Re: [Pytables-users] Problem with PyTables 1.3.3 and numpy

[Francesc A. <fa...@ca...>]

Hi Berthold,

numarray 1.5.2 have problems when running against Python 2.5 and
64-bit platforms (see [1]). As PyTables 1.x does use numarray at its
core, it will inherits the same problems.

Are you using a 64-bit platform? If this is the case, my advice is
that you keep using python 2.4 until the numarray crew would support
the above configuration (or until PyTables 2.0, with NumPy at its
core, hits the market).
