Hi all,
I'm wondering if the following difference in behavior of object arrays should
be considered a bug. Let a and b be:
In [21]: a = [0,1]
In [22]: b = [ None, None]
If we concatenate a with an empty list, it works:
In [23]: numpy.concatenate(([],a))
Out[23]: array([0, 1])
But not so for b:
In [24]: numpy.concatenate(([],b))

exceptions.ValueError Traceback (most recent
call last)
/home/fperez/<ipython console>
ValueError: 0-d arrays can't be concatenated
I think it's propably a bug:
>>> concatenate((array([]),b))
array([None, None], dtype=object)
