This line has a comment# Iterate in reverse order of preference. However, it loads them with some random order, because the object to iterate is aset, which doesn't keep the order. In my Linux computer, when I runimport arrayfire as af, the function will be called and it loads"" first, and due toerr!=0, it directly returns and not loads anything.

By the way, I simply change{"cpu", "opencl", "cuda", ""} to["cuda"] and I can import arrayfire with no error.
