Hello,
Using 0.87.4, I'm getting this traceback with a date plot:
/usr/local/stow/matplotlib0.87.4/lib/python2.4/sitepackages/matplotlib/dates.py in _from_ordinalf(x, tz)
154 dt = datetime.datetime.fromordinal(ix)
155 remainder = x  ix
> 156 hour, remainder = divmod(24*remainder, 1)
157 minute, remainder = divmod(60*remainder, 1)
158 second, remainder = divmod(60*remainder, 1)
ValueError: need more than 0 values to unpack
> /usr/local/stow/matplotlib0.87.4/lib/python2.4/sitepackages/matplotlib/dates.py(156)_from_ordinalf()
155 remainder = x  ix
> 156 hour, remainder = divmod(24*remainder, 1)
157 minute, remainder = divmod(60*remainder, 1)
And sure enough,
ipdb> divmod(0.0,1)
(0.0, 0.0)
ipdb> divmod( 24*remainder, 1 )
()
It looks like divmod is getting overloaded (?) or something in
CXX/cxx_extensions.cxx with [perhaps] this code:
Py::Object PythonExtensionBase::number_divmod( const Py::Object & )
{ missing_method( number_divmod ); return Py::Nothing(); }
which would make sense, but I haven't explored it that thoroughly. I
think what's happening is that I've got a numpy array scalar that is
sneaking in there somewhere.
For now, I'll just use the hackfix of casting remainder to a float.
Thanks,
Glen
