4.1 About Oracle Machine Learning Notebooks

Oracle Machine Learning Notebooks is an enhanced web-based notebook platform for data engineers, data analyst, R and Python users, and data scientists. You can write code, text, create visualizations, and perform data analytics including machine learning. Notebooks work with interpreters in the back-end.

In Oracle Machine Learning, notebooks are available in a project within a workspace, where you can create, edit, delete, copy, move, and even save notebooks as templates. A notebook can contain many paragraphs. A paragraph is a notebook component where you can write and run SQL statements, PL/SQL scripts, R and Python code, and conda instructions. You can run paragraphs individually or, run all the paragraphs in a notebook using a single button. A paragraph has an input section and an output section. In the input section, specify the interpreter to run along with the code or text. This information is sent to the interpreter to be run. In the output section, the results of the interpreter are provided.

Note:

There is a single namespace for both the original notebooks and the new notebooks. You cannot have a notebook with the same name in both notebook lists. A notebook copied from the original interface to the new will have _new appended to it.
