[Matplotlib-users] Floating exception when rendering ylabel()
I just installed matplotlib 0.87.5 and numpy 1.0 from source on my Debian sarge (stable release) system. (I chose those versions because they're the ones currently included in the testing etch release.) Everything I've tried has worked *except* the ylabel() command. Whenever a plot containing a ylabel is rendered (on the screen with show() or figure(), or non-interactively with savefig()), python exits with the error Floating exception This does not happen if the ylabel() command is omitted, and there is no problem with xlabel(), so I assume the issue is rotating the text for the y axis label. Simple example: == ipython -pylab /usr/lib/python2.3/site-packages/numpy/ctypeslib.py:12: UserWarning: All features of ctypes interface may not work with ctypes 1.0.1 warnings.warn(All features of ctypes interface may not work with \ /usr/lib/python2.3/site-packages/IPython/Shell.py:628: GtkDeprecationWarning: gtk.timeout_add is deprecated, use gobject.timeout_add instead self.gtk.timeout_add(self.TIMEOUT, self.on_timer) Python 2.3.5 (#2, Oct 16 2006, 19:19:48) Type copyright, credits or license for more information.
