Args
var	A Tensor of type resource. Should be from a Variable().
m	A Tensor of type resource. Should be from a Variable().
v	A Tensor of type resource. Should be from a Variable().
beta1_power	A Tensor. Must be one of the following types: float32, float64, int32, uint8, int16, int8, complex64, int64, qint8, quint8, qint32, bfloat16, qint16, quint16, uint16, complex128, half, uint32, uint64. Must be a scalar.
beta2_power	A Tensor. Must have the same type as beta1_power. Must be a scalar.
lr	A Tensor. Must have the same type as beta1_power. Scaling factor. Must be a scalar.
beta1	A Tensor. Must have the same type as beta1_power. Momentum factor. Must be a scalar.
beta2	A Tensor. Must have the same type as beta1_power. Momentum factor. Must be a scalar.
epsilon	A Tensor. Must have the same type as beta1_power. Ridge term. Must be a scalar.
grad	A Tensor. Must have the same type as beta1_power. The gradient.
use_locking	An optional bool. Defaults to False. If True, updating of the var, m, and v tensors will be protected by a lock; otherwise the behavior is undefined, but may exhibit less contention.
use_nesterov	An optional bool. Defaults to False. If True, uses the nesterov update.
name	A name for the operation (optional).

Returns
The created Operation.
