hello!
when I run the code :python test.py --alpha=./test_data/alpha/1.png --rgb=./test_data/RGB/1.png
always appear the follow error:

Traceback (most recent call last):
File "test.py", line 47, in
main(parse_arguments(sys.argv[1:]))
File "test.py", line 16, in main
saver.restore(sess,tf.train.latest_checkpoint('./model'))
File "/usr/local/lib/python2.7/dist-packages/tensorflow/python/training/saver.py", line 1557, in restore
raise ValueError("Can't load save_path when it is None.")
ValueError: Can't load save_path when it is None.
could you help me how to solve it? thank you!
