Memory error only in Spyder IDE

问题

doing the following causes a MemoryError in my Spyder Python IDE:

>>> from numpy  import *
>>> a_flt = ones((7000,7000), dtype=float64)+4
>>> b_flt = ones((7000,7000), dtype=float64)+1
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>    
MemoryError
>>> 

THis is weird, since the memory usage in the statusbar of Spyder shows that only approx. 25% of my memory is used. Furthermore, when generating even a higher number of these large 7000*7000 arrays in the standard Python IDE GUI, everything works fine.

>>> from numpy  import *
>>> a_flt = ones((7000,7000), dtype=float64)+4
>>> b_flt = ones((7000,7000), dtype=float64)+1
>>> c_flt = ones((7000,7000), dtype=float64)+1
>>> d_flt = ones((7000,7000), dtype=float64)+1
>>> e_flt = ones((7000,7000), dtype=float64)+1 

Even with 5 floating point arrays created, memory requirements only amount to about a third of my total memory of 16GB. So this cannot be a real memory problem, then. I found a similiar question on this issue in a spyder google group https://groups.google.com/forum/#!msg/spyderlib/qE9tiriT91s/0x3s2Aw-efMJ, however no answer was provided. It would really be nice if someone could help me with this paradoxical situation. Thanks in advance,
Patrick

Install 64bit version of Python and Spyder. This eliminated me this error.
