1.3.5.2.1 Prerequisites for Installing the Python Client

You must ensure that the following prerequisites are met before you install the Python client:

1. Make sure that the following softwares are installed on your system:
   • Oracle JDK 8 or later
   • Python 3.5 or later

     To verify you are using the right version of the Python client, run the following command:

     $> python3 --version
     Python 3.6.1

   Note:

   Python 2.x is not supported.

   For more information on installing Python 3 on Oracle Linux, see Python for Oracle Linux.

2. Make sure that the following Python packages are installed on your system:
   • python3-devel
   • pyjnius-1.3.0.zip
   • six-1.14.0.zip
   • Cython-0.29.17.zip
   • pandas
   1. To check the list of packages installed in your system and to identify the missing packages, execute the following command:

      pip3 list

      The result may be as shown:

      Package         Version
      --------------- -------
      Cython          0.29.17
      numpy           1.19.5
      pip             21.1
      pyjnius         1.3.0
      six             1.14.0

      The result shows that the pandas module is missing.
   2. Navigate to your Oracle Graph Client installation directory.
      • For a server and client installed on the same machine, the Oracle Graph Client installation directory is located at:

        /opt/oracle/graph/client/python

      • For a client installation using a remote server, the Oracle Graph Client installation directory is located at:

        <pgx_client_dir>/python

        where <pgx_client_dir> is the directory where you extracted the oracle-graph-client-21.2.zip file.

   3. Install the missing dependencies by executing the following command as root:

      sudo pip3 install --user <missing_module>

      where <missing_module> is the missing dependency module that need to be installed.

      For example to install pyjnius-1.3.0.zip:

      sudo pip3 install --user pyjnius-1.3.0.zip
