I have an object that exposes an array interface. I want to modify the data it contains, but using numpy.array(myObject) seems to copy the data and thus my object is not modified. Am I mistaken or did I make a mistake in my array interface ?
I think numpy.array(object) always makes a copy.
You want numpy.asarray(object) which will make a view if object exposes the array interface and matches the type and sizes requested.
Thank you for the tip, I'll try it this evening. I checked that the data is actually copied, so this should be what I need ;) Matthieu -- French PhD student Website : http://miles.developpez.com/ Blogs : http://matt.eifelle.com and http://blog.developpez.com/?blog=92 LinkedIn : http://www.linkedin.com/in/matthieubrucher
