Array type issue at import when using PyPy

Here is the traceback:

I'm using the Windows binary release of Pypy and installed numpy using: 'pip install git+https://bitbucket.org/pypy/numpy.git'. PyDAQmx was installed using 'pip install PyDAQmx' (v 1.3.1).

Your error comes from the following command, which works well on C Python.

numpy.ctypeslib.ndpointer(numpy.int32, flags=('C_CONTIGUOUS', 'WRITEABLE'))

It seams to me that it is an error from the PyPy fork of numpy and not
from PyDAmx. You should try to ask them.

This particular issue should be solved in numpypy now, cf. https://bitbucket.org/pypy/numpy/commits/6b5083ac1859da3fab0e6229f8367ad544239896. However, I have no idea whether it's enough to get PyDAQmx working.

@clade, thank you for your answer. You are right, this is on PyPy numpy side rather than in PyDAQmx. Feel free to close this issue!
