I actually figured it out. I went one level down in the array and it took it. -----Original Message----- From: numpy-discussion-bounces@scipy.org [mailto:numpy-discussion-bounces@scipy.org] On Behalf Of Chris.Barker Sent: Friday, December 09, 2011 3:33 PM To: Discussion of Numerical Python Subject: EXTERNAL: Re: [Numpy-discussion] Problem with using PyArray_AsCArray On 12/9/11 11:25 AM, Ng, Enrico wrote:

I understand that SWIG, Boost, et. al are perhaps too heavyweight for this one use, but you might want to give Cython a try. It makes it really easy to grab a numpy array (and tst it for compliance), and then you can do whatever you want with the data pointer: http://wiki.cython.org/tutorials/numpy http://wiki.cython.org/WrappingNumpy (this one is marked as depricated, but may be what you want in your case, as you do want a raw C array) Some wore googling and browsing of the Cython list will likely yield examples similar to yours. -Chris -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception Chris.Barker@noaa.gov _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
