Thank you Fred, that was indeed the issue. After correcting CUDA_VISIBLE_DEVICES, I now get this error:
>>> import theano Using gpu device 0: GeForce GTX 1080 (CNMeM is disabled, cuDNN 5110) /nas/longleaf/apps/python/3.5.1/lib/python3.5/site-packages/theano/sandbox/cuda/__init__.py:600: UserWarning: Your cuDNN version is more recent than the one Theano officially supports. If you see any problems, try updating Theano or downgrading cuDNN to version 5. warnings.warn(warn) >>> I have cuDNN 5.1.10, is it saying I have to have 5.0? Do I have to use the bleeding-edge version of Theano for 5.1.10? I'd rather use stable version.
