WOW, guys it worked. I don’t have a nvidia graphics card, just one of those intel things on the motherboard, so I ignored any references to it in QuantScientist’s notes.
While my two linux boxes are sort of old, I’m running the latest Ubuntu distribution, and it took about 30 minutes to compile and it seems to be working just fine.
I tested it operationally on some of the Python scripts from my Udemy courses and they all seem to be working.
This has been quite the week for me, yesterday tweaking a tensorflow install to run on Python3.6 and today building my own version of Pytorch
Thanks guys 
Clive
