[SciPy-dev] misprint & system_info.py problem

[Arnd Baecker]

Hi,

I just checked out the CVS version (scipy.__version__, '0.2.1_253.3734' )
and found two small issues

a) >>> help("scipy.xplt")
 File
"/opt/python/lib/python2.3/site-packages/scipy/optimize/optimize.py", line
268
    if (c<=0) or (i%3)==2):
                         ^
SyntaxError: invalid syntax

Removing the additional bracket fixes the problem.

b)  python scipy_core/scipy_distutils/system_info.py
   gives the following error (shortened, full output at the end):

   This happens before doing a scipy installation, i.e.
   if there are no scipy* in site-packages.
   After the installation `python
      scipy_core/scipy_distutils/system_info.py`
   works fine. This may have been like this for quite a while
   as normally I don't remove the scipy* directories in site-packages.

Many thanks,

Arnd
