Open Source News from the AWS Summit San Francisco

The AWS Summit in San Francisco on April 4th saw a slew of announcements, including some in open source:

SAM Implementation is now open source!

“In 2016, we launched SAM and opened up the SAM specification on this Github repo to invite collaborators. We’ve loved your questions, proposals for new features, enhancements to examples, bug reports, and passionate discussions around developing serverless applications.

Today, we are incredibly excited to open source the underlying SAM implementation – the Python code that converts SAM templates to CloudFormation stacks. Now, in addition to proposing changes to the SAM Spec, you can contribute new features and enhancements to all of SAM! You’ll find the code under the samtranslator folder and the tests under the tests directory.” – GitHub, AWS What’s New, Slack Channel

Amazon SageMaker Now Supports Additional Instance Types, Local Mode, Open Sourced Containers, MXNet and Tensorflow Updates

“Today Amazon SageMaker has open sourced the MXNet and Tensorflow deep learning containers that power the MXNet and Tensorflow estimators in the SageMaker SDK. … These containers launch with support for Tensorflow 1.6.0 and MXNet 1.1.0 as well. Tensorflow has a number of new 1.6.0 features including support for CUDA 9.0, cuDNN 7, and AVX instructions which allows for significant speedups in many training applications. MXNet 1.1.0 adds a number of new features including a Text API mxnet.text with support for text processing, indexing, glossaries, and more. Two of the really cool pre-trained embeddings included are GloVe and fastText.” – Randall Hunt in the AWS News blog, AWS What’s New
