Yes. The numpy license is compatible with the GPL license, so code
from numpy may be incorporated into GPL programs.

The clearest thing to do is to keep the _cook_nd_args() function
implemented in its own file which has the numpy license text placed in
a comment at the top. You should have a LICENSE.txt file that says
that your program is GPLed (and point to the COPYING file that
contains the GPL text) and also mentions that the _cook_nd_args file
(which you should mention by name) has the numpy license. Since the
numpy license is relatively small, you can just copy the full numpy
license into your LICENSE.txt file. Something like this:
