null files _images_train, _images_test created

[newuserfath]

After executing data_loader.py, the pickle files _images_train and _images_train are blank files. So, train_txt2im.py when executed, fails with the error : File "train_txt2im.py", line 25, in
_, images_train = pickle.load(f)
EOFError: Ran out of input

Please help
