Can I use a grayscale image as the style image?

Can I use a grayscale image as the style image? There seems to be a channel problem. Do you know how to deal with it?
Thank you for your help~

You will have to convert your grayscale image to 3D image as VGG takes 3 channel image as input. Also, you will have to change this line in utils.py
img = transform(img)[:3, :, :].unsqueeze(0)
