adversarial example for single channel (greyscale) caffe models

[rajasekharponakala]

hi,
i'm using the adversarial-example-caffe scripts to test my single channel model.

However, i tried changing caffe.io.load_image(image_path, color=False) and set the channel_swap uncommented, but no use, any help?
This is the traceback, that i'm getting:
Traceback (most recent call last): File "adv.py", line 129, in <module> make_n_test_adversarial_example(img, net, transformer, epsilon, label_index=label_index) File "adv.py", line 40, in make_n_test_adversarial_example attack_hwc = transformer.deprocess(data_blob, transformed_img + adversarial_noise[0]) File "/home/raja/Documents/rs/caffe/python/caffe/io.py", line 174, in deprocess decaf_in += mean ValueError: non-broadcastable output operand with shape (224,224) doesn't match the broadcast shape (1,224,224)
