Unable to create a sparse matrix from the host

[elbehery95]

I was trying to follow the documentation in order to create a sparse matrix of type csr

import arrayfire as af

x = af.sparse.create_sparse_from_host([1,2], [1, 2], [1, 2], nrows=int(123), ncols=int(123))

though i am having this error

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "G:\behery_tools\Python36\lib\site-packages\arrayfire\sparse.py", line 93, in create_sparse_from_host

  File "G:\behery_tools\Python36\lib\site-packages\arrayfire\sparse.py", line 60, in create_sparse

In file src\api\c\sparse.cpp:85
Invalid argument at index 4
Expected: rInfo.getType() == s32

I am not sure what is the main cause of the error here; as much as i know i am passing the correct types for all the args. Can anyone provide an example ?

Thank you for reporting this, @ELBe7ery.

Incorrect array types were being passed in to ArrayFire. PR #198 contains fix.
