Hi Zhang, another question, did you deploy your Azure Databricks and Machine Learning Service in different resource groups? If so, that went wrong.
I just created an additional parameter databricks_grp in project/services/10_prepEnvModelCreation.py to fix this such different resource groups can be used.
You need to delete your Azure Databricks compute in Machine Learning Service Workspace, add the new file project/services/10_prepEnvModelCreation.py to your project, fill in parameter databricks_grp and then rerun the pipeline. Let me know.
