Wrong timeofday flag in labels

[vincenzosantopietro]

I'm currently exploring data of the bdd100k dataset, i've experienced a very strange situation. I've filtered out all images that are not containing the "daytime" label for timeofday.

I still see some night images in the resulting set of images.
Some examples:

{"name": "2b2c44c7-958f0ba8.jpg", "attributes": {"weather": "undefined", "scene": "city street", "timeofday": "daytime"}

{"name": "a535e685-201c994e.jpg", "attributes": {"weather": "clear", "scene": "highway", "timeofday": "daytime"}

Check the images I've pasted here and you can see they're both night images.
How is this happening? Bad manual labeling?

I actually can not tell how many night images are "misclassified".
