Before, you were probably using Numeric, and had pylab loaded.  pylab loads 
MA, the old Masked Array module, which had a side-effect of modifying the 
array printout routines to suppress large arrays.

I'm not sure where the equivalent functionality is in numpy, but I hope it's 
been changed from being a silent side effect of an obscure module import to 
something a little more explicit.
