Hello,

this is unexpected. can you please upload the complete installation sequence and messages? starting with dpkg -i xxxx

thanks.

Hello,

Any suggestion

I have the same problem
I’m installing TensorRT 4.0 from .deb file(nv-tensorrt-repo-ubuntu1604-cuda9.2-ga-trt4.0.1.6-20180612_1-1_amd64.deb)
cuda9.2 and cudnn 7.4 are already installed on Ubuntu 16.04
At first, I wanted to install TensorRT 5.0, but there’s no compatible version for cuda 9.2, so I use TensorRT 4.0 instead.
But got the same error.

I solved this problem.
The reason is my cuda was installed by .run file.
Reinstall cuda 9.2 with deb pack and the tesorrt 4.0 goes well.

Thanks @gehaocool for providing an update.

I came across this issue when attempting to install tensorrt5 using the .deb installer. My problem was that i had the wrong version libcudnn7.

apt list | grep cudnn
libcudnn7/now 7.4.1.5-1+cuda9.0 amd64 [installed,local]
libcudnn7-dev/unknown 7.3.1.20-1+cuda9.0 amd64
I ran
sudo apt autoremove libcudnn7
to remove the newest version, downloaded the cudnn 7.3.1 runtime deb package, and installed that version.
libcudnn7/unknown,now 7.3.1.20-1+cuda9.0 amd64 [installed,automatic]
libcudnn7-dev/unknown,now 7.3.1.20-1+cuda9.0 amd64
After this I re-attempted the tensorrt install without any problems.
              
Repros for me as of today; requested dpkg query output below the error message
johnu@ubunt-d1-16a:~$ sudo apt install tensorrt

I think you’re missing the CUDA 10.0 debian packages.  You can install the following deb file to setup the CUDA network repo which will contain the CUDA 10.0 packages that you need.
http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64/cuda-repo-ubuntu1804_10.0.130-1_amd64.deb
              
That was it. Thankyou!
On a QA note, shoudnt that instruction have been in the DeepStream_Release/README for DeepStreamSDK-Tesla-v3.0.tbz2?
Can an admin change this posting thread type so that i can mark it as solved?

Thanks, this also solved my issue.
