PMML Writer

This nodes writes a PMML model from a PMML model port into a PMML v4.2 compliant file or to a remote location denoted by an URL. If a PMML file from another version is read by the PMML Reader and directly written by this node, it is converted into PMML v4.2. If the model is not valid (unknown data types, etc.) an exception is thrown during execution.

This node can access a variety of different file systems. More information about file handling in KNIME can be found in the official File Handling Guide.

Options

Output location

Select a file to store the PMML model.

Create missing folders

Select if the folders of the selected output location should be created if they do not already exist. If this option is unchecked, the node will fail if a folder does not exist.

If exists

Specify the behavior of the node in case the output file already exists.

Fail: Will issue an error during the node's execution (to prevent unintentional overwrite).
Overwrite: Will replace any existing file.

Validate PMML before export

Select to validate the PMML document that should be written. If it is not compliant with the schema, the node will fail before actually writing.
