Image too large to learn!!

[shuang hao]

Hello everyone,

When I train models by LSTM 4.0 https://github.com/tesseract-ocr/tesseract/wiki/TrainingTesseract-4.00#fine-tuning-for-%C2%B1-a-few-characters

It showed this problem, how to solve it? Why happened? What should the pic size be?

Image too large to learn!! Size = 2608x48
Image not trainable
Image too large to learn!! Size = 2845x48
Image not trainable
At iteration 18938/35100/36699, Mean rms=0.379%, delta=0.441%, char train=1.315%, word train=2.366%, skip ratio=3.2%,  New worst char error = 1.315 wrote checkpoint.

Image too large to learn!! Size = 2704x48
Image not trainable
Image too large to learn!! Size = 2666x48
Image not trainable
Image too large to learn!! Size = 2634x48
Image not trainable
Image too large to learn!! Size = 2593x48
Image not trainable
Image too large to learn!! Size = 2593x48
Image not trainable
At iteration 18971/35200/36804, Mean rms=0.376%, delta=0.435%, char train=1.279%, word train=2.311%, skip ratio=3.4%,  New worst char error = 1.279 wrote checkpoint.

The pics is created by the shell "training/tesstrain.sh ", How to decide the size of the pic by this way???

training/tesstrain.sh  \
   --fonts_dir /usr/share/fonts \
  --lang chi_sim  \
  --linedata_only \
  --noextract_font_properties \
  --exposures "0"    \
  --langdata_dir ../langdata \
  --tessdata_dir /home/hs/tessdata/tessdata  \
  --output_dir ../tesstutorial/chi_sim
