What are you running? Are you really using NumPy or are you using Numeric?
In : a = rand(21000)
In : a
array([ 0.72911787, 0.41493949, 0.88521075, ..., 0.3816934 ,
NumPy has a limit in the number of elements that are printed. The
default is 1000 I think. It can be changed using set_printoptions.
The code is adapted from NumArray so thank Perry Greenfield and friends
for this very nice feature :-)
