Reproducible Data Science with Pachyderm

By: Svetlana Karslioglu

Overview of this book

Pachyderm is an open source project that enables data scientists to run reproducible data pipelines and scale them to an enterprise level. This book will teach you how to implement Pachyderm to create collaborative data science workflows and reproduce your ML experiments at scale. You’ll begin your journey by exploring the importance of data reproducibility and comparing different data science platforms. Next, you’ll explore how Pachyderm fits into the picture and its significance, followed by learning how to install Pachyderm locally on your computer or a cloud platform of your choice. You’ll then discover the architectural components and Pachyderm's main pipeline principles and concepts. The book demonstrates how to use Pachyderm components to create your first data pipeline and advances to cover common operations involving data, such as uploading data to and from Pachyderm to create more complex pipelines. Based on what you've learned, you'll develop an end-to-end ML workflow, before trying out the hyperparameter tuning technique and the different supported Pachyderm language clients. Finally, you’ll learn how to use a SaaS version of Pachyderm with Pachyderm Notebooks. By the end of this book, you will learn all aspects of running your data pipelines in Pachyderm and manage them on a day-to-day basis.

Exploring output parameters

Output parameters enable you to configure what happens to your processed data after the result lands in the output repository. You can set it up to be placed in an external S3 repository or configure an egress.

s3_out

The s3_out parameter enables your Pachyderm pipeline to write output to an S3 repository instead of the standard pfs/out. This parameter requires a Boolean value. To access the output repository, you would have to use an S3 protocol address, such as s3://<output-repo>. The output repository will still be eponymous to your pipeline's name.

The following code shows how to define an s3_out parameter in YAML format:

s3_out: true

Here's how to do the same in JSON format:

"s3_out": true

Now, let's learn about egress.

egress

The egress parameter enables you to specify an external location for your output data. Pachyderm supports Amazon S3 (the s3:// protocol), Google Cloud Storage (the gs:...
