Today Apache MXNet community announced the 1.2 release of the Apache MXNet deep learning framework. The new capabilities in MXNet provide the following benefits to users:

  1. MXNet is easier to use
  • New scala inference APIs: This release includes new Scala inference APIs which offer an easy-to-use, Scala idiomatic and thread-safe high level APIs for performing predictions with deep learning models trained with MXNet.
  • Exception Handling Support for Operators: MXNet now transports backend C++ exceptions to the different language front-ends and prevents crashes when exceptions are thrown during operator execution

MXNet is faster
  • MKL-DNN integration: MXNet now integrates with Intel MKL-DNN to accelerate neural network operators: Convolution, Deconvolution, FullyConnected, Pooling, Batch Normalization, Activation, LRN, Softmax, as well as some common operators: sum and concat. This integration allows NDArray to contain data with MKL-DNN layouts and reduces data layout conversion to get the maximal performance from MKL-DNN. Currently, the MKL-DNN integration is still experimental.
  • Enhanced FP16 support: MXNet now adds support for distributed mixed precision training with FP16. It supports storing of master copy of weights in float32 with the multi_precision mode of optimizers. Improved speed of float16 operations on x86 CPU by 8 times through F16C instruction set.

MXNet provides easy interoperability
  • Import ONNX models into MXNet: Implemented a new ONNX module in MXNet which offers an easy to use API to import ONNX models into MXNet's symbolic interface. Checkout the example on how you could use this API to import ONNX models and perform inference on MXNet. Currently, the ONNX-MXNet Import module is still experimental.

Getting started with MXNet


Getting started with MXNet is simple.
