[yt-users] h5py and PyTables problem with HDF5 1.8.3

[Rick Wagner]

Hi,

This is just a word of caution if anyone finds themselves getting an  
error from h5py or PyTables about H5Zregister. Apparently something  
changed in that release (1.8.3) which trips up both of the packages.  
1.8.2 seems to be fine.

Hi Andrew,
   I wouldn't worry about the `--prefix' option just yet--seems that  
it's a
problem with HDF5 1.8.3 -- here's a quote from a guy who works on  
PyTables
(Francesc):

Mmh, I've just tried HDF5 1.8.3 and had errors too:

EHDF5-DIAG: Error detected in HDF5 (1.8.3) thread 0:

  #004: H5Z.c line 1006 in H5Z_pipeline(): required filter is not

I'm afraid that the LZO compressor is not correctly detected (they have
probably changed the way to register filters).

Hope that helps! Thanks for the quick reply.
