nvcc fatal : Value 'sm_61' is not defined for option 'gpu-architecture' error with theano
Question: I was setting up python and theano for use with gpu on; ubunutu 14.04, GeForce
GTX 1080 already installed NVIDIA driver (367.27) and CUDA toolkits (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 and gpu programming, so I would appreciate any insight into how
I can solve this problem. Thanks


Answer: 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.
