file missing the file X_train_256_v2.npy can't be build?

[YUN-XIAO-MO]

sir,I'am trying to run eyenet-2018,here is my running series:

resize_images.py → preprocess_images.py → rotate_images.py→ reconcile_labels.py → image_to_array.py

when i finished running image_to_array.py, it build a file--X_train.npy,

but when I turn to try cnn.py, I found that it needs X_train_256_v2.npy insted of X_train.npy,

but I can't find any .py file to build this file. How can I build this file?
