I was trying to follow the instructions for the following TensorFlow demo, where style of an art is transfered to another image:
I successfully installed TensorFlow and the other things. But when i tried to run
'python evaluate.py --checkpoint ./rain-princess.ckpt --in-path <path_to_input_file> --out-path ./output_image.jpg',
my access was denied.

Can anyone shed light as to why this occurs? I am still quite new to this.
