## Public functions

### UseLocking

```
TF_MUST_USE_RESULT Attrs tensorflow::ops::ResourceApplyMomentum::Attrs::UseLocking(
  bool x
)
```
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.

Defaults to false

### UseNesterov

```
TF_MUST_USE_RESULT Attrs tensorflow::ops::ResourceApplyMomentum::Attrs::UseNesterov(
  bool x
)
```
If `True`, the tensor passed to compute grad will be var - lr \* momentum \* accum, so in the end, the var you get is actually var - lr \* momentum \* accum.

Defaults to false
