[manta]

When running this code:

img = self.wandb.Image(
            orgimg,
            boxes={
                "predictions": {
                    "box_data": [
                        {
                            "position": {
                                "minX": 0.1,
                                "maxX": 0.3,
                                "minY": 0.2,
                                "maxY": 0.4
                            },
                            "class_id": 0,
                            "box_caption": "a person",
                            "domain": "fraction",
                            "scores": {"conf": 0.95}
                        }
                    ],
                    "class_labels": {
                        0: "person",
                        1: "robot",
                        2: "object"
                    }
