Observa: Ultralytics Passo a passo da API de inferência do HUB

Python

Para aceder à API de inferência do Ultralytics HUB utilizando Python, utiliza o seguinte código:

import requests

# API URL, use actual MODEL_ID
url = "https://api.ultralytics.com/v1/predict/MODEL_ID"

# Headers, use actual API_KEY
headers = {"x-api-key": "API_KEY"}

# Inference arguments (optional)
data = {"size": 640, "confidence": 0.25, "iou": 0.45}

# Load image and send request
with open("path/to/image.jpg", "rb") as image_file:
    files = {"image": image_file}
    response = requests.post(url, headers=headers, files=files, data=data)

print(response.json())

Nota

Substitui MODEL_ID com o ID do modelo pretendido, API_KEY com a tua chave API real, e path/to/image.jpg com o caminho para a imagem em que queres fazer a inferência.

cURL

Para aceder à API de inferência do Ultralytics HUB utilizando cURL, utiliza o seguinte código:

curl -X POST "https://api.ultralytics.com/v1/predict/MODEL_ID" \
    -H "x-api-key: API_KEY" \
    -F "image=@/path/to/image.jpg" \
    -F "size=640" \
    -F "confidence=0.25" \
    -F "iou=0.45"

Nota

Substitui MODEL_ID com o ID do modelo pretendido, API_KEY com a tua chave API real, e path/to/image.jpg com o caminho para a imagem em que queres fazer a inferência.
