Error due to CUDA settings #115

Closed saioruganti closed 4 years ago

saioruganti commented 5 years ago

I am using KINC:cscm-work branch and ACE:develop branch

I got the following error when I tried to run kinc on local machine and tried to import the expression matrix: Unknown exception caught!\n

Then I realized the issue was due to missing NVIDIA drivers. So I installed the drivers and the issue was resolved while importing the expression matrix.

But the same error occurred when I tried to run the similarity analytic.
The error doesn't occur once I change kinc settings kinc settings set cuda none

I am not sure of what might be the issue or how to resolve it.

@saioruganti I think we need a bit more information on what you did to set up your machine to run KINC. I'm not able to reproduce this problem. I think the fix in ACE that @4ctrl-alt-del applied to automatically disable CUDA will help in this case.

@saioruganti Unfortunately because KINC is built with the CUDA Driver APi, weird things can happen if you don't have the NVIDIA drivers installed, regardless of whether you have a GPU or not.

The above solution is fine, you can just disable CUDA. Another solution is here:

https://github.com/SystemsGenetics/KINC/blob/master/docker/Dockerfile#L21

You can install the NVIDIA "headless driver" which provides just the header files. We use this for our KINC CPU containers and it works perfectly.

I will add this to the troubleshooting docs for future reference.
