Every time I copy to the clipboard something from the setup guide, it appends to the end the following text:
“Read more at: http://docs.nvidia.com/ngc/ngc-titan-setup-guide/index.html#ixzz59CXWVNnS

So I was getting errors on every line, took me a while to figure out where this was coming from. So my solution is to copy the code and paste it into a text editor, then copy & paste correctly!
