Run the pipeline and return a URL pointing to the experiment-visualization page
Executes a pipeline represented by a set of Producer instances Inspects the meta-info about the pipeline steps (represented by PipelineRunnerSupport interface) and builds a DAG representation of the pipeline. Visualizes the DAG in HTML and stores the HTML page along with the pipeline output. The output location of each pipeline step is not specified by the code that builds the pipeline. Instead, each step's output location is determined by the PipelineRunner based on the Signature of that step. This allows independent processes for pipelines with overlapping steps in their DAGs to re-use past calculations.
