Collaboration with ZenML¶
ZenML’s mission is centered on reproducible Machine Learning, with easy access to integrations for your favorite technologies. A key aspect of this mission is the ability to easily collaborate with your team across machines and environments, without sacrifices.
Collaboration with ZenML means shared access to:
Deploying the above in a shared setting makes all experiments within a ZenML repository reproducible and discoverable. This is regardless of which team member ran the corresponding pipelines, and regardless of the environment the experiments were run in.
The Metadata and Artifact Stores respectively, while highly recommended, are not neccessary be shared to ensure collaboration. You could as well share the Git Repository with a committed local pipeline directory and still collaborate using ZenML. However, losing the Artifact and Metadata Store will invalidate all caching, and all pipelines need them to be re-run on every team members local setup. This might have uninteded consequences, so please be careful when setting this up in production.
After ensuring that the above properties are accessible by all team members, any member of the team can create pipelines and experiment at their will.
So if Team Member A creates and pushes a pipeline like so:
training_pipeline = TrainingPipeline(name='Pipeline A') # add steps to the pipeline, not shown here training_pipeline.run()
Then Team Member B can access this pipeline and use it as follows:
from zenml.core.repo.repo import Repository # Get a reference in code to the current repo repo = Repository() pipeline_a = repo.get_pipeline_by_name('Pipeline A') pipeline_a.view_schema() # view schema pipeline_a.view_statistics() # view statistics of the run pipeline_a.view_anomalies() # view anomalies (feature drift etc) pipeline_a.evaluate() # view results
They can then create a new pipeline using this pipeline as base:
pipeline_b = pipeline_a.copy(new_name='Pipeline B') # pipeline_a itself is immutable pipeline_b.add_trainer(...) # change trainer step pipeline_b.run()
In the above example, if there is a shared Metadata and Artifact Store, all steps preceding the TrainerStep in the pipeline will be cached and re-used in Pipeline B. This way the entire team is benefiting from each other’s work implicitly, and can see each other’s results and progress as it evolves.
How to set it up¶
For a concrete example on how to set up collaboration completely, check out our tutorial using Google Cloud Platform. Using any other cloud provider is also possible, as the only requirement is the Metadata Store and Artifact Store exist in a globally accessible place. Also, not using a cloud provider at all is also possible, but would entail losing the advantages of a shared metadata + artifact store (see above note.)
