omfpandas 0.7.0

A package for reading and writing OMF data with pandas

omfpandas

A pandas (and parquet) interface for the Open Mining Format package (omf).

When working with OMF files, it is often useful to convert the data to a pandas DataFrame. This package provides a simple interface to do so.

The parquet format is a nice, compact, efficient format to persist pandas DataFrames. This package also provides a simple interface to convert an omf element to a parquet file. When datasets do not fit into memory, parquet files can be read in chunks or by column.

Note: This package only supports omf 2.0, which is currently only a pre-release.

Installation

pip install omfpandas

If you intend to use the parquet functionality, you will need to install the optional dependencies.

pip install omfpandas[io]
