[ python memory error when loading MNIST.pkl.gz ]

I am new to Python and I have downloaded the code DBN.py but there is a problem:when I was trying to load the dataset MNIST.pkl.gz.there is always an meomory error.. my code is very simple:

import cPickle, gzip, numpy
# Load the dataset
f = gzip.open('C:\Users\MAC\Desktop\mnist.pkl.gz', 'rb')
train_set, valid_set, test_set = cPickle.load(f)
f.close()

and the error is as follows:

Traceback (most recent call last):

MemoryError

I really have no idea,is it because the memory of my computer is too small? it is on windows 7,32 bits

I suspect the problem to be Spyder in this case.
As to why, I have no idea but either the process isn't allowed to allocate enugh memory outside of it's own script or it simply gets stuck in a loop some how.

Try running your code without Spyder by pasting your code into myscript.py for instance and open a terminal and navigate to the folder where you saved your script and run python myscript.py and see if that works or gives the same output.

This is based on a conversation in the comments above.
