Pose LandMark: Unmanaged Code

[GuillaumeWillefert]

Hi, when i tried to use the CalculatorGraph using this pbtxt:
https://github.com/google/mediapipe/blob/master/mediapipe/modules/pose_landmark/pose_landmark_cpu.pbtxt

I got this problem:

Mediapipe.Net.Core.MediapipeNetException: Exception is thrown in Unmanaged Code
   at Mediapipe.Net.Native.MpReturnCodeExtension.Assert(MpReturnCode code)
   at Mediapipe.Net.Framework.Port.StatusOrPoller`1.Value()
   at PoseTracking.PosesSystem.Call(BitmapSource frame) in [...]\PoseTracking\PosesSystem.cs:line 59

At the line:

OutputStreamPoller<NormalizedLandmarkList> poller = graph.AddOutputStreamPoller<NormalizedLandmarkList>("LANDMARKS").Value();

On:
Working on a WPF Project, with MediaPipe.NET and MediaPipe.NET.Runtime.CPU on Any CPU.

I post rarely issue and i am not sure if i have write like intended.

The file if needed: (Seen than the error can be related on the wrong line, but no solution)
PosesSystem.txt
