I reproduced the issue with Pierre's script also in numpy 1.6.1 and
latest github (2.0.0.dev-b8bfcd0). In newer versions the error message
is:
Traceback (most recent call last):
File "ma_tiling_issue.py", line 18, in <module>
a/100. #raises ValueError: invalid return array shape
File "/usr/local/lib/python2.7/dist-packages/numpy/ma/core.py", line
3654, in __div__
return divide(self, other)
File "/usr/local/lib/python2.7/dist-packages/numpy/ma/core.py", line
1078, in __call__
m |= ma
ValueError: non-broadcastable output operand with shape (3,3,3)
doesn't match the broadcast shape (1,3,3,3)
I still don't know what's going on. Is the internal representation
(shape) of the array changed by the tile instruction?
I created a ticket: http://projects.scipy.org/numpy/ticket/2035
