What's need to mofidify if we use this work for another language?
I am using your work for generating Vietnamese handwriting. I added my code to create_text_data.py
elif dataset=='VNOnDB':
if mode == 'tr':
split = 'train'
elif mode == 'te':
split = 'test'
elif mode == 'val':
split = 'validation'
title = 'word' if words else 'line'
data_fol = os.path.join(root_dir, title)
label_paths = os.path.join(data_fol, split + '_' + title + '.csv')
with open(label_paths, 'rt', encoding='utf8') as f:
reader = csv.reader(f, delimiter = '\t')
next(reader)
for row in reader:
image_path_list.append(os.path.join(data_fol, split + '_' + title, row[1] + '.png'))
label_list.append(row[2])
and Lexicon to dataset_catalog.py

I generated LMDB file for training. But then when training, things got weird because the loss was negative.

Can you tell me where did I get wrong? Thank you.
Please make sure you're making correct+consistent use of character encoding (should be UTF-8 by default in py3, no?) throughout *.py files as well as other file types as used.
We made some experiments using custom characters (currency symbols) and on some cases python did not read them correctly until UTF was correctly setup.
One sanity check I would recommend is that the GT labels (i.e. one-hot vectors) look as you would expect them to during train/test iterations.
Looking forward to see Vietnamese handwriting!

@huynhtruc0309 I have some questions to ask you:
- Would you tell me if this issue was solved?
- Did you get the Vietnamese handwriting dataset on this link?
- Did the Vietnamese handwriting generation problem solve? Can you send me your code following email [email protected]? I hope to hear back from you soon.
