数据集

SynthText数据集，37G，太大了。
Total-Text可以使用。按照作者写的步骤，处理数据。

训练

python train_textsnake.py  example --dataset total-text --net vgg --cuda False

用了cuda有报错。

(TextSnake) xuehp@haomeiya009:~/git/TextSnake.pytorch$ nohup python train_textsnake.py  example --dataset total-text --net vgg --cuda False --start_iter 180 --resume save/pretrained/textsnake_vgg_180.pth   >> log.4.21.txt &
