I have tested the trick on a file which has 2.7 10**9 nodes, ie > 2**31
and I get the following message:

File "/usr/local/lib/python2.5/site-packages/numpy/core/memmap.py", line 
193, in __new__
      mm = mmap.mmap(fid.fileno(), bytes, access=acc)
      ValueError: mmap length is greater than file size

Is there a workaround to consider long integer (if this is the issue) ?

TIA.


Cheers,
