I looked through the script and it kept saying 'could not install python 2 libraries' then 'could not install python 3 libraries'. It didn't give any more information than this, it just said if problem persists go to forums.pimoroni.com for support.
Maybe I missed something so here is the entire script.
Sorry for the long post...
