Problem description

I cannot download CRNN-CTC dataset https://github.com/PaddlePaddle/models/blob/develop/fluid/ocr_recognition/ctc_reader.py#L14. Sever resets connection. I already retried on different networks and machines with the same result. Can you upload the file somewhere else? What is this file? Can I find it elsewhere?

Command run

python ctc_train.py

Output
