sergeipetrov/zero-shot-image-classification

Fork of openai/clip-vit-base-patch32 for a zero-sho-image-classification Inference endpoint.

This repository implements a custom task for zero-shot-image-classification for 🤗 Inference Endpoints. The code for the customized pipeline is in the pipeline.py.

To use deploy this model a an Inference Endpoint you have to select Custom as task to use the pipeline.py file. -> double check if it is selected

expected Request payload

{
  "image": "/9j/4AAQSkZJRgABAQEBLAEsAAD/2wBDAAMCAgICAgMC....", // base64 image as bytes
  "candiates":["sea","palace","car","ship"]
}

below is an example on how to run a request using Python and requests.

Run Request

1. prepare an image.

!wget https://huggingface.co/datasets/mishig/sample_images/resolve/main/palace.jpg

2. run request

import json
from typing import List
import requests as r
import base64

ENDPOINT_URL = ""
HF_TOKEN = ""


def predict(path_to_image: str = None, candiates: List[str] = None):
    with open(path_to_image, "rb") as i:
        b64 = base64.b64encode(i.read())

    payload = {"inputs": {"image": b64.decode("utf-8"), "candiates": candiates}}
    response = r.post(
        ENDPOINT_URL, headers={"Authorization": f"Bearer {HF_TOKEN}"}, json=payload
    )
    return response.json()


prediction = predict(
    path_to_image="palace.jpg", candiates=["sea", "palace", "car", "ship"]
)

expected output
