I was setting up python and theano for use with gpu on; ubuntu 14.04, GeForce GTX 1080 already installed NVIDIA driver (367.27) and CUDA toolkit (7.5) successfully for the system, but on testing with theano gpu implementation I get the above error (for example; when importing theano with gpu enabled) I have tried to look for possible solutions but didn't succeed. I'm a little new to ubuntu and gpu programming, so I would appreciate any insight into how I can solve this problem. Thanks

2You would need to switch to CUDA 8.0RC which supports that particular compile option, or else change the theano configuration to not compile for your GTX 1080 GPU type. – Robert Crovella Jun 30 '16 at 14:02

2Could you elaborate more on the second option? – absolutelyNoWarranty Aug 06 '16 at 03:51

As Robert Crovella said, SM 6.1 (sm_61) is only supported in CUDA 8.0 and above, and thus you should download CUDA 8.0 Release Candidate from https://developer.nvidia.com/cuda-toolkit
Ubuntu 14.04 is supported, and the instructions on the website on how to setup should be straightforward (copy and paste lines to the console).
I would also recommend downloading CUDA 8.0 when it comes out, since the RC is not the final version.

I was able to find a solution to this problem (since I still want to use CUDA 7.5) by including the following line in the .theanorc file
flags = -arch=sm_52
no more nvcc fatal error
