You mentioned assigning "Cognitive Services Custom Vision Contributor", but for Image Analysis, the recommended role is "Cognitive Services User"

enter image description here

  • Open Microsoft Entra ID now, click on App registrations go to API permissions click Add a permission. Select Azure AI Services and Delegated permissions. Add CognitiveServices.ComputerVision. click Grant admin consent.

Install pip install azure-ai-vision azure-identity python Library.

Code:

from azure.identity import ClientSecretCredential
from azure.ai.vision.imageanalysis import ImageAnalysisClient

# Replace with your Microsoft Entra ID details
TENANT_ID = "your-tenant-id"
CLIENT_ID = "your-client-id"
CLIENT_SECRET = "your-client-secret"
ENDPOINT = "https://your-resource-name.cognitiveservices.azure.com/"

# Authenticate using Microsoft Entra ID
credential = ClientSecretCredential(
    tenant_id=TENANT_ID,
    client_id=CLIENT_ID,
    client_secret=CLIENT_SECRET
)

# Initialize Image Analysis Client
client = ImageAnalysisClient(
    endpoint=ENDPOINT,
    credential=credential,
)

# Test authentication
token = credential.get_token("https://cognitiveservices.azure.com/.default")
print("Access Token:", token.token)  # Should print a valid token
