data.py gives me empty numpy arrays #3

Hi Edward,

Thanks for your code! It's simply amazing! I am trying to run it and adapt it for my own project.

When I call the function data.py, it creates the .npy files correctly and when I try to open and see those files, I got the following result:

array([[[[0, 0, 0, ..., 0, 0, 0], [0, 0, 0, ..., 0, 0, 0], [0, 0, 0, ..., 0, 0, 0], ..., [0, 0, 0, ..., 0, 0, 0], [0, 0, 0, ..., 0, 0, 0], [0, 0, 0, ..., 0, 0, 0]]],

All the .npy are empty and I'd say this is not good :(

Maybe you have a function to convert these numpy array files to image format?

Thanks for your help.

It requires in ../data/test and /data/train images from the original dataset. When running (data.py) the code iterates file by file in this dirs (function create_train_data), I can't imagine what the problem is. If I were you I would simply debug data.py (it's very simple code). Maybe you have some issues with opencv and it converts grayscale or int8 to 0.
