The Cloud Vision API calling using Python

Let's create a new Python script (or Jupyter notebook). In order to use the Cloud Vision API, we first need to import the Cloud Vision Client library.

1. To do this, we use the following code:

from google.cloud import vision

2. With this, we're ready to move on and use the client library. In our example, we will annotate an image. The image annotation service is provided by the imageAnnotatorClient() function in the Vision library. We will create an object of the method:

client = vision.ImageAnnotatorClient()

3. Now, let's load the file to be tested for annotation into the program:

with open("test.jpg", 'rb') as image_file:    content = image_file.read()

Note that you should have the test.jpg file in the ...
