Hi all,
I tried to compile scipy with Python 2.5 and Intel C++/Fortran compiler. The first import failed:
In [1]:from scipy import * ------------------------------------------------------------ File "[...]/lib/python2.5/site-packages/scipy/maxentropy/maxentropy.py", line 69 from __future__ import division <type 'exceptions.SyntaxError'>: from __future__ imports must occur at the beginning of the file
That problem was easy to fix just by following the instructions of that message in 2 files:
scipy/maxentropy/maxentropy.py scipy/maxentropy/maxentutils.py
Is that import necessary with Python 2.5 or even Python 2.4?
Yes. Integer division will not be changing in the 2.x releases.
I'm checking in a change that moves those statements up, but not before docstrings. I don't have a 2.5 interpreter to check this out with, and I can see no reference to it in the "What's New" documentation, so please let me know if it works for you.
FWIW, it's been true since 2.1, that __future__ statements have to be the first bit of code in the module (excluding docstrings); see PEP 236 (http://www.python.org/dev/peps/pep-0236/). Looks like that hasn't been enforced for < 2.5 for features that the interpreter supports (although for non-supported features, like "from __future__ import blah", all the versions I have complain). -- |>|\/|< /--------------------------------------------------------------------------\ |David M.
