4.1.3.1.1.3 Executing a Pipeline

Use this Execute option to execute pipeline from the pipeline designer page.

To execute the pipeline, follow these steps:

1. On the Pipeline tab, click the Execute icon. The Execute Pipeline pane is displayed.
2. Select the flow, which you want to execute Scoring, Training, and Experimentation. It displays all the keys defined for all the paragraphs in the notebook with a placeholder for providing the values.
   Execution parameters are the parameters defined in the notebook required for execution.
3. In the Execution Parameters, enter the Key and Value.
   The System Parameters also shows the Execution ID, Execution Date, and Execution Batch. These are required for executing all the paragraphs along with other parameters. It also shows from where the parameter comes from as a subscript.
   Save parameters set: These are the set of parameters with a specific value required for an instance of execution. It consists Key and Value. You can save the parameters set that can be used for one execution instance and reuse it for the next execution. It consists of parameters with a specific value to each parameter. Parameters containing no value will not be taken. Each set is identified with a unique code for each objective. While saving the parameter, you have to provide a code for identifying the name and description which is not mandatory. You can save Key Value parameter set using the Save parameter set option. To Save Parameter Set, enter the Threshold Value and Description in the Parameter Set pane.
   Open from saved parameter set: These saved Parameter Set can be selected during the execution. It will replace the values of the parameters from the chosen Parameter Set. Click Open from saved parameter set. The Threshold Code pane is displayed. Select the Parameter Set from the available list. You can select multiple Parameter Set in the same execution instance. In that case, if there are any common keys, value will be replaced with that from the latest Parameter Set selected.
4. Click Add new parameters to add new parameters for execution.

   Note:

   If the parameter is not defined in the notebook, it will not be used for the execution. In case of multi select, if there are common parameters among the chosen scenarios, it will take the value based on the order of selection. that is first chosen scenario parameter will be taken.
5. To view the only required parameters, click Show only required link. Execution will be performed based on the selected links. It filters out all the unused parameters and all the unused parameters for the current execution are displayed with a warning.
