oops, missed this delivery failure. The ttf file is too large to attach because it contains asian characters. I can upload it somewhere if you're interested, but I plan on training a model for my own edification. Original message below:
This is awesome, thank you so much! What hyperparameters did you use for training? number of pages? epochs? Which model did you start with? your file seems smaller than other eng.traineddata files.
