Hi All, It turns out that gufuncs will broadcast the last dimension if it is one. For instance, inner1d has signature `(n), (n) -> ()`, yet
In [27]: inner1d([1,1,1], [1]) Out[27]: 3 In [28]: inner1d([1,1,1], [1,1]) --------------------------------------------------------------------------- ValueError Traceback (most recent call last) <ipython-input-28-e53e62e35349> in <module>() ----> 1 inner1d([1,1,1], [1,1]) ValueError: inner1d: Operand 1 has a mismatch in its core dimension 0, with gufunc signature (i),(i)->() (size 2 is different from 3) I'd think this is a bug, as the dimensions should match. Note that scalar 1 will be promoted to [1] in this case. Thoughts? Chuck
