Errors in using Object Detection Using Faster R-CNN Deep Learning example

I wanted to use example 'Object Detection Using Faster R-CNN Deep Learning'

I'll replace the data with about 50 images that I labeled myself,

I'm proceeding but I keep getting stuck here.

trainFaste​rRCNNObjec​tDetector() << There's an error here..

It says "neural networks are not correct."

For your information, it's 'doTraining = true'

It would be the best if you can provide reproducible steps with relevant files. Otherwise, we can never know why your "neural networks are not correct".
