own image.  

when I training with yaru.game.exp0.lstmf with other 2 lstmf files, no error happens.

However, when I try to add more files for training, erro happens below. It seems like a file reading error related with libpng.

But I am so confused that File yaru.game.exp0.lstmf worked well before, why it happens when I train with more data? 

And how can I solve this problem? 

File yaru.game.exp0.lstmf page 1448 (Perfect):

libpng error: invalid distance too far back

Error in pixReadMemPng: internal png error

Error in pixReadMem: png: no pix returned

src_pix != nullptr:Error:Assert failed:in file ../../../src/ccstruct/imagedata.cpp, line 232

sh: 1: kill: Segmentation fault (core dumped)

check if your leptonica is compiled without pnd support or if your files are really png.

Did you check what I asked before?

If yes, then provide command you used and input data for it.
