call the google vision api in python

To call the Google Vision API in Python, you first need to set up a Google Cloud account, enable billing, create a new project, and then enable the Vision API for that project. Once that is done, you can start using the Vision API in your Python code.

You will need to install the google-cloud-vision Python package. You can do this using pip:


main.py
pip install google-cloud-vision
32 chars
2 lines

After installing the package, you can use the following code to call the Vision API:


main.py
from google.cloud import vision
from google.cloud.vision import types
import io
import os

# Set up the client
os.environ['GOOGLE_APPLICATION_CREDENTIALS'] = r'path\to\service\account\key.json'
client = vision.ImageAnnotatorClient()

# Load the image into memory
with io.open('path\to\image.jpg', 'rb') as image_file:
    content = image_file.read()
image = types.Image(content=content)

# Perform the API request
response = client.label_detection(image=image)
labels = response.label_annotations

# Print the labels
for label in labels:
    print(label.description)
567 chars
22 lines

This code loads an image from disk, performs a label detection API request, and then prints the labels to the console.
