The AWS Deep Learning AMIs for Ubuntu and Amazon Linux now come with newer versions of MXNet 1.3 and CNTK 2.6 . MXNet 1.3 provides improved support for Intel’s Math Kernel Library for Deep Neural Networks (Intel MKL-DNN), new pre-trained computer vision models in the Gluon Model Zoo library, and support for Clojure programming language. CNTK 2.6 provides improved support for Open Neural Network Exchange (ONNX), which is an open data format that allows you to design, train, and deploy deep learning models with any framework you choose. Deep Learning AMIs automatically deploy the framework builds optimized for the EC2 instance you select when you activate the framework’s virtual environment for the first time.
