# Resources for using Chainer with Amazon SageMaker AI
<a name="chainer"></a>

You can use SageMaker AI to train and deploy a model using custom Chainer code. The SageMaker AI Python SDK Chainer estimators and models and the SageMaker AI open-source Chainer container make writing a Chainer script and running it in SageMaker AI easier. The following section provides reference material you can use to learn how to use Chainer with SageMaker AI.

## What do you want to do?
<a name="chainer-intent"></a>

I want to train a custom Chainer model in SageMaker AI.  
For a sample Jupyter notebook, see the [Chainer example notebooks](https://github.com/awslabs/amazon-sagemaker-examples/tree/master/sagemaker-python-sdk/mxnet_mnist) in the Amazon SageMaker AI Examples GitHub repository.  
For documentation, see [Train a Model with Chainer](https://sagemaker.readthedocs.io/en/stable/using_chainer.html#train-a-model-with-chainer).

I have a Chainer model that I trained in SageMaker AI, and I want to deploy it to a hosted endpoint.  
For more information, see [Deploy Chainer models](https://sagemaker.readthedocs.io/en/stable/using_chainer.html#deploy-chainer-models).

I have a Chainer model that I trained outside of SageMaker AI, and I want to deploy it to a SageMaker AI endpoint  
For more information, see [Deploy Endpoints from Model Data](https://sagemaker.readthedocs.io/en/stable/using_chainer.html#deploy-endpoints-from-model-data).

I want to see the API documentation for [Amazon SageMaker Python SDK](https://sagemaker.readthedocs.io/en/stable) Chainer classes.  
For more information, see [Chainer Classes](https://sagemaker.readthedocs.io/en/stable/sagemaker.chainer.html).

I want to find information about SageMaker AI Chainer containers.  
For more information, see the [SageMaker AI Chainer Container GitHub repository](https://github.com/aws/sagemaker-chainer-container).

 For information about supported Chainer versions, and for general information about writing Chainer training scripts and using Chainer estimators and models with SageMaker AI, see [Using Chainer with the SageMaker Python SDK](https://sagemaker.readthedocs.io/en/stable/using_chainer.html).
