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 2.0, is built with the following options enabled:

• 1-bit SGD
• Async SGD
• Python 3 API
• OpenCV
• Kaldi

The container also includes the following:

• Ubuntu 16.04
• NVIDIA CUDA^® 8.0.61.2 including CUDA^® Basic Linear Algebra Subroutines library™ (cuBLAS) Patch 2
