model = ImageTextModel.from_pretrained("imagetext@001")
image = Image.load_from_file("image.png")

captions = model.get_captions(
    image=image,
    # Optional:
    number_of_results=1,
    language="en",
)

    image=image,
    question="What color is the car in this image?",

)

Methods

ImageTextModel

ImageTextModel(model_id: str, endpoint_name: typing.Optional[str] = None)
