+title: MegEngine MNIST
+---
+
+The [megengine_mnist.py](https://github.com/allegroai/clearml/blob/master/examples/frameworks/megengine/megengine_mnist.py) 
+example demonstrates the integration of ClearML into code that uses [MegEngine](https://github.com/MegEngine/MegEngine) 
+and [TensorBoardX](https://github.com/lanpa/tensorboardX). ClearML automatically captures models saved with `megengine`.
+
+The example script does the following:
+* Trains a simple deep neural network on MegEngine's built-in [MNIST](https://megengine.org.cn/doc/stable/en/reference/api/megengine.data.dataset.MNIST.html)
+  dataset.
+* Creates a TensorBoardX `SummaryWriter` object to log scalars during training.  
+* Creates a ClearML experiment named `megengine mnist train`, which is associated with the `examples` project.
+
+## Hyperparameters
+
+ClearML automatically logs command line options defined with `argparse`. They appear in the experiment's **CONFIGURATIONS** 
+page under **HYPER PARAMETERS** **>** **Args**.
+
+![Configuration tab](../../../img/examples_megengine_mnist_config.png)
+
+## Scalars
+
+The example script's `train` function calls TensorBoardX's `SummaryWriter.add_scalar` method to report `loss`. 
+ClearML automatically captures the data that is added to the `SummaryWriter` object.  
+
+These scalars can be visualized in plots, which appear in the ClearML [WebApp](../../../webapp/webapp_home.md), in the 
+experiment's **RESULTS** **>** **SCALARS** page.
+
+
+![Scalars tab](../../../img/examples_megengine_mnist_scalars.png)
+
+## Models
+
+ClearML automatically captures the model logged using the `megengine.save` method, and saves it as an artifact.
+
+View saved snapshots in the experiment's **ARTIFACTS** tab.
+
+![Artifacts tab](../../../img/examples_megengine_models_1.png) 
+
+To view the model details, click the model name in the **ARTIFACTS** page, which will open the model's info tab. Alternatively, download the model.
+
+The model info panel contains the model details, including: 
+* Model URL
+* Framework
+* Snapshot locations.
+

+## Console
+
+All console output during the script’s execution appears in the experiment’s **RESULTS > CONSOLE** page.
