Re: [Pytables-users] Problems with chunked datasets

[Antonio V. <val...@co...>]

Ok, I sent data you asked for yesterday.
I run some more tests:

Python 2.3.4
[GCC 3.4.2 20041017 (Red Hat 3.4.2-6.fc3)] on linux2
numarray v. 1.1.1
tables v. 0.9.1
hdf5   v. 1.6.2

and=20

Python 2.4
Win XP SP2
numarray v. 1.1.1
tables v. 0.9.1
hdf5   v. 1.6.3-pathc

the result is always the same.

bye
