Project description
idx2numpy
idx2numpy package provides a tool for converting files from IDX format to numpy.ndarray. You can meet files in IDX format, e.g. when you’re going to read the [MNIST database of handwritten digits] (http://yann.lecun.com/exdb/mnist/) provided by Yann LeCun.
The description of IDX format also can be found on this page.

The easiest way to install is by using pip to pull it from PyPI:
pip install idx2numpy
You can also clone the Git repository from Github and install the package manually:
git clone https://github.com/ivanyu/idx2numpy.git python setup.py install
Note: Unfortunately, work with Python 3 hasn’t been tested yet.
Usage
import idx2numpy ndarr = idx2numpy.convert_from_file(‘myfile.idx’)
f = open(‘myfile.idx’, ‘rb) ndarr = idx2numpy.convert_from_file(f)
