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.
Are you "really" on a 64-bit system ? Is this Linux ? Is your Python the original from the distro - or did you build it yourself ? Do a: >>> import sys;print sys.maxint Did you build numpy yourself or did you download a binary ? HTH, Sebastian
