Cloud Natural Language API Client Library for Python

Cloud Natural Language API: Provides natural language understanding technologies to developers. Examples include sentiment analysis, entity recognition, entity sentiment analysis, and text annotations.

System requirements

Installing the client library

You can either use a package manager or download and install the Python client library manually:

Managed installation

Use pip or setuptools to manage your installation (you might need to run sudo first):

  • pip (preferred):
    $ pip install --upgrade google-api-python-client
  • Setuptools: Use the easy_install tool included in the setuptools package:
    $ easy_install --upgrade google-api-python-client

Manual installation

Download the latest client library for Python, unpack the code, and run python install

App Engine

Because the Python client libraries are not installed in the App Engine Python runtime environment, they must be vendored into your application just like third-party libraries.
