Each element in the list should be the response for the corresponding element in the request array. Each element must contain a response (a response can be either output tensors or an error); an element cannot be None.Triton checks to ensure that these requirements on response list are satis...
def all(iterable): for element in iterable: if not element: return False return True all([]) returns True since the iterable is empty. all([[]]) returns False because the passed array has one element, [], and in python, an empty list is falsy. all([[[]]]) and higher recursive ...
