Error when launching driveworks samples

Autonomous Vehicles DRIVE PX 2 DriveWorks
1

I tried to launch sample_drivenet in my host PC when i had installed Driveworks SDK, but it showed this error:
./sample_drivenet: error while loading shared libraries: libcuda.so.1: cannot open shared object file: No such file or directory

I found libcuda.so.1 and add it’s address to the LD_LIBRARY_PATH like this:
export LD_LIBRARY_PATH=/home/nvidia/nvidia_sdk/DRIVE/Linux/5.0.10.3/OS/DriveSDK/drive-t186ref-linux/lib-target:$LD_LIBRARY_PATH

but the error still remained, what can i do now?

Additionally,can i use driveworks SDK in VMware in my host PC?

Waiting for your answers.Thanks

hi,

try sudo ldconfig /usr/local/your/cuda/path.

I guess, you cannot run samples on VM. Atleast for me it didnt work. But I never tried on VMware. You need all the CUDA stuff installed on VMware to make sure it works.

hi,

Thanks for your answer.

I tried your methods but it didn’t work. So sad.

And i tried to use google to find answers, some people said it’s wrong with my NVIDIA drive, so i changed my NVIDIA drive using NVIDIA-Linux-x86_64-396.18.run, and the error changed to:

And when i changed the driver to NVIDIA 396.26, the error became:

now i still don’t know how to solve it…

which CUDA version you have? Please make sure you are using CUDA 9 and libCUDNN for particular CUDA version.

5

I agree. It is working.

6

My CUDA version is 9.2.88. And CUDNN is 7103(define CUDNN_MAJOR 7 define CUDNN_MINOR 1 define CUDNN_PATCHLEVEL 3)

Should i change to CUDA 9.0?

Hi,

You can remove cuda and driveworks. Reinstall Driveworks, and it automatically install CUDA for you. For me DW0.6 works fine and you can DriveInstall 5.0.5.0b Linux version from the archive.

Thanks. I’ll try it.
