<br />

    tf.raw_ops.ResourceApplyKerasMomentum(
        var,
        accum,
        lr,
        grad,
        momentum,
        use_locking=False,
        use_nesterov=False,
        name=None
    )

Set use_nesterov = True if you want to use Nesterov momentum.

accum = accum \* momentum - lr \* grad
var += accum

| ## Args ||
|---|---|
| `var` | A `Tensor` of type `resource`. Should be from a Variable(). |
| `accum` | A `Tensor` of type `resource`. Should be from a Variable(). |
| `lr` | 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`. Scaling factor. Must be a scalar. |
| `grad` | A `Tensor`. Must have the same type as `lr`. The gradient. |
| `momentum` | A `Tensor`. Must have the same type as `lr`. Momentum. Must be a scalar. |
| `use_locking` | An optional `bool`. Defaults to `False`. If `True`, updating of the var and accum 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`, the tensor passed to compute grad will be var + momentum \* accum, so in the end, the var you get is actually var + momentum \* accum. |
| `name` | A name for the operation (optional). |
