IBM Software Hub Version 5.1.0

A new version of Watson Machine Learning was released in December 2024 with IBM Software Hub 5.1.0.

Operand version: 5.1.0

This release includes the following changes:

New features
This release of Watson Machine Learning includes the following features:
Deploy multi-source SPSS Modeler flows
You can now create deployments for SPSS Modeler flows that use multiple input streams to provide data to the model.
Use GPU inferencing and create deep learning experiments with Watson Machine Learning
You no longer need Watson Machine Learning Accelerator to train deep learning experiments or use GPU inferencing. If you have the IBM Software Hub scheduling service and Watson Machine Learning installed, you can now train a neural network using the Deep learning experiment builder in Watson Studio and use the power of GPU inferencing. Train deeper neural networks and explore more complicated hyperparameter spaces.
New runtime available to deploy AI asset on s390x hardware
You can now use Runtime 24.1 to deploy AI assets on s390x hardware.
To read more about these features, see:
Updates
The following updates were introduced in this release:
Discontinuation of Runtime 23.1 for deploying AI assets
Model types and software specifications that are deployed with Runtime 23.1 will no longer work. To prevent disruption, update your model types and software specifications to use Runtime 24.1.
Constriction of runtimes for R Scripts and R Shiny applications to deploy AI assets
Model types and software specifications for R Scripts and R Shiny applications that are deployed with Runtime 23.1 are constricted and will be discontinued in the future. To prevent disruption, update your model types and software specifications to use Runtime 24.1.
