How would you install this on a Raspberry Pi?

[VeggieVampire]

This is as far as I get.
git clone https://github.com/kaishengtai/neuralart
cd neuralart
chmod 775 *
sudo apt-get install luarocks
./download_models.sh
sudo luarocks install inn

pi@raspberrypi:~/neuralart-master $ sudo luarocks install inn
