I could have sworn that this use to work: import numpy as np a = np.random.random((100,)) b = (a > 0.5) print a[b, np.newaxis]
But instead, I get this error on the latest master: Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: long() argument must be a string or a number, not 'NoneType' Note, the simple work-around would be "a[b][:, np.newaxis]", but I can't imagine why the intuitive syntax would not be valid. Thanks, Ben Root
