How would I copy data from an ArrayFire array to a regular Python array on the host CPU in wrapper?

[Cole Shores]

How would I copy array data from an ArrayFire array to a regular python array on the host CPU using the Python wrapper?

I know I could use a host pointer to the data using C/C++ but Im not sure how that is accomplished using this wrapper.

How would I copy my array data to and from ArrayFire?

Thanks in advance,

Cole

On C++, this works like this:

array a = <array data here>

float ahost[] = a.host()

There may be something similar in Python that implements this functionality.

Hi Cole,

Anubhab is right. The proper function for this is to call a.to_array(). You can get a python list by using a.to_list().

You can look at other methods by starting python (or ipython) REPL and running help(af.Array)

If you'd prefer, you can use our chatroom for some quick responses: https://gitter.im/arrayfire/arrayfire-python
