Re: [Numpy-discussion] problem with numpy.. sometimes using numarray? and selection question

[<hu...@ya...>]

Just a guess, you're reading some fits file with pyfits but you didn't decl=
are=20
the variable NUMERIX for numpy (with the beta version of pyfits) or you=20
script are calling another script who are using numarray. I had both proble=
m=20
last week. Pyfits with a mix of numarray/numpy and a script to read some da=
ta=20
and return it like an array.
