c# Wrapper for CNTK steps

Question

I'm having some issues at running CNTK on c# wrapper. I see rold2007 had success on doing the same thing. There got to be something simple that I missed. Any advice would be greatly appreciated.

The steps I used are as follow:

1. use the source code from C#
2. generate a new dos application and copy the new code to it.
3. building the program, the following error occurred at line
   using (var model = new IEvaluateModelManagedF()) Wit error message:

Severity Code Description Project File Line Suppression State Error CS0246 The type or namespace name 'IEvaluateModelManagedF' could not be found (are you missing a using directive or an assembly reference?)

VS version: vs community 2015 OS: windows 10. CNTK: Downloaded binary. Able to run a sample program.

Answer 1

Your project needs to reference EvalWrapper.dll. In the same directory as the DLL, you need to have a list of other DLLs that are used. See the detailed discussion on the CNTK GitHub page. If you are running a CPU-only build, this is the list of DLLs:

• EvalDll.dll
• EvalWrapper.dll
• libacml_mp_dll.dll
• libifcoremd.dll
• libifportmd.dll
• libiomp5md.dll
• libmmd.dll
• Math.dll
• svml_dispmd.dll

Update

CNTK has switched from ACML to Intel MKL as of August 2016 (see Release Notes). After this change, the list of required DLLs is

• EvalDll.dll
• EvalDll.lib
• EvalWrapper.dll
• Math.dll
• libiomp5md.dll
• mkl_cntk_p.dll
