what is nvidia-cuda-toolkit

Hi there,

I am a beginner, so please don’t laugh at my question.

I installed cuda 9.1 with nvidia driver 390.25 by typing sudo apt-get install cuda

And then I sudo apt-get nvidia-cuda-toolkit.

Will there any conflicts?

Thank you.


read the linux install guide:


cuda and cuda-toolkit are packages provided by the NVIDIA installer packages

nvidia-cuda-toolkit is provided by somebody else (e.g. another package in your packaging system, such as those provided by Ubuntu maintainers)

cuda-toolkit and cuda should not conflict.

Hard to say anything about nvidia-cuda-toolkit - it was created by someone else
