## `NeptuneAIConfig`

```python theme={null}
NeptuneAIConfig(
    run_id: str,
    trial_selector: str | int | ForwardRef('BaseTrialSelector') = None,
    column_stack: bool = False,
    group_by: bool = True,
)
```

Method generated by attrs for class NeptuneAIConfig.

### Instance variables

* `model: str`: The model name, which is the run ID of the Neptune run.

* `column_stack: bool`: Compute `vbt.PF.column_stack` to combine portfolio when several  trial numbers are passed. See `tools.tuners.composers`. Default to `False`.

* `group_by: bool`: Group strategy when `column_stack` is `True`. If `False`, compute  individual backtests. Combined all strategy into a single run  otherwise. Defaults to `True`.
