HDF5 for Python (h5py) is a general-purpose Python interface to the Hierarchical Data Format library, version 5. HDF5 is a mature scientific software library originally developed at NCSA, designed for the fast, flexible storage of enormous amounts of data. >From a Python programmer's perspective, HDF5 provides a robust way to store data, organized by name in a tree-like fashion. You can create datasets (arrays on disk) hundreds of gigabytes in size, and perform random-access I/O on desired sections. Datasets are organized in a filesystem-like hierarchy using containers called "groups", and accessed using the traditional POSIX /path/to/resource syntax. The beta will be available for 1-2 weeks. Because of the substantial number of changes in this release, we encourage all current and prospective h5py users to try out the beta and provide feedback, either to the mailing list (h5py at googlegroups) or on the bug tracker as appropriate. * What's new: http://h5py.alfven.org/docs-1.4/intro/whatsnew.html * Google code site: http://h5py.googlecode.com Most exciting changes --------------------- * Significant improvements in stability, from a refactoring of the low-level component which talks to HDF5. * HDF5 1.8.3 through 1.8.7 now work correctly and are officially supported. * Python 3.2 is officially supported by h5py! Thanks especially to Darren Dale for getting this working. * HDF5 1.6.X is no longer supported on any platform; following the release of 1.6.10 some time ago, this branch is no longer maintained by The HDF Group. * Python 2.6 or later is now required to run h5py. This is a consequence of the numerous changes made to h5py for Python 3 compatibility.
