Reference a third-party package in a PyODPS node

Depend on common Python scripts

1. Go to the DataStudio page.
   1. Log on to the DataWorks console.
   2. In the left-side navigation pane, click Workspaces.
   3. In the top navigation bar, select the region where your workspace resides, find the workspace, and then click Data Analytics in the Actions column.
2. Create a Python resource.
   1. On the Data Development tab, move the pointer over the icon and choose MaxCompute > Resources > Python.
      Alternatively, you can click a workflow in the Business process section, right-click MaxCompute, and then choose New > Resource > Python.
   2. In the Create Resource dialog box, set the Resource Name and Location parameters. For example, set the Resource Name parameter to pyodps_packagetest.py.
      Notice The resource name can contain letters, digits, periods (.), underscores (_), and hyphens (-), and must end with .py.
   3. Click Confirm.
   4. On the configuration tab of the created Python resource, enter the code of the third-party package that is to be referenced. In this example, enter the following code:

      # import os
      # print os.getcwd()
      # print os.path.abspath('.')
      # print os.path.abspath('..')
      # print os.path.abspath(os.curdir)
      
      def printname():
          print 'test2'
      print 123

   5. Click the icon in the top toolbar.
3. Create a PyODPS 2 node.
   1. Click the required workflow under Business Flow. Right-click MaxCompute and choose Create > PyODPS 2.
   2. In the Create Node dialog box, set the Node Name and Location parameters. For example, set the Node Name parameter to pyodps_testpackage.
      Note The node name must be 1 to 128 characters in length. It can contain letters, digits, underscores (_), and periods (.).
   3. Click Commit.
4. Open the configuration tab of the PyODPS 2 node. Right-click the name of the created Python resource and select Insert Resource Path.
   After the resource is referenced, the ##@resource_reference{"pyodps_packagetest.py"} statement is automatically written in the code editor of the PyODPS 2 node.
5. Enter the code of the third-party package that is to be referenced in the code editor of the PyODPS 2 node. In this example, enter the following code:

   ##@resource_reference{"pyodps_packagetest.py"} # This statement is required to reference the created Python resource.
   
   import sys
   import os
   sys.path.append(os.path.dirname(os.path.abspath('pyodps_packagetest.py'))) # Import the resource to the workspace.
   import pyodps_packagetest # Reference the resource. The .py suffix of the resource name must be deleted.
   pyodps_packagetest.printname() # Call the method.

6. Click the icon in the top toolbar and view the results on the Runtime Log tab in the lower part of the page.
