+title: LightGBM
+---
+
+The [lightgbm_example](https://github.com/allegroai/clearml/blob/master/examples/frameworks/lightgbm/lightgbm_example.py) 
+script demonstrates the integration of ClearML into code that uses LightGBM. 
+
+The example script does the following: 
+* Creates a dataset for LightGBM to train a model
+* Specifies configuration which are automatically captured by ClearML
+* Saves model which ClearML automatically captures
+* Creates an experiment named `LightGBM`, which is associated with the `examples` project.
+
+## Scalars
+
+The scalars logged in the experiment can be visualized in a plot, which appears in the ClearML web UI, in the **experiment's page > RESULTS > SCALARS**.

+
+## Hyperparameters
+
+ClearML automatically logs the configurations applied to LightGBM. They appear in **CONFIGURATIONS > HYPER PARAMETERS > GENERAL**.

+
+## Artifacts
+
+Model artifacts associated with the experiment appear in the info panel of the **EXPERIMENTS** tab and in the info panel of the **MODELS** tab.
