I've been attempting to use theano for pthon on my GPU (a 980m) with GCC 6.2.0 and G++ 6.2.0 for Python 3.5.1 on Ubuntu 16.04. I've installed all prerequisites as per the instructions and Theano given no errors on import. However, when I run theano.test() I get the following rather verbose ad cryptic error.
===============================
nvcc warning : The 'compute_20', 'sm_20', and 'sm_21' architectures are deprecated, and may be removed in a future release (Use -Wno-deprecated-gpu-targets to suppress warning).

Given the syntax-like errors, I'm guessing it's a compiler issue of some sort, or perhaps Theano not knowing where to find my GCC or G++, but rather than mucking about aimlessly, I was wondering if anyone could shed some light on this.
