dot indexing not supported for this type variable

I have a code and I have been getting "dot indexing not supported for this type variable" on two lines :

networkInputSize = network.Layers(this.LayerIndices.ImageLayerIdx).InputSize;

and

params = this.parseDetectInputs(I,varargin{:});

Is there any way to solve this problem?

You appear to be passing in something that is not a valid yolo network. In particular, part of it might be empty instead of having data, or part of it might be a numeric matrix instead of being a correct data structure.

@Marwan Abduljawad, can you provide the actual code & any required attachments which is causing the mentioned error?
