README
idx2numpy
=========
[](https://travis-ci.org/ivanyu/idx2numpy)
`idx2numpy` package provides a tool for converting files to and 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.
Installation
============
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
Usage
=====
```python
import idx2numpy
# Reading
ndarr = idx2numpy.convert_from_file('myfile.idx')
f_read = open('myfile.idx', 'rb')
ndarr = idx2numpy.convert_from_file(f_read)
s = f_read.read()
ndarr = idx2numpy.convert_from_string(s)
# Writing
idx2numpy.convert_to_file('myfile_copy.idx', ndarr)
f_write = open('myfile_copy2.idx', 'wb')
idx2numpy.convert_to_file(f_write, ndarr)
s = convert_to_string(ndarr)
```
