Dear Paul and Mark,
Thank you for the suggestions. I just upgraded NVIDIA driver from 384 to
410 and the problem is solved.
Regards,

I just built from a similar situation but also went to Ubuntu Mint Tara 19
, cuda runtime 10 ( used the Nvidia web site .run version not the deb - do
not install the driver from the toolkit ) added the 410 driver from the
PPA and the system is quite happy.
I believe I ran across some information that suggests that the mixture of
Runtime 8, Cuda driver 9 and Ubuntu 16 is not a good mix. I?ll try to look
for it later if you need further information
Paul
