ZenML is an extensible, open-source MLOps framework designed to create reproducible machine learning pipelines. It provides a structured way to manage the entire machine learning lifecycle, from data ingestion to model deployment. ZenML integrates seamlessly with popular ML tools and platforms, making it easier for data scientists and engineers to collaborate and scale their workflows.
When working with ZenML, you might encounter an error message indicating an UNSUPPORTED_DATABASE_TYPE. This error typically arises when configuring the backend database for ZenML metadata storage. The symptom is usually a failure to connect or initialize the database, accompanied by a specific error message pointing to the unsupported database type.
The UNSUPPORTED_DATABASE_TYPE error occurs when the database type specified in your ZenML configuration is not among the supported options. ZenML relies on certain databases to store metadata and other critical information, and using an unsupported type can disrupt this process.
As of the latest ZenML release, the supported database types include:
For a complete list of supported databases, refer to the ZenML documentation.
First, check your ZenML configuration file (usually zenml.yaml) to ensure that the database type specified is correct. Open the configuration file and locate the database settings:
database:
type: postgresql
host: localhost
port: 5432
username: your_username
password: your_password
Ensure that the type field is set to one of the supported database types.
If the database type is incorrect, update it to a supported type. For example, if you intended to use PostgreSQL, ensure the type is set to postgresql.
After updating the configuration, restart any ZenML services or applications to apply the changes. This can typically be done using:
zenml up
This command will restart ZenML and apply the new configuration settings.
