View dataset with fiftyone

[robmarkcole]

Just a little tip, but fiftyone can be used to view the dataset - just required updating the annotation file slightly:

import json
import fiftyone as fo

annots = json.load(open("dataset/SateAirports/annotations.json"))

def update_filename_to_png(annots: dict):
    for image in annots['images']:
        image['file_name'] = image['file_name'].replace('tif','png')
    return annots

annots_png = update_filename_to_png(annots)
json.dump(annots_png, open("dataset/SateAirports/annotations_png.json", 'w'))

coco_dataset = fo.Dataset.from_dir(
    dataset_type=fo.types.COCODetectionDataset,
    data_path='dataset/SateAirports/PNGImages',
    labels_path="dataset/SateAirports/annotations_png.json",
    include_id=True,
)

session = fo.launch_app(coco_dataset)
