Thank you for sharing the code. I have been trying to apply your code a data set. However, running the code gives the following error message:
exception_prefix='input')
File "D:\Program Files\Python\Python35\lib\site-packages\keras\engine\training_utils.py", line 138, in standardize_input_data
str(data_shape))
ValueError: Error when checking input: expected conv2d_1_input to have shape (256, 256, 1) but got array with shape (1, 256, 256)

reshape the training data

train_data = train_data.reshape(6,256,256,1)

Try setting data_format= channels_last
