For IBM PowerAI 1.6.0 andWatson Machine Learning Community Edition 1.6.1 :

Upgrade to WML CE 1.6.2, which includes the fixes. See <https://www.ibm.com/support/knowledgecenter/SS5SF7&gt; for upgrading instructions.

ForWatson Machine Learning Community Edition 1.6.2 :

For installing WML CE from scratch

New installations of WML CE include all security fixes. See <https://www.ibm.com/support/knowledgecenter/SS5SF7&gt; for installation instructions.

Updating an existing WML CE installation

It is recommended to keep packages up to date. To update all packages to the latest versions use:

conda update --all

To update individual packages, use the package name:

conda update tensorboard

If you have previously installed WML CE using the powerai meta-package, you can also use that to update to the latest packages.

conda update powerai
