NuGet Package

Overview

The CNTK Eval NuGet package is a NuGet package containing the necessary libraries and assemblies to enable .NET and Windows C++ applications to perform CNTK model evaluation. There are 3 Nuget packages:

• CNTK.CPUOnly: provides CNTK C#/.NET Managed Eval Library and C++ Library for CPU only machines.
• CNTK.GPU: provides CNTK C#/.NET Managed Eval Library and C++ Library for GPU enabled machines.
• Microsoft.Research.CNTK.CpuEval-mkl: provides CNTK EvalDll API. It supports CPU only.

Installation

The package may be obtained through the NuGet Package Manager inside Visual Studio by searching for "CNTK", or downloaded directly from NuGet:

• https://www.nuget.org/packages/CNTK.CPUOnly/2.0.0-rc2
• https://www.nuget.org/packages/CNTK.GPU/2.0.0-rc2
• https://www.nuget.org/packages/Microsoft.Research.CNTK.CpuEval-mkl/2.0.0-rc2

The current version is 2.0-rc2. When installing, please select the option "Include Prerelease" in "Manage Nuget Packages".

The CNTK NuGet packages may be installed on a Visual C++ or .NET project (C#, VB.Net, F#, ...). The Nuget package contains both debug and release versions of C++ library and dlls, and the release version of C# assembly and its dependent dlls. Once installed the project will contain a reference to the managed dll and the required dependent binary libraries will be copied to the output directory after building the project.

For instructions on how to install a NuGet package, please refer to the NuGet documentation at: https://docs.nuget.org/consume/installing-nuget

Current Release

The current release of CNTK Eval Nuget Packages support the following interfaces

• CNTK Library Managed Eval Interface
• CNTK Library C++ Eval Interface
• EvalDll C# Interface
• EvalDll C++ Interface

Linux

There is a Linux equivalent set of libraries (albeit not available through NuGet) that enables CNTK model evaluations in Linux using C++. Refer to the CNTK Evaluation Overview page for details.
