Project description

SnowPy

Current release: SnowPy [v0.1.3]

SnowPy - A Python library to serve machine learning projects as a data gateway

'SnowPy' is a Python library providing a set of user-friendly functions to help upload and download data from different sources including database systems such as Microsoft SQL Server, Snowflake, (more to come), Email servers, data files, images and sound files. Functions of the 'SnowPy' was intially realsed as data tools for the MLToolKit Project (https://mltoolkit.github.io/MLToolKit). Thus, 'SnowPy' shares functions with 'PyMLToolKit' and 'TextLab' being developed under the MLToolKit Project.
