Pandas ML Utils
Pandas Machine Learning Utilities is part of a bigger set of libraries for a convenient experience. Usually exploring
statistical models start with a pandas DataFrame.
But soon enough you will find yourself converting your data frames to numpy, splitting arrays, applying min
max scalers, lagging and concatenating columns etc. As a result your notebook looks messy and became and
unreadable beast. Yet the mess becomes only worse once you start to deploy your research into a productive
application. The untested hard coded data pipelines need be be maintained at two places.
The aim of this library is to conveniently operate with data frames without and abstract away the ugly unreproducible
data pipelines. The only thing you need is the original unprocessed data frame where you started.
The data pipeline becomes a part of your model and gets saved that way. Going into production is as easy as
this:
import pandas as pd
import pandas_ml_utils # monkey patch the `DataFrame`
from pandas_ml_utils import Model
# alternatively as a one liner `from pandas_ml_utils import pd, Model`
model = Model.load('your_saved.model')
df = pd.read_csv('your_raw_data.csv')
df_prediction = df.model.predict(model)
# do something with your prediction
df_prediction.plot()
is intended to help you through your journey of statistical or machine learning models,
while you never need to leave the world of pandas.
Installation
The basic implementation supports scikit learn classifiers and regressors.
pip install pandas-ml-utils
Additional machine learning libraries are available as an add on:
pip install pandas-ml-utils-torch # pytorch implementation
pip install pandas-ml-utils-keras # keras + tensorflow 1.x implementation
Note that the keras/tensorflow version is currently stalled as I focus on pytorch recently. This might change
with PyMC4 and tensorflow probability
Example
You will find some demo projects in the examples directory. But It might also be worth it to check
the unit tests and the integration tests. Here is how classification challenge
might look like:
