Hi peter
I took the original ipynb file and coded into a py file, ran it in spyder and had the same messesage re kernel restarting.
I then tried as suggested : python fifar10.py in a linux terminal and it just froze. I may just be because I am running it on an older (2009) desktop. it might be getting ready to die. I’m going to leave this for awhile.
Thanks for your help
Clive
