title: K fold cross validation in yolo v4 with darknet
body: <p>I am new to the field of deep learning. I need to test a trained model with darknet neural network, using yolo v4.
  During the training I performed the division of the dataset into 80% training test and 20% test set.
  I would like to know if there was a way to use the k fold cross validation methodology with yolo.</p>
