Deploying NumPy code in the Google cloud

Deploying GAE applications is pretty easy. For NumPy an extra configuration step is required, but that will take only minutes.

How to do it...

Let's create a new application.

1. Create a new application.

   Create a new application with the launcher (File | New Application). Name it numpycloud. This will create a folder with the same name containing the following files:

   • app.yaml: YAML application configuration file

   • favicon.ico: Icon image

   • index.yaml: Auto generated file

   • main.py: Main entry point for the web application

2. Add NumPy to the libraries.

   First, we need to let GAE know that we want to use NumPy. Add the following lines to the app.yaml configuration file in the libraries section:

   - name: NumPy
     version: "1.6.1"

   The configuration file should have the following contents:

   application: numpycloud
   version: 1
   runtime: python27
   api_version: 1
   threadsafe: yes
   
   handlers:
   - url: /favicon\.ico
     static_files: favicon.ico
     upload: favicon\.ico
   
   - url: .*
     script...
