+title: CatBoost
+---
+
+The [catboost_example.py](https://github.com/allegroai/clearml/blob/master/examples/frameworks/catboost/catboost_example.py) 
+example demonstrates the integration of ClearML into code that uses [CatBoost](https://catboost.ai).
+
+The example script does the following:
+* Trains a simple deep neural network on the CatBoost built-in [msrank](https://catboost.ai/en/docs/concepts/python-reference_datasets_msrank) 
+  dataset.
+* Creates an experiment named `CatBoost simple example` in the `examples` project
+* ClearML automatically logs argparse command line options, and models and metrics logged by CatBoost
+
+## Scalars
+ClearML automatically captures scalars logged by CatBoost. These scalars can be visualized in plots, which appear in the 
+[ClearML web UI](../../../webapp/webapp_overview.md), in the experiment's page **> RESULTS > SCALARS**.
+
+![Experiment scalars](../../../img/examples_catboost_scalars.png)
+
+## Hyperparameters
+ClearML automatically logs command line options defined with argparse. They appear in **CONFIGURATIONS > HYPER 
+PARAMETERS > Args**.
+
+![Experiment hyperparameters](../../../img/examples_catboost_configurations.png)
+
+## Console
+Text printed to the console for training progress, as well as all other console output, appear in **RESULTS > CONSOLE**.
+
+![Experiment console](../../../img/examples_catboost_console.png)
+
+## Artifacts
+Models created by the experiment appear in the experiment’s **ARTIFACTS** tab. ClearML automatically logs and tracks 
+models created using CatBoost.
+
+![Experiment artifacts](../../../img/examples_catboost_artifacts.png)
+
+Clicking on the model name takes you to the [model’s page](../../../webapp/webapp_model_viewing.md), where you can view 
+the model’s details and access the model.
