Maurizio,
The requirement that you reference is no longer in place because the ADK and Developer Edition are both in General Availability now. Take a look at the updated instructions in the ADK documentation for doing the install here. It has been updated and is really nice and easy to follow now.
Some things to note:
- You will need access to a wxO environment either on AWS or IBM Cloud (see options for wxO environment access here).
- Updated your ADK (i.e. pip install --upgrade ibm-watsonx-orchestrate or pip install --upgrade ibm-watsonx-orchestrate==1.8.1 for more control)
- Ensure you local laptop has the proper container engine prerequisites. IBM'ers should use Rancher Desktop. Other options include Docker Desktop, Podman, and more.
