Bug In "Art Generation with Neural Style Transfer"

Hi, I learn a lot from your code! Thanks a lot!

I think there is a bug in the save_image function of Art Generation with Neural Style Transfer code. Since .detach() share the same memory, we should clone the input image first or the change will apply to the original image and mess the training.

Bellow is the fixed code for save_image

def save_image(path, imageO):
    # Un-normalize the image so that it looks good
    image=imageO.clone().detach()
    image = image.cpu().numpy().transpose(0, 2, 3, 1)
    image += CONFIG.MEANS
    image = np.clip(image[0], 0, 255).astype('uint8')

pretrained weights for FaceNet and Emoji data?

Hi! I have cloned your repo and tried to run the files and encountered two missing file error: when I run the FaceNet code, I found the following error indicates that the weight is missing:

---------------------------------------------------------------------------
FileNotFoundError                         Traceback (most recent call last)

    362     paths = {}
    363     weights_dict = {}

FileNotFoundError: [Errno 2] No such file or directory: './weights'

When I run the Emojify code, I found that the emoji data file seems to be missing:

---------------------------------------------------------------------------

     35     emoji = []
     36 
---> 37     with open (filename) as csvDataFile:
     38         csvReader = csv.reader(csvDataFile)
     39 

FileNotFoundError: [Errno 2] No such file or directory: 'data/train_emoji.csv'

Do you mind also upload the facenet weights as well as the emoji data to your repo, or direct me to where I can download that? Thank you very much for the help!
