[Numpy-discussion] numpy.fromfunction() doesn't work as expected?

July 19, 2012

      Hi All,

I have spot a strange behavior of numpy.fromfunction(). The sample codes are
as follows:
...
...
...
import numpy as np
...
...
...
def myOnes(i,j):
return 1.0
...
...
...
a = np.fromfunction(myOnes,(2000,2000))
...
...
...
a
1.0

Actually what I expected is that the function will return a 2000*2000 2d
array with unit value. The returned single float value really confused me.
Is this a known bug? The numpy version I used is 1.6.1.

Regards,

Cheng
