    oidv6 downloader en --dataset ./openimages --type_data train --classes Turban --limit 1000 --yes

    So to resolve that i manually extracted the Class Code from class-descriptions.csv using:

    turban_id = class_list[class_list['class']=='Turban']['id'].item()

    And images that matched that class code from the oidv7-train-annotations-human-imagelabels.csv to get the image_id

    img_id = df[(df['LabelName'] == turban_id) & (df['Confidence'] > 0.5)]['ImageID'].item

    Finally I tried to download image using URL fromulated as:

    url = f"https://storage.googleapis.com/openimages/v7/oidv7-images/{split}/{img_id}.jpg"

    Where,

    • split = train/test/validation

    But i couldn't get access: ERROR: 403 Anonymous caller does not have storage.objects.get access to the Google Cloud Storage object. Permission 'storage.objects.get' denied on resource (or it may not exist).

    I was hoping there would be a way to download only a select few images given i knew what their image_ids were
