Unable to set the backend to opencl #230
Description
I use the following driver for my card with mesa-opencl-icd loader and radeon driver.
0d:00.0 Display controller: Advanced Micro Devices, Inc. [AMD/ATI] Sun XT [Radeon HD 8670A/8670M/8690M / R5 M330 / M430 / Radeon 520 Mobile] (rev 83)
Subsystem: Hewlett-Packard Company Sun XT [Radeon HD 8670A/8670M/8690M / R5 M330 / M430 / Radeon 520 Mobile]
Installed Arrayfire and made sure that all the libraries are loaded. Using the ArrayFire.jl, arrayfire loads in Julia perfectly and runs on my AMD card.
ArrayFire v3.7.1 (OpenCL, 64-bit Linux, build d9d9b65)
[0] Clover: AMD HAINAN (DRM 2.50.0, 5.4.0-33-generic, LLVM 9.0.1), 2048 MB
But, in my Python the array fire loads with the following info:
ArrayFire v3.7.1 (CPU, 64-bit Linux, build d9d9b65)
[0] Intel: Intel(R) Core(TM) i3-5010U CPU @ 2.10GHz
I also use the following in my .bashrc to update my environment:
export LD_LIBRARY_PATH=/opt/arrayfire/lib64:$LD_LIBRARY_PATH
When I try to change the backend, I get the following error:
>>> af.set_backend('opencl')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/saipavanchitta/.local/lib/python3.8/site-packages/arrayfire/library.py", line 658, in set_backend
raise RuntimeError("Can not change backend to %s after loading %s" % (name, backend.name()))
RuntimeError: Can not change backend to opencl after loading cpu
Is there something that I am missing?

I believe the set_backend call should be the first arrayfire call in C++. I would think that is same here in python wrapper too assuming python wrapper doesn't add anything custom. Try moving set_backend as the first one after importing the package.

I tried calling the set_backend immediately after importing the package.
I still get the same error.

@syurkevi Might have a better idea of what's happening. He should be online soon. Please wait for his response.
