<img className="inline m-0" src="https://storage.googleapis.com/arize-phoenix-assets/assets/images/arize-docs-images/9e9834e4-image.jpeg" /> [View Source on Github](https://github.com/Arize-ai/client_python/blob/576b5e62ac11124dd27201bc3db7587c46d9a371/arize/utils/types.py#L38)

Arize enum for metrics grouping when validating a schema column in [`log()`](/api-clients/python/version-7/ml-logging/arize-pandas/log) call.

| Use Case       | SDK Metric               | Metric                                                              |
| -------------- | ------------------------ | ------------------------------------------------------------------- |
| Regression     | `Metrics.REGRESSION`     | MAPE, MAE, RMSE, MSE, R-Squared, Mean Error                         |
| Classification | `Metrics.CLASSIFICATION` | Accuracy, Recall, Precision, FPR, FNR, F1, Sensitivity, Specificity |
| Ranking        | `Metrics.RANKING`        | NDCG                                                                |
| AUC & LogLoss  | `Metrics.AUC_LOG_LOSS`   | AUC, PR-AUC, Log Loss                                               |
| Ranking Label  | `Metrics.RANKING_LABEL`  | GroupAUC, MAP, MRR                                                  |

### Method

`repr()`

To view applicable metrics, pass in your desired **SDK Metric** from above.

```python theme={null}
repr(Metrics.[SDK Metric])
```

### Code Example

```javascript theme={null}
response = arize_client.log(
  (model_id = "sample-binary-classification-model"),
  ...(metrics_validation = [Metrics.CLASSIFICATION])
);

response = arize_client.log(
  (model_id = "sample-regression-model"),
  ...(metrics_validation = [Metrics.REGRESSION])
);

response = arize_client.log(
  (model_id = "sample-ranking-model"),
  ...(metrics_validation = [Metrics.RANKING, Metrics.RANKING_LABEL])
);
```
