Under Ubuntu 16.04 any suggestions?

This is because you are trying to run the code on a custom painting. It seems that in the current version of the repository, pre-trained model for computing stylisation weights hasn't been included. Refer README:

Note that in the paper we trained a CNN on a dataset of 80,000 paintings collected from wikiart.org, which estimates the stylization level of a given painting and adjust weights accordingly. We will release the pre-trained model in the next update. Users will need to set those weights manually if running on their new paintings for now.

Refer #11 for more details.

One option to make the code work is to set the weights manually here instead of calling params_wikiart_genre though this will be cumbersome and may need a lot of tweaking.
