Yes, I'm using the recognize-blends Tcl command .I got inside the recogniser.Perform function.

this is some debugging results, I'm not sure what they mean.

I went into the recognizer.Perform function inside, see the last obtained result id is empty

into the GetFaceIndices function found that m_data is empty,

it should be featureRes caused,

I went into the extractor.Perform(m_aag, featureRes, filter) function, found that all the face into the if ( !aag->HasNodeAttributes(fid) ) judgement, and then execute continue; can not enter the next TColStd_PackedMapOfInteger &
feature = result->FindFeature( type, attr->GetFeatureId() ); function, so there is no data for m_data,but I don't understand what is the direct cause of this problem
