Error following ML tutorial

Hi,

I am following this tutorial: https://www.digitalocean.com/community/tutorials/how-to-perform-neural-style-transfer-with-python-3-and-pytorch#step-2-—-running-your-first-style-transfer-experiment

I am having the same problem as posted in the comments.

Originally, the images from this snippet pasted into Jupyter:

content_image = Image(‘{}/images/content/venice-boat.jpg’.format(workingdir)) style_image = Image(‘{}/images/21styles/starry_night.jpg’.format(workingdir)) display(content_image) display(style_image)

were not showing also, but I finally realised this was becasue the Jupyter notebook was created by user science, so home was different to root home, so I setup again in science home and I get the images etc working.

However, when it comes to the point of trying the first style transfer, I get the rror posted in the comments. Here is is:

---
