Oracle Cloud Infrastructure Documentation / Release Notes

Improvements to the Notebook Session Environment

The Notebook Session environment includes the following changes:

  • The home folder is now backed by block volume. You can now save all your files to the /home/datascience folder, and they persist when you deactivate and activate your sessions. The block_storage folder no longer exists. The Oracle Cloud Infrastructure keys can be saved directly to the ~/.oci folder, and no symbolic links are required. Note that the ads-examples directory in the home folder is a symbolic link to the /opt/notebooks/ads-examples. Any changes made in ads-examples are not saved if you deactivate a notebook.
  • Each new notebook that is launched has a pre-populated accordion-style cell containing useful tips.
  • These are the packages that changed:

fdk = 0.1.12

pandas-datareader = 0.8.1

py-cpuinfo = 5.0

Oracle Accelerated Data Science (ADS) SDK

  • The ADS integration with Oracle Cloud Infrastructure Data Flow service provides a more efficient and convenient to launch a Spark application and run Spark jobs.
  • show_in_notebook() is changed to remove “head” from accordion and replace it with dataset “warnings”.
  • get_recommendations() is deprecated and replaced with suggest_recommendations(), which returns a pandas dataframe with all the recommendations and suggested code to implement each action.
  • A progress indication of Autonomous Data Warehouse reads has been added.

For details about AutoML and MLX upgrades, see the ADS Release Notes.

Notebooks

  • A new notebook is included in the ads-examples directory to demonstrate ADS and Data Flow integration.
  • A new notebook is included in the ads-examples directory that demonstrates advanced custom scoring functions within AutoML by implementing custom class weights.
  • A new version of the notebook example for deployment to Functions and API Gateway is now using Cloud Shell.
  • Significant improvements to existing ADS Notebooks were made.
