Hello,
I have a test script:
import numpy as np
class MyArray(np.ndarray):
__array_priority__ = 20
def __new__(cls):
return np.asarray(1).view(cls).copy()
def __repr__(self):
return 'my_array'
__str__ = __repr__
def __mul__(self, other):
return super(MyArray, self).__mul__(other)
def __rmul__(self, other):
return super(MyArray, self).__rmul__(other)
mine = MyArray()
print type(np.array(mine,dtype='f'))
The type returned by np.array is ndarray, unless I specifically set
subok=True, in which case I get a MyArray. The default value of subok is
True, so I dont understand why I have to specify subok unless I want it to
be False. Is my subclass missing something important?
Thanks,
Darren
