I just want to add to the other comments that Polyaxon focuses on different aspects of machine learning reproducibility than Pachyderm, although Polyaxon will be providing a very simple pipelining abstraction to start experiments based on previous jobs, triggers, or schedules, or provide the possibility to run post-experiment jobs. It will not focus on data provenance the same way Pachyderm does. In fact, Polyaxon and Pachyderm could be used together.
