Websites

• Main website: http://www.h5py.org
• Source code: http://github.com/h5py/h5py
• Mailing list: h5py at googlegroups

Prerequisites

You need, at a minimum:

• HDF5 1.8.3 or later on Linux (On Windows, h5py ships with HDF5)
• Python 2.6, 2.7 or 3.2
• Any modern version of NumPy

Optionally:

• Cython 0.13 or later, to build from a git checkout
• If using Python 2.6, unittest2 is needed to run the tests

Installing from tarball

Run the following commands:

python setup.py build [--hdf5=/path/to/hdf5]
python setup.py test   # optional
[sudo] python setup.py install

Installing via easy_install

Run the following commands:

export HDF5_DIR=/path/to/hdf5   # optional
[sudo] easy_install h5py

Building from a Git checkout (UNIX)

We have switched development to GitHub. Here's how to build h5py from source:

1. Clone the project:

   git clone https://github.com/h5py/h5py.git
   

2. Generate the Cython files which talk to HDF5:

   cd h5py/h5py
   python api_gen.py
   

3. Build the project (this step also auto-compiles the .c files):

   cd ..
   python setup.py build [--hdf5=/path/to/hdf5]
   

4. Run the unit tests (optional):

   python setup.py test
