rectLabel crash when importing a COCO JSON annotations file

[hqm]

thanks that works! You're awesome!

github browse pager doesn'e seem to let me attach json file, so I'm pasting it below

{ "annotations": [ { "iscrowd": 0, "id": 1, "category_id": 1, "segmentation": [ 479, 324, 505, 645, 817, 570, 793, 183 ], "bbox": [ 479, 183, 339, 463 ], "image_id": 1 }, { "iscrowd": 0, "id": 2, "category_id": 1, "segmentation": [ 479, 324, 505, 645, 817, 570, 793, 183 ], "bbox": [ 479, 183, 339, 463 ], "image_id": 2 }, { "iscrowd": 0, "id": 3, "category_id": 1, "segmentation": [ 640, 360, 640, 720, 1280, 720, 1280, 360 ], "bbox": [ 640, 360, 641, 361 ], "image_id": 3 }, { "iscrowd": 0, "id": 4, "category_id": 1, "segmentation": [ 640, 360, 640, 720, 1280, 720, 1280, 360 ], "bbox": [ 640, 360, 641, 361 ], "image_id": 4 }, { "iscrowd": 0, "id": 5, "category_id": 1, "segmentation": [ 640, 360, 640, 720, 1280, 720, 1280, 360 ], "bbox": [ 640, 360, 641, 361 ], "image_id": 5 } ], "images": [ { "file_name": "value-add_2023-03-11T11:47:17.330Z_label_001_frame0.jpg", "id": 1, "width": 1920, "height": 1080 }, { "file_name": "value-add_2023-03-11T11:47:17.330Z_label_001_frame70.jpg", "id": 2, "width": 1920, "height": 1080 }, { "file_name": "value-add_2023-03-11T12:26:43.580Z_label_000_frame741.jpg", "id": 3, "width": 1920, "height": 1080 }, { "file_name": "value-add_2023-03-11T12:29:33.578Z_label_001_frame5.jpg", "id": 4, "width": 1920, "height": 1080 }, { "file_name": "value-add_2023-03-11T12:29:33.578Z_label_001_frame372.jpg", "id": 5, "width": 1920, "height": 1080 } ], "categories": [ { "id": 1, "name": "value-add", "supercategory": "value-add" } ] }

Thanks for reporting the issue and the detailed JSON file.
In the COCO format, the segmentation should be a polygon array.
https://cocodataset.org/#format-data

If you add [] to your segmentation array, RectLabel can import the file.
"segmentation": [[479, 324, 505, 645, 817, 570, 793, 183]],

[ryouchinsa]

Currently RectLabel can import from a single polygon array.

"segmentation": [479, 324, 505, 645, 817, 570, 793, 183],
