I am trying to implement more labels into my YoloV4 CNN, but I am getting this error message.
![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/1202583/image.png)
I am not really sure what is going on, I have tried to go into the problem areas and find something out, but no luck. not really sure what the gTruthClassNames is, but I think thats my problem. I would attach my code but it is to large (any way around that)
Could this also be caused by not using one of the class names not being used, is there a way around this?
Here is my class names
className = {'Front-Windscreen-Damage'...
,'Headlight-Damage'...
,'Major-Rear-Bumper-Dent'...
,'Rear-windscreen-Damage'...
,'RunningBoard-Dent'...
,'Sidemirror-Damage'...
,'Signlight-Damage'...
,'Taillight-Damage'...
,'bonnet-dent'...
,'doorouter-dent'...
,'fender-dent'...
,'front-bumper-dent'...
,'medium-Bodypanel-Dent'...
,'pillar-dent'...
,'quaterpanel-dent'...
,'rear-bumper-dent'...
,'roof-dent'} ;
These are the imputs, Ill share a link to my workspace below, it goes to my google drive as it is over 5mb. (Not sure if sharing like this is allowed, remove is not)...
[detector,info] = trainYOLOv4ObjectDetector(augmentedTrainingData,detector,options);
Thanks everyone!

This error happens because the inputs to strcmp are incompatible sizes.
Example 1: both inputs the same size (works):
a = {'baba', 'booey'};
b = {'barbara', 'booey'};
strcmp(a,b) % works
Example 2: one input a scalar, one non-scalar (works):
a = {'baba'};
b = {'barbara', 'booey'};
strcmp(a,b) % works
Example 3: non-scalar inputs of different sizes (error):
a = {'baba', 'booey', 'mountain'};
b = {'barbara', 'booey'};
strcmp(a,b) % error
This means that, in your case, gTruthClassNames and detectorClassNames are non-scalars with different sizes. I'm not able to say why that is or what you should do about it though.
