Error when trying data2lmdb

Hi when trying to train crfasrnn with my own data, I get stuck in data preparation. I guess it could arise from malformed PNG but I do not get the solution. Any idea ?

python2.7 data2lmdb.py
3 train images
0 test images
Train images
Traceback (most recent call last):

your input image size is bigger than 500 x 500
