‘Steppy’ is a light python-3 library that can be used for fast and reproducible data science/machine learning experimentation. It reduces the burden of data scientists from software development issues. The minimal interface does not impose constraints for ‘Steppy’; instead, it enables clean machine learning pipeline design.
‘Steppy’ solves some of the data science project problems with the help of minimal interface for building machine learning pipelines. It uses two simple abstractions: Step and Tranformer
Step: It is the execution wrapper over the transformer. Example: Checking intermediate results.
Tranformer: It represents the computation step and performs operation on data. Mostly, Transformers are neural networks, machine learning algorithms..
Installation
Steppy requires python3.5 or above.
pip3 install steppyGetting started with steps (Code Source: https://github.com/neptune-ml/steppy-examples/blob/master/tutorials/1-getting-started.ipynb)
This notebook shows how to create steps, fit them to data, transform new data and take advantage of persistence
