EvalDLL evaluation on Linux

  • Article

The EvalDll library on Linux is provided as a C++ library.

The usage pattern for evaluation is the following:

  1. Get an instance of the evaluation engine either using GetEvalF() (for the float data type) or GetEvalD() (for the double data type).
  2. Load the model (or create the network) in the evaluation engine.
  3. Evaluate some input against the model and obtain the corresponding output.
  4. Dispose the model when done.

The evaluation library, Cntk.Eval, can be found under cntk/lib in the CNTK binary package. If you build CNTK from source code, The shared library Cntk.Eval is available in the lib folder of the build directory.

Any program using the evaluation library needs to link the libraries Cntk.Core and Cntk.Math, e.g.

-lCntk.Eval-<VERSION> -lCntk.Math-<VERSION>

, and set the appropriate search path for these libraries. Please use the same build flavor (Debug/Release) and the same compiler version as the one used to create the libraries. The CPPEvalClient in the CNTK source code illustrates the usage pattern in Linux. The Makefile contains the target EVAL_SAMPLE_CLIENT showing how to build the example.
