I thought #6053 fixed the notebook numpy issue. Is there more to the
issue than what is done there? Are the tests above being done on 4.0
(e.g., sagenb.org)?
The following works fine on sage 4.0 (e.g., sagenb.org):
%cython
cimport numpy as np
import numpy as np
DTYPE = np.int
ctypedef np.npy_intp DTYPE_t
Note that I had to change the ctypedef. There is no int_t defined in
the numpy.pxd file (devel/sage/sage/ext/numpy.pxd). Should there be an
np.int_t type?
