Create ML app can not stop training

I would like to train a model for object detection. When the training iteration reached to the maximum I set, Create ML app is still in training process and I don't see any trained model.

I tested on both Xcode 11.5 and Xcode 12.0 beta built in Create ML app. The issue is still exist.

So just for testing, I set the maximum iteration to 20, no model find when reached to 20 iterations.

Anyone has a solution?
