Hello, at the time of training, I get the following: WARNING: tensorflow: Compiled the loaded model, but the compiled metrics have yet to be built. model.compile_metrics will be empty until you train or evaluate the model.

And also in the mAP evaluation it shows me the following: Evaluation samples: 59 Using IoU: 0.5 Using Object Threshold: 0.3 Using Non-Maximum Suppression: 0.5 hololens: 0.0000 mAP: 0.0000

[{‘model_file’: ‘/content/drive/MyDrive/hololens/models/detection_model-ex-001–loss-0037.935.h5’, ‘using_iou’: 0.5, ‘using_object_threshold’: 0.3, ‘using_non_maximum_suppression’: 0.5, ‘average_precision’: {‘hololens’: 0.0}, ‘evaluation_samples’: 59, ‘map’: 0.0}]
