Classes
GeneratedImage
GeneratedImage(
image_bytes: bytes, generation_parameters: typing.Dict[str, typing.Any]
)
Generated image.
Image
Image(image_bytes: bytes)

ImageCaptioningModel
ImageCaptioningModel(model_id: str, endpoint_name: typing.Optional[str] = None)
Generates captions from image.
Examples::
model = ImageCaptioningModel.from_pretrained("imagetext@001")
image = Image.load_from_file("image.png")
captions = model.get_captions(
image=image,
# Optional:
number_of_results=1,
language="en",
)
ImageGenerationModel
ImageGenerationModel(model_id: str, endpoint_name: typing.Optional[str] = None)

response = model.generate_images(
prompt="Astronaut riding a horse",
# Optional:
number_of_images=1,
width=1024,
width=768,
seed=0,
)
response[0].show()
