sample running code

with python

from transformers import pipeline

device = torch.device("cuda" if torch.cuda.is_available() else "cpu")
FlowerCaptioner = pipeline("image-to-text", model="cristianglezm/ViT-GPT2-FlowerCaptioner", device=device)
FlowerCaptioner(["flower1.png"])
# A flower with 12 petals in a smooth gradient of green and blue. 
# The center is green with black accents. The stem is long and green.

with javascript

import { pipeline } from '@xenova/transformers';

// Allocate a pipeline for image-to-text
let pipe = await pipeline('image-to-text', 'cristianglezm/ViT-GPT2-FlowerCaptioner-ONNX');

let out = await pipe('flower image url');
// A flower with 12 petals in a smooth gradient of green and blue. 
// The center is green with black accents. The stem is long and green.
