an issues about your ocr data iteration

[zzdang]

Hi,your project is cool ,but your OCR_LSTM_CTC's data iteration is very slow?
Could you update it?
Thank you very much

Hi,

Would it be possible for you to include some clarifications?
Which data iteration?

Your "Data Loading" module isn't iterative, you load image data and labels first time.
If the training dataset is big,the "images_data" in your "data loading" is hard to handle,the trainning will be very slow.......

@zzdang, this is true, this was an acceptable trade off given the small size of the IAM dataset, and to get the ability to load pre-processed images quickly.

If your dataset is larger I would recommend using the ImageFolderDataset available in Gluon that would let you load each image only when necessary.
