I am following the steps from [https://github.com/opencv/opencv/blob/master/samples/dnn/face\_detector/how\_to\_train\_face\_detector.txt](https://github.com/opencv/opencv/blob/master/samples/dnn/face_detector/how_to_train_face_detector.txt) to train Face detection model on custom dataset.

I am using Ubuntu 20.04 based docker container. I was able to complete all the steps but I am getting in final training step. I am getting this error while doing it:

```

```

I found this [https://github.com/opencv/opencv/pull/14938](https://github.com/opencv/opencv/pull/14938) in opencv but I am not sure what to do. Any help is appreciated. Thanks.

opencv version ? do you use your own protobuf or the 3rdparty one ?

neither ` net.cpp` nor `upgrade_proto.cpp` are part of opencv,  
so where does it come from ?
