Cognitive Services Python SDK Samples

These samples will show you how to get up and running using the Python SDKs for various Cognitive Services services. They'll cover a few rudimentary use cases and hopefully express best practices for interacting with the data from these APIs.

Features

This project framework provides examples for the following services:

Knowledge

• Using the QnA SDK azure-cognitiveservices-knowledge-qnamaker for the QnA API

Language

• Using the LUIS SDK azure-cognitiveservices-language-luis for the LUIS API
• Using the Bing Spell Check SDK azure-cognitiveservices-language-spellcheck for the Bing Spell Check API
• Using the Text Analytics SDK azure-cognitiveservices-language-textanalytics for the Tet Analytics API

Search

• Using the Bing Autosuggest SDK azure-cognitiveservices-search-autosuggest for the Autosuggest API
• Using the Bing Custom Search SDK azure-cognitiveservices-search-customsearch for the Custom Search API
• Using the Bing Custom Image Search SDK azure-cognitiveservices-search-customimagesearch for the Custom Image Search API
• Using the Bing Entity Search SDK azure-cognitiveservices-search-entitysearch for the Entity Search API
• Using the Bing Image Search SDK azure-cognitiveservices-search-imagesearch for the Image Search API
• Using the Bing News Search SDK azure-cognitiveservices-search-newssearch for the News Search API
• Using the Bing Video Search SDK azure-cognitiveservices-search-videosearch for the Video Search API
• Using the Bing Visual Search SDK azure-cognitiveservices-search-visualsearch for the Visual Search API
• Using the Bing Web Search SDK azure-cognitiveservices-search-websearch for the Web Search API

Vision

• Using the Face SDK azure-cognitiveservices-vision-face for the Face API
• Using the Computer Vision SDK azure-cognitiveservices-vision-computervision for the Computer Vision API
• Using the Content Moderator SDK azure-cognitiveservices-vision-contentmoderator for the Content Moderator API
• Using the Custom Vision SDK azure-cognitiveservices-vision-customvision for the Custom Vision API

We provide several meta-packages to help you install several packages at a time. Please note that meta-packages are only recommended for development purpose. It's recommended in production to always pin specific version of individual packages.

Getting Started

Prerequisites

1. A cognitive services API key with which to authenticate the SDK's calls. Sign up here by navigating to the Language or Search services and acquiring an API key. You can get a trial key for free which will expire after 30 days or create a Cognitive Services account on the Azure portal through the Use with an Azure subscription button.

Subscription keys are usually per service. For example, the subscription key for Spell Check will not be the same than Custom Search. Read the previous sign up link or the Azure portal for details on subscription keys.

Installation

1. If you don't already have it, install Python.

   This sample (and the SDK) is compatible with Python 2.7, 3.3, 3.4, 3.5 and 3.6.

2. General recommendation for Python development is to use a Virtual Environment. For more information, see https://docs.python.org/3/tutorial/venv.html

   Install and initialize the virtual environment with the "venv" module on Python 3 (you must install virtualenv for Python 2.7):

   python -m venv mytestenv # Might be "python3" or "py -3.6" depending on your Python installation
   cd mytestenv
   source bin/activate      # Linux shell (Bash, ZSH, etc.) only
   ./scripts/activate       # PowerShell only
   ./scripts/activate.bat   # Windows CMD only
   

Quickstart

1. Clone the repository.

   git clone https://github.com/Azure-Samples/cognitive-services-python-sdk-samples.git
   

2. Install the dependencies using pip.

   cd cognitive-services-python-sdk-samples
   pip install -r requirements.txt
   

3. Set up the environment variable LUIS_SUBSCRIPTION_KEY with your key if you want to execute LUIS tests.

4. Set up the environment variable SPELLCHECK_SUBSCRIPTION_KEY with your key if you want to execute SpellCheck tests.

5. Set up the environment variable TEXTANALYTICS_SUBSCRIPTION_KEY with your key if you want to execute TextAnalytics tests. You might override too TEXTANALYTICS_LOCATION (westcentralus by default).

6. Set up the environment variable AUTOSUGGEST_SUBSCRIPTION_KEY with your key if you want to execute Autosuggest tests.

7. Set up the environment variable CUSTOMSEARCH_SUBSCRIPTION_KEY with your key if you want to execute CustomSearch tests.

8. Set up the environment variable CUSTOMIMAGESEARCH_SUBSCRIPTION_KEY with your key if you want to execute CustomImageSearch tests.

9. Set up the environment variable ENTITYSEARCH_SUBSCRIPTION_KEY with your key if you want to execute EntitySearch tests.

10. Set up the environment variable IMAGESEARCH_SUBSCRIPTION_KEY with your key if you want to execute ImageSearch tests.

11. Set up the environment variable NEWSSEARCH_SUBSCRIPTION_KEY with your key if you want to execute NewsSearch tests.

12. Set up the environment variable VIDEOSEARCH_SUBSCRIPTION_KEY with your key if you want to execute VideoSearch tests.

13. Set up the environment variable VISUALSEARCH_SUBSCRIPTION_KEY with your key if you want to execute VideoSearch tests.

14. Set up the environment variable WEBSEARCH_SUBSCRIPTION_KEY with your key if you want to execute WebSearch tests.

15. Set up the environment variable COMPUTERVISION_SUBSCRIPTION_KEY with your key if you want to execute Computer Vision tests. You might override too COMPUTERVISION_LOCATION (westcentralus by default).

16. Set up the environment variable CONTENTMODERATOR_SUBSCRIPTION_KEY with your key if you want to execute Content Moderator tests. You might override too CONTENTMODERATOR_LOCATION (westcentralus by default).

17. Set up the environment variable CUSTOMVISION_TRAINING_KEY with your key if you want to execute CustomVision Training tests.

18. Set up the environment variable CUSTOMVISION_PREDICTION_KEY with your key if you want to execute CustomVision Prediction tests.

Demo

A demo app is included to show how to use the project.

To run the complete demo, execute python example.py

To run each individual demo, point directly to the file. For example (i.e. not complete list):

2. python samples/language/spellcheck_samples.py
3. python samples/search/entity_search_samples.py
4. python samples/search/video_search_samples.py

To see the code of each example, simply look at the examples in the Samples folder. They are written to be isolated in scope so that you can see only what you're interested in.
