Microsoft Cognitive Toolkit Release 16.12 (PDF)

The NVIDIA container image of Microsoft Cognitive Toolkit, release 16.12, is available.

Microsoft Cognitive Toolkit container image version 16.12 is based on Microsoft Cognitive Toolkit 2.0.beta5.0.

Contents of the Microsoft Cognitive Toolkit

This container image contains the source files that are used to build the Microsoft Cognitive Toolkit in the /opt/cntk directory. The Microsoft Cognitive Toolkit binaries are pre-built and installed into the /usr/local/cntk directory.

A Python 3.4 Conda environment (including the Microsoft Cognitive Toolkit module) is installed in the /opt/conda/envs/cntk-py34 directory. This is included in PATH, so by default the python command executes a Python 3.4 interpreter. To use the base Ubuntu Python 2.7 binary, you can either adjust PATH or explicitly call /usr/bin/python. This image of the Microsoft Cognitive Toolkit, 2.0beta5.0, is built with the following options enabled:

  • 1-bit SGD
  • Async SGD
  • Python API
  • OpenCV
  • Kaldi

The container also includes the following:
