This example demonstrates an ML pipeline which preprocesses data in two concurrent steps, trains two networks, where each
network's training depends upon the completion of its own preprocessed data, and picks the best model. It is implemented
using the [automation.controller.PipelineController](../../../../../references/sdk/automation_controller_pipelinecontroller.md)
using the [PipelineController](../../../../../references/sdk/automation_controller_pipelinecontroller.md)
class.
The pipeline uses four Tasks (each Task is created using a different notebook):

* A training Task ([train_tabular_predictor.ipynb](https://github.com/allegroai/clearml/blob/master/examples/frameworks/pytorch/notebooks/table/train_tabular_predictor.ipynb))
* A better model comparison Task ([pick_best_model.ipynb](https://github.com/allegroai/clearml/blob/master/examples/frameworks/pytorch/notebooks/table/pick_best_model.ipynb))
The `automation.controller.PipelineController` class includes functionality to create a pipeline controller, add steps to the pipeline, pass data from one step to another, control the dependencies of a step beginning only after other steps complete, run the pipeline, wait for it to complete, and cleanup afterwards.
The `PipelineController` class includes functionality to create a pipeline controller, add steps to the pipeline, pass data from one step to another, control the dependencies of a step beginning only after other steps complete, run the pipeline, wait for it to complete, and cleanup afterwards.
In this pipeline example, the data preprocessing Task and training Task are each added to the pipeline twice (each is in two steps). When the pipeline runs, the data preprocessing Task and training Task are cloned twice, and the newly cloned Tasks execute. The Task they are cloned from, called the base Task, does not execute. The pipeline controller passes different data to each cloned Task by overriding parameters. In this way, the same Task can run more than once in the pipeline, but with different data.
