Research direction

Start at library.py line 646, where backend loading iterates over the listed backends, and inspect the import path triggered by import arrayfire as af. Verify that backend loading follows the documented preference order and that importing ArrayFire no longer returns early without loading a backend.

Written by the indexing model from the issue text.

Description

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 a set, which doesn't keep the order. In my Linux computer, when I run import arrayfire as af, the function will be called and it loads "" first, and due to err!=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.
