Hi Stephen, There are no immediate plans to support LZO in h5py, and in fact I'm starting to regret including any fast compressor at all as I'm now responsible for maintaining it. :) The reason for the dichotomy is that LZO is released under the GPL, which is incompatible with h5py's license. The

Hi Andrew, Do you have any plans to support LZO compression in h5py? I have lots of LZO-compressed datasets created with PyTables. There's a real barrier to using both h5py and PyTables if the fast decompressor options are just LZF on h5py and LZO on PyTables. Many thanks Stephen Andrew Colle

Thanks, Ondrej. For the record, h5py is designed to provide a "NumPy-like" interface to HDF5, along with a near-complete wrapping of the low-level HDF5 C API. It has none of the database-like features of PyTables. The FAQ entry has more info. Andrew Collette On Mon, Feb 9, 2009 at 1:06 PM, Ond
