#EvalClients

The folder contains some examples using the CNTK to evaluate a trained model in your application. Please note that Visual Studio 2015 update 3 is required, and only the 64-bit target is supported.

The [CNTK Eval Examples](https://docs.microsoft.com/en-us/cognitive-toolkit/CNTK-Eval-Examples) page provides more details of these examples.

# CNTK Library Eval C++/C# Examples

The CNTKLibraryEvalExamples.sln contains code samples demonstrating how to use the CNTK Library API in C++ and C#.

* CNTKLibraryCSEvalCPUOnlyExamples uses the CNTK Library CPU-Only Nuget package to evaluate models on CPU-only devices in C#.
* CNTKLibraryCSEvalGPUExamples uses the CNTK Library GPU Nuget package to evaluate models on GPU devices in C#.
* CNTKLibraryCPPEvalCPUOnlyExamples uses the CNTK Library C++ API to evaluate models on CPU-only devices. It uses the CNTK Library CPU-Only Nuget package.
* CNTKLibraryCPPEvalGPUExamples uses the CNTK Library C++ API to evaluate models on GPU devices. It uses the CNTK Library GPU Nuget package.

After a successful build, the executable is saved under the $(SolutionDir)..\..$(Platform)$(ProjectName).$(Configuration)\ folder, e.g. ..\..\X64\CNTKLibraryCSEvalCPUOnlyExamples.Release\CNTKLibraryCSEvalCPUOnlyExamples.exe.
On Linux, only C++ is supported. Please refer to Makefile for building samples. The target name CNTKLIBRARY_CPP_EVAL_EXAMPLES is used to build CNTKLibraryCPPEvalExamples.

# EvalDll Eval C++/C# Examples

The EvalClients.sln contains the following projects demonstrating how to use the EvalDll library in C++ and C#.

* CPPEvalClient: this sample uses the C++ EvalDll.
* CPPEvalExtendedClient: this sample uses the C++ extended Eval interface in EvalDll to evaluate a RNN model.
* CSEvalClient: this sample uses the C# EvalDll (only for Windows). It uses the CNTK EvalDll Nuget Package.

After a successful build, the executable is saved under the $(SolutionDir)..\..$(Platform)$(ProjectName).$(Configuration)\ folder, e.g. ..\..\X64\CPPEvalClient.Release\CppEvalClient.exe.
On Linux, please refer to Makefile for building samples. The target name EVAL_CLIENT, and EVAL_EXTENDED_CLIENT are used to build these projects.
