Today I came across the following cryptic error message when trying to use arrayfire-python: ``` python In [1]: import arrayfire In [2]: arrayfire.backend.name() Out[2]: 'cuda' In [5]: arrayfire.Array() --------------------------------------------------------------------------- RuntimeError...

Add optional parameters to install arrayfire libraries and / or print error messages if arrayfire libs are not found.

This can either be implemented in the wrapper or handled upstream or ideally a combination of both. This should help the integration with other python modules.

Many python modules default to C contiguous layouts. Adding support for this would be nice. This can be solved independently of upstream. Most functions are independent of the layout. The...

Currently, the interpolation function performs the interpolation along the 0th and the 1st axis. However, in my problem of interest, I need to interpolate along all the 4 axes. Could...

Convergence checks performed on the ArrayFire routines for interpolation seem to indicate a few mistakes: The following plot is generated using `af.INTERP.CUBIC` ![download 9](https://cloud.githubusercontent.com/assets/19583419/24001222/90a839b2-0a83-11e7-8d61-dac9f4fd45a3.png) The order of convergence comes out...
