tensorRt installation fails w cuda9.1 / cuDNN 7.0.5

Accelerated Computing GPU-Accelerated Libraries
#1

sudo apt install tesnorrt

returns

Some packages could not be installed …
… unmet dependencies:
tensorrt : Depends: libnvinfer4 (>= 4.0.2) …

and I guess it is because this is not compatible w cuda9.0
