foldl(
    fn,
    elems,
    initializer=None,
    name=None
)

Defined in tensorflow/contrib/keras/python/keras/backend.py.

Reduce elems using fn to combine them from left to right.

Arguments:

fn: Callable that will be called upon each element in elems and an
    accumulator, for instance `lambda acc, x: acc + x`
elems: tensor
initializer: The first value used (`elems[0]` in case of None)
name: A string name for the foldl node in the graph

Returns:

Tensor with same type and shape as `initializer`.
