Python

Um mit Python auf die Ultralytics HUB Inference API zuzugreifen, verwende den folgenden Code:

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())

Hinweis

Ersetze MODEL_ID mit der gewünschten Modell-ID, API_KEY mit deinem aktuellen API-Schlüssel, und path/to/image.jpg mit dem Pfad zu dem Bild, für das du die Inferenz durchführen möchtest.

cURL

Um mit cURL auf die Ultralytics HUB Inference API zuzugreifen, verwende den folgenden Code:

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"

Hinweis

Ersetze MODEL_ID mit der gewünschten Modell-ID, API_KEY mit deinem aktuellen API-Schlüssel, und path/to/image.jpg mit dem Pfad zu dem Bild, für das du die Inferenz durchführen möchtest.

Argumente

In der folgenden Tabelle findest du eine vollständige Liste der verfügbaren Schlussfolgerungsargumente.

Argument	Standard	Typ	Beschreibung
`image`		`image`	Bilddatei, die für die Inferenz verwendet werden soll.
`url`		`str`	URL des Bildes, wenn keine Datei übergeben wird.
`size`	`640`	`int`	Größe des Eingabebildes, gültiger Bereich ist `32` - `1280` bildpunkte.
`confidence`	`0.25`	`float`	Konfidenzschwelle für Vorhersagen, gültiger Bereich `0.01` - `1.0`.
`iou`	`0.45`	`float`	Schwellenwert für Schnittmenge über Union (IoU), gültiger Bereich `0.0` - `0.95`.

Antwort

Die Ultralytics HUB Inference API gibt eine JSON-Antwort zurück.
