Issue installing on ubuntu 18.04

[andcarnivorous]

I am trying to install TensorRT on a Ubuntu system, I have installed CUDA 10.1 installed from source as well as cuDNN 7.6.

This is the output I get when I use the command cmake .. -DTRT_LIB_DIR=$TRT_RELEASE/lib -DTRT_BIN_DIR=pwd/out

You need to have TensorRT already before trying to build this library. $TRT_RELEASE should resolve to the location where you have it installed.

Hi @andcarnivorous,

@dflamand is correct - you need to first install the full TensorRT release before trying to add/upgrade the Open Source components that this repository contains.
