Great that's a new version of the deb file I have cuda-repo-ubuntu1604_8.0.61-1_amd64.deb installed which has driver 375.39 so next will install that version an hopefully my 6.0.20 cudnn woes will go away.
So have updated the cuda deb package and now my driver is version 375.51. First notable change is I now have the 1080 ti name recognised correctly before it was called 'Graphics Device'
I have been using the tar versions
the command I found useful was
sudo cp -dR lib64/* /usr/local/cuda-X.0/lib64/
I removed the versions I was replacing first
sudo rm -i /usr/local/cuda-8.0/lib64/libcudnn*
But I still feel that because the 6.0.20 worked within the nvidia environment it’s not supported by Theano I will stick with 5.1.3 for now.
post any stack traces you may have as text so it’s possible to isolate the includes / libs thanks
Being new to ubuntu I issued the
sudo apt-get update
sudo apt-get --assume-yes upgrade
commands after installing the new deb then rebooted. Not sure if thats good form or not!!!
