| [`get_actor_compute_strategy_for_stage`](#nemo_curator-backends-ray_data-utils-get_actor_compute_strategy_for_stage) | Get the Ray Data actor-pool compute strategy for a processing stage. |
| [`is_actor_stage`](#nemo_curator-backends-ray_data-utils-is_actor_stage)                                             | Check if the stage is an actor stage.                                |

### API

```python
nemo_curator.backends.ray_data.utils.get_actor_compute_strategy_for_stage(
    stage: nemo_curator.stages.base.ProcessingStage
) -> ray.data.ActorPoolStrategy
```

Get the Ray Data actor-pool compute strategy for a processing stage.

Explicit stage `num_workers` requests a fixed-size actor pool. Otherwise,
actor stages use Ray Data's autoscaling pool and can optionally override
min/max/initial workers through `ray_stage_spec`.

```python
nemo_curator.backends.ray_data.utils.is_actor_stage(
    stage: nemo_curator.stages.base.ProcessingStage
) -> bool
```

Check if the stage is an actor stage.
