LArray is open source Python library that aims to provide tools for easy exploration and manipulation of N-dimensional labelled data structures.
- N-dimensional labelled array objects to store and manipulate multi-dimensional data
- I/O functions for reading and writing arrays in different formats: CSV, Microsoft Excel, HDF5, pickle
- Arrays can be grouped into Session objects and loaded/dumped at once
- User interface with an IPython console for rapid exploration of data
- Compatible with the pandas library: Array objects can be converted into pandas DataFrame and vice versa.
The easiest route to installing larray is through Conda. For all platforms installing larray can be done with:
conda install -c larray-project larray
This will install a lightweight version of larray depending only on Numpy and Pandas libraries only. Additional libraries are required to use the included graphical user interface, make plots or use special I/O functions for easy dump/load from Excel or HDF files. Optional dependencies are described below.
Installing larray with all optional dependencies can be done with
conda install -c larray-project larrayenv
You can also first add the channel larray-project to your channel list
conda config --add channels larray-project
and then install larray (or larrayenv) as
conda install larray
The latest release of LArray is available from https://github.com/larray-project/larray.git
Once you have satisfied the requirements detailed below, simply run:
python setup.py install
- pytables: for working with files in HDF5 format.
- xlwings: recommended package to get benefit of all Excel features of LArray. Only available on Windows and Mac platforms.
- openpyxl: recommended package for reading and writing Excel 2010 files (ie: .xlsx)
- xlsxwriter: alternative package for writing data, formatting information and, in particular, charts in the Excel 2010 format (ie: .xlsx)
- xlrd: for reading data and formatting information from older Excel files (ie: .xls)
- xlwt:
- for writing data and formatting information to older Excel files (ie: .xls)
- larray_eurostat: provides functions to easily download EUROSTAT files as larray objects. Currently limited to TSV files.
LArray includes a graphical user interface to view, edit and compare arrays.
- pyqt (4 or 5): required by larray-editor (see below).
- pyside: alternative to PyQt.
- qtpy: required by larray-editor. Provides support for PyQt5, PyQt4 and PySide using the PyQt5 layout.
- larray-editor:
required to use the graphical user interface associated with larray.
It assumes that qtpy and pyqt or pyside are installed.
On windows, creates also a menu
