[Pytables-users] writing numarray record arrays to pytables

[Gerry W. <ge...@uc...>]

When I run the attached example, I get the output below. What's going 
wrong in test2()? How can I output the numarray record array containing 
character data in test2()?

Thanks,

Gerry Wiener



Pytables version:  1.1
test1 record array:  RecArray[
(20.0, 1),
(3.5, 2)
]
<class 'numarray.numarraycore.NumArray'>
test1 succeeded
test2 record array:  RecArray[
(20.0, 'ab'),
(3.5, 'cd')
]
<class 'numarray.strings.CharArray'>
