Connector for Python

The Python connector allows the retrieval of output data from a Python Pyro (Python Remote Objects) process.

For Python connectivity, Python must be first installed, together with the latest version of Pyro4. In addition, Pyro must be initiated manually or through using the batch file start_Python_connectivity.bat.

If the scripts utilize additional modules such as Numpy & Scipy in the shipped example, these also need to be installed into the existing Python installation.

Steps:

 

1.     Enter the following properties:

Property

Description

Host

Python Pyro instance host address.

Port

Python Pyro host port. Default is 9090.

HMAC Key

Set to password.

 

2.     Select the Serialization Type: Serpent or Pickle.

·         Serpent – simple serialization library based on ast.literal_eval

·         Pickle – faster serialization but less secure

Modify the configuration.py  file located in ..\Anaconda3\Lib\site-packages\Pyro4 to specify the serialization to be used.

For example, if Pickle is selected, self.SERIALIZER value should be changed to pickle and self.SERIALIZERS_ACCEPTED  value should be changed to include pickle:

 

   NOTE

The Host, Port, HMAC Key, and Serialization Type fields will be hidden if their corresponding properties are set in the Panopticon.properties file.

3.     Date/Time values of output data and Date/Time inputs, where supported, are by default unchanged.

You can opt to define the Show in Timezone and Source Timezone settings.

4.     Enter the required Python script to execute on the active Pyro instance.

5.     Check the Use Apache Arrow box to enable fast serialization of data frames.

6.     Select whether the parameters should be automatically enclosed in quotes by checking the Enclose parameters in quotes box.
