So it seems to be the case that test_operator.py is indeed also run with
GPUs. See (all GPU tests failed for this reason):

rebased. let me know if there are any remaining concerns or if we can merge
this.

Finally got around updating this. I reverted the logic to what I had
originally (as requested) and added a CPU test.

so any test in the `unittest` directory is run with a version of MXNet that
is not compiled with CUDA, is that correct?

that is correct. I'm not sure why it happens or how it can be fixed. With
the recent changes that is what will happen now that it will raise an

so for CPU tests we run MXNet without CUDA built in, meaning that we compile
once for CPU tests and then also for GPU tests with different flags?

I changed the code now to raise an exception when MXNet is built without
CUDA support as per suggestion by @piiswrong.
For the CPU tests I'm

I added a test to `test_operator_gpu.py`.
For CPU only hosts I'm not sure what to test, as a CUDA internal error isn't
exactly the expected

Tried to address all comments. I did not add a test, as CUDA seems to run
into an issue on a CPU only machine, namely raising the following:

@KellenSunderland I also wasn't entirely sure whether this deserves a place
in the core API, but also wasn't sure where else to put it. What would

yeah, I think that makes sense. I will add that test.
