sagemaker 1.50.13

Open source library for training and deploying models on Amazon SageMaker.

SageMaker Python SDK

SageMaker Python SDK is an open source library for training and deploying machine learning models on Amazon SageMaker.

With the SDK, you can train and deploy models using popular deep learning frameworks Apache MXNet and TensorFlow. You can also train and deploy models with Amazon algorithms, which are scalable implementations of core machine learning algorithms that are optimized for SageMaker and GPU training. If you have your own algorithms built into SageMaker compatible Docker containers, you can train and host models using these as well.

Installing the SageMaker Python SDK

The SageMaker Python SDK is built to PyPI and can be installed with pip as follows:

pip install sagemaker

You can install from source by cloning this repository and running a pip install command in the root directory of the repository:

git clone https://github.com/aws/sagemaker-python-sdk.git
cd sagemaker-python-sdk
pip install .

Supported Operating Systems

SageMaker Python SDK supports Unix/Linux and Mac.

Supported Python Versions

SageMaker Python SDK is tested on:

• Python 2.7

• Python 3.6

AWS Permissions

As a managed service, Amazon SageMaker performs operations on your behalf on the AWS hardware that is managed by Amazon SageMaker. Amazon SageMaker can perform only operations that the user permits. You can read more about which permissions are necessary in the AWS Documentation.

The SageMaker Python SDK should not require any additional permissions aside from what is required for using SageMaker. However, if you are using an IAM role with a path in it, you should grant permission for iam:GetRole.

Licensing

SageMaker Python SDK is licensed under the Apache 2.0 License. It is copyright 2018 Amazon.com, Inc. or its affiliates. All Rights Reserved. The license is available at: http://aws.amazon.com/apache2.0/

Running tests

SageMaker Python SDK has unit tests and integration tests.

You can install the libraries needed to run the tests by running pip install --upgrade .[test] or, for Zsh users: pip install --upgrade .\[test\]

Unit tests

We run unit tests with tox, which is a program that lets you run unit tests for multiple Python versions, and also make sure the code fits our style guidelines. We run tox with Python 2.7 and 3.6, so to run unit tests with the same configuration we do, you’ll need to have interpreters for Python 2.7 and Python 3.6 installed.

To run the unit tests with tox, run:

tox tests/unit

Integrations tests

To run the integration tests, the following prerequisites must be met

1. AWS account credentials are available in the environment for the boto3 client to use.

2. The AWS account has an IAM role named SageMakerRole. It should have the AmazonSageMakerFullAccess policy attached as well as a policy with the necessary permissions to use Elastic Inference.

We recommend selectively running just those integration tests you’d like to run. You can filter by individual test function names with:

tox -- -k 'test_i_care_about'

You can also run all of the integration tests by running the following command, which runs them in sequence, which may take a while:

tox -- tests/integ

You can also run them in parallel:

tox -- -n auto tests/integ

Supported major version of Spark: 2.2 (MLeap version - 0.9.6)

Here is an example on how to create an instance of SparkMLModel class and use deploy() method to create an endpoint which can be used to perform prediction against your trained SparkML Model.

sparkml_model = SparkMLModel(model_data='s3://path/to/model.tar.gz', env={'SAGEMAKER_SPARKML_SCHEMA': schema})
model_name = 'sparkml-model'
endpoint_name = 'sparkml-endpoint'
predictor = sparkml_model.deploy(initial_instance_count=1, instance_type='ml.c4.xlarge', endpoint_name=endpoint_name)

Once the model is deployed, we can invoke the endpoint with a CSV payload like this:

payload = 'field_1,field_2,field_3,field_4,field_5'
predictor.predict(payload)

For more information about the different content-type and Accept formats as well as the structure of the schema that SageMaker SparkML Serving recognizes, please see SageMaker SparkML Serving Container.
