i am sorry it was never an issue at all my bad i downloaded the shape_predictor_68_face_landmarks.dat but it wasn't complete i downloaded it again everything is working fine thank you

I get same error When I use:

var directory = Path.GetFullPath("models");
FaceRecognition.Create(directory);

I downloaded the .dat files again, but same error occurs.
Anyone any idea what I can try next?

hi, could you show me the model file full path?
Dlib uses std::string rather than std::wstring.
so it contains certain character and it could fail searching file.

This was exactly it, thanks! Had the 'ë' character somewhere in there. Working perfectly now!
