Comment(by jason):
It looks like it didn't automatically convert from RR to float, like it
should. That's what these two lines should do in sage/rings/real_mpfr.pyx
{{{
cdef object numpy_double_interface = {'typestr': '=f8'}
cdef object numpy_object_interface = {'typestr': '|O'}
}}}
and this property in that same file:
{{{
property __array_interface__:
def __get__(self):
"""
Used for NumPy conversion.
EXAMPLES::
sage: import numpy
sage: numpy.arange(10.0)
array([ 0., 1., 2., 3., 4., 5., 6., 7., 8., 9.])
sage: numpy.array([1.0, 1.1, 1.2]).dtype
dtype('float64')
sage:
numpy.array([1.000000000000000000000000000000000000]).dtype
dtype('object')
"""
if (<RealField_class>self._parent).__prec <= 57: # max size of
repr(float)
return numpy_double_interface
else:
return numpy_object_interface
}}}
So maybe numpy doesn't do something with `__array_interface__` anymore in
linspace?
Can you try `numpy.linspace(0.0,9.0,float(10))`,
`numpy.linspace(0.0,float(9),10)`, `numpy.linspace(float(0),9.0,10)` and
various other combinations of float vs. Sage types in the arguments to
narrow down what is triggering it?
