Looks like there is a typo in the image classification recipe on the doc page
The options should be
OPTIONS = [
{"id": 0, "text": "Ray Ban Wayfarer (Original)"},
{"id": 1, "text": "Ray Ban Wayfarer (New)"},
{"id": 2, "text": "Ray Ban Clubmaster (Classic)"},
{"id": 3, "text": "Ray Ban Aviator (Classic)"},
{"id": -1, "text": "Other model"}
]
is missing the ":" after the 0 in the first option line
