1.4 About the Python Components and Libraries in OML4Py

OML4Py requires an installation of Python, a number of Python libraries, as well as the OML4Py components.

• In Oracle Autonomous Database, OML4Py is already installed. The OML4Py installation includes Python, additional required Python libraries, and the OML4Py server components. A Python interpreter is included with Oracle Machine Learning Notebooks in Autonomous Database.

• You can install OML4Py in an on-premises Oracle Database. In this case, you must install Python, the additional required Python libraries, the OML4Py server components, and an OML4Py client. See Install OML4Py for On-Premises Databases.
