`


Update '\*var' by subtracting 'alpha' \* 'delta' from it.

## Summary


Args:

- scope: A [Scope](https://www.tensorflow.org/versions/r2.5/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object
- var: Should be from a Variable().
- alpha: Scaling factor. Must be a scalar.
- delta: The change.

<br />


Optional attributes (see
`
https://www.tensorflow.org/versions/r2.5/api_docs/cc/struct/tensorflow/ops/resource-apply-gradient-descent/attrs#structtensorflow_1_1ops_1_1_resource_apply_gradient_descent_1_1_attrs
`
):

- use_locking: If `
  True
  ` , the subtraction will be protected by a lock; otherwise the behavior is undefined, but may exhibit less contention.

Returns:

- the created `
