# nemo_gym.exporters

Run-metadata exporters.

`setup_exporters` opens one exporter per configured backend during global config resolution; call
sites then fan out through the module-level `export_*` helpers.

A backend's module — and with it a multi-hundred-millisecond tracking SDK import — is loaded only
once its config says it is wired up. That is why the registry pairs each backend with a config
model from `config_types` rather than asking the exporter class whether it is available.

### API

```python
nemo_gym.exporters._load_exporter_class(
    class_path: str
) -> type[nemo_gym.exporters.base.BaseExporter]
```

```python
nemo_gym.exporters.export_metrics(
    metrics: dict[str, typing.Any],
    step: typing.Optional[int] = None
) -> None
```

```python
nemo_gym.exporters.export_rollouts(
    rollouts: list[dict[str, typing.Any]]
) -> None
```

```python
nemo_gym.exporters.exporter_extras(
    config: typing.Any
) -> tuple[str, ...]
```

The install extras of every exporter `config` fully configures, in registry order.

A driver that installs Gym must install these too, or the exporter is skipped at run time.

```python
nemo_gym.exporters.get_exporters() -> list[nemo_gym.exporters.base.BaseExporter]
```

The exporters opened for this process. Empty when no backend is configured.

```python
nemo_gym.exporters.setup_exporters(
    global_config_dict: omegaconf.DictConfig
) -> list[nemo_gym.exporters.base.BaseExporter]
```

Open every backend that is fully configured, and log the run config to each.

Replaces any previously opened exporters. A backend that fails to start is skipped with a
warning: telemetry must not take the run down with it.

```python
nemo_gym.exporters.teardown_exporters() -> None
```

Close all open exporters. Safe to call repeatedly and when none are open.

```python
nemo_gym.exporters.EXPORTER_REGISTRY: dict[str, tuple[type[ExporterConfig], str, str]] = {'wandb': (WANDBConfig, 'nemo_gym.exporters.wandb:WandbExporter', 'wandb'), 'mlf...
```

```python
nemo_gym.exporters._EXPORTERS: list[BaseExporter] = []
```

```python
nemo_gym.exporters.logger = logging.getLogger(__name__)
```
