AttributeError: 'NoneType' object has no attribute 'shape'

Hello, I've meet some errors when trying to use this code.
I have the same version as mentioned and I didn't change any code. But it gives me these two errors.
Exception in thread Thread-1:

Can you help with that?

I'm using the sample images in your code, and I put a print in main.py
images = [imgs_test_path + f for f in os.listdir(imgs_test_path) if f.endswith(('.jpg', '.jpeg', '.png'))]
images.sort()
print len(images)
So I'm sure the images have been read.

OMG, such a silly bug! I lost a '/' when giving the image path....
/home/usr/workspace_linux/Saliency/Image
to
/home/usr/workspace_linux/Saliency/Image/
problem solved
