NumPy Array to AF Array in Windows + python2.7

[ghost]

data=np.random.random(size=(100,100)) af.np_to_af_array(data)

gets error: af.np_to_af_array(data) File "C:\Python27\lib\site-packages\arrayfire\interop.py", line 53, in np_to_af_array res = Array(in_ptr, shape, in_dtype) File "C:\Python27\lib\site-packages\arrayfire\array.py", line 428, in init raise TypeError("src is an object of unsupported class") TypeError: src is an object of unsupported class

My Environment: Python27 64 bit Windows 7 64 AF version: 3.3.2 or sys.version_info(major=2, minor=7, micro=10, releaselevel='final', serial=0) CUDA kit 7.5

More background: I just installed the package so likely a setup issue on my side... The examples work for me, both cpu & cuda.

Any ideas?

@bscully Can you tell me how you installed arrayfire python wrapper?

[ghost]

pip install arrayfire

Should I try another way?

@bscully can you print out the output of isinstance(data.ctypes.data, int)

[ghost]

isinstance(data.ctypes.data, int) Out[58]: False

@bscully output of type(data.ctypes.data) please.

Can you also let me know if you are using a different python distribution ?

[pavanky]

@ZacDiggum I assume you are also on windows but are not seeing this issue?

[ghost]

type(data.ctypes.data) Out[61]: long

I'm running everything on windows and it's the standalone version, ie not anaconda or enthought etc

Update: The calculation examples work but not the graphics.

more info: I do have a 2nd distribution with Anaconda. Switching between the 2 is easy which is why I said the standard python earlier. I started using PyCuda and could only get that to work with Anaconda.

Might be related to this error..

[pavanky]

looks like the original error only happens on windows + python 2.7. I will try to patch this in and make a release today.

[pavanky]

Fixed in master and latest release.

[pavanky]

@bscully This does not fix the graphics issues. If you are still having those errors, please create a new issue for it.

[ghost]

Uninstalled, ran pip install and now it works!! Interestingly when i tried compiling the master branch which looks to be version 3.4, it did not work. Does that make sense?

Either way, the current pip install is working great - thanks so much!

And as for the graphics error, will log another case.

[pavanky]

@bscully If you are using the command from the README (or use git clone), it uses develop branch not master. I patched this only in master so far. I will merge it into devel soon.

[pavanky]

@bscully FYI, I just merged the fixes into devel branch as well.
