Setup CNTK on your machine
Microsoft Cognitive Toolkit (CNTK) is supported for both Windows and Linux (Ubuntu 16.04). You can do a simple pip install using the commands in this section that assumes Anaconda 3 Python 3.5 environment. Please go to the next section for more installation options.
Once installed you can return to the Getting Started section.
For either Windows or Ubuntu 16.04, we assume you have configured Anaconda Python 3.5 as your active Python environment. If you meet this requirement simply run the following commands from your Python root environment to install CNTK CPU-only version.
On Windows:
pip install https://cntk.ai/PythonWheel/CPU-Only/cntk-2.0rc2-cp35-cp35m-win_amd64.whl
On Ubuntu 16.04:
sudo apt-get install openmpi-bin
pip install https://cntk.ai/PythonWheel/CPU-Only/cntk-2.0rc2-cp35-cp35m-linux_x86_64.whl
You can easily fine tune your PIP installation, further change your environment configuration, tutorial installation, examples, code samples and Jupyter notebooks. For Windows, check out this page, for Linux this one.
For the complete lists of CNTK installation options, see the table below.
The Microsoft Cognitive Toolkit (CNTK) supports both 64-bit Windows and 64-bit Linux platforms. Upon completing the installation, you can return to the Getting Started section.
You can install the complete source code of CNTK and build the binaries on your machine, but we also provide regular binary drops of the CNTK executables, including sample data and sample models.
