Thanks to Graham's help, I found the typo ("sys.path.append(os.getcwd)" should have been "sys.path.append(os.getcwd())"), and all is well. W On 4/2/06, Graham Dumpleton <grahamd@dscpl.com.au> wrote:

This may be un-reproducible, and it does NOT happen within ipython shell, but I am getting the backtrace below when trying to import scipy within my application. I would guess it has to do with the very outdated ebuild of mod_python, (see the gentoo bug: http://bugs.gentoo.org/show_bug.cgi?id=123852), but just in case anybody has any quick fixes, please let me know.

I have restarted Apache numerous times to make sure there isn't some weird cache thing going on (the source of most of my phantom bug reports). Scipy 0.3.2 does not have this problem.

Looking through pkg_resources.py, critical bit of code seems to be:

class WorkingSet(object): """A collection of active distributions on sys.path (or a similar list)"""

def __init__(self, entries=None): """Create working set from list of path entries (default=sys.path)""" self.entries = [] self.entry_keys = {} self.by_key = {} self.callbacks = []

if entries is None: entries = sys.path

for entry in entries: self.add_entry(entry)

Specifically, "entries" is set to 'sys.path' and then each entry in that is processed. The final error suggests that one of the entries in 'sys.path' is actually a function and not a string.

Are you setting 'sys.path' using PythonPath directive in mod_python and somehow stuffed it up, or are you setting 'sys.path' explicitly in any other places?

Backtrace follows. (6), with LcUtil.py, is where it tries to import and errors out.
