I am pretty sure that this is less of a bug, and more of me just not understanding how to use this software. I am on arch linux, I self...

Running the `sqaodpy/example/dense_graph_annealer.py` script without cuda returns ``` h= [4. 4. 4. 4. 4. 4. 4. 4.] J= [[-0. 0.25 0.25 0.25 0.25 0.25 0.25 0.25] [ 0.25 -0. 0.25...
