I was trying to look up a module, and, after installing matplotlib 0.98.1, I get:

modules

Please wait a moment while I gather a list of all available modules...

This looks like you have the experimental "traited config" turned on,
and Michael may have not cleaned autolayout from the tconfig defaults
when he removed it. Did you build from source or get your package
from elsewhere. If building from source, edit setup.cfg next to
setup.py and make sure that the traited config is off

  ## Experimental config package support, this should only be enabled by
  ## matplotlib developers, for matplotlib development
  enthought.traits = False
  configobj = False

If you got it from elsewhere, let the packager know this should be
turned off. And Darren, can you make sure that tconfig is updated
vis-a-vis the autolayout param removal.

I removed the autolayout key from all the various config files in SVN, but of course, forgot that any users with already-installed copies of matplotlibrc will get this error. Should I put the key back in as a deprecated no-op?

Cheers,
Mike

Yes, that is probably a good idea. Issue a warning pointing them to
the latest rc (http://matplotlib.sf.net/matplotlibrc).

I built from source. I removed my existing installation of matplotlib, but I am still getting the same error. I had not been using setup.cfg, but edited the template so that the experimental packages were turned off. I am still getting this error.

Check to see if you have a matplotlibrc file in ~/.matplotlib. If so,
replace it with the latest one from site-packages/matplotlib/mpl-data
(or comment out the autolayout line in the one you already have in
~/.matplotlib).

Let us know if this works.

my .matplotlib folder is empty. also, my installation otherwise appears to work.

### MATPLOTLIBRC FORMAT

# This is a sample matplotlib configuration file - you can find a copy
# of it on your system in
# site-packages/matplotlib/mpl-data/matplotlibrc. If you edit it
# there, please note that it will be overridden in your next install.
# If you want to keep a permanent local bopy that will not be
# over-written, place it in HOME/.matplotlib/matplotlibrc (unix/linux
# like systems) and C:\Documents and Settings\yourname\.matplotlib
# (win32 systems).

···

#
# This file is best viewed in a editor which supports python mode
# syntax highlighting # Blank lines, or lines starting with a comment
# symbol, are ignored, as are trailing comments. Other lines must
# have the format # key : val # optional comment # Colors: for the
# color values below, you can either use - a matplotlib color string,
# such as r, k, or b - an rgb tuple, such as (1.0, 0.5, 0.0) - a hex
# string, such as ff00ff or #ff00ff - a scalar grayscale intensity
# such as 0.75 - a legal html color name, eg red, blue, darkslategray

#### CONFIGURATION BEGINS HERE
# the default backend; one of GTK GTKAgg GTKCairo CocoaAgg FltkAgg
# QtAgg Qt4Agg TkAgg WX WXAgg Agg Cairo GDK PS PDF SVG Template
backend : GTKAgg
numerix : numpy # numpy, Numeric or numarray
#maskedarray : False # True to use external maskedarray module
                            # instead of numpy.ma; this is a temporary
                            # setting for testing maskedarray.
#interactive : False # see http://matplotlib.sourceforge.net/interactive.html
#toolbar : toolbar2 # None | classic | toolbar2
#timezone : UTC # a pytz timezone string, eg US/Central or Europe/Paris

# Where your matplotlib data lives if you installed to a non-default
# location. This is where the matplotlib fonts, bitmaps, etc reside
#datapath : /home/jdhunter/mpldata

### LINES
# See http://matplotlib.sourceforge.net/matplotlib.lines.html for more
# information on line properties.
#lines.linewidth : 1.0 # line width in points
#lines.linestyle : - # solid line
#lines.color : blue
#lines.marker : None # the default marker
#lines.markeredgewidth : 0.5 # the line width around the marker symbol
#lines.markersize : 6 # markersize, in points
#lines.dash_joinstyle : miter # miter|round|bevel
#lines.dash_capstyle : butt # butt|round|projecting
#lines.solid_joinstyle : miter # miter|round|bevel
#lines.solid_capstyle : projecting # butt|round|projecting
#lines.antialiased : True # render lines in antialised (no jaggies)

### PATCHES
# Patches are graphical objects that fill 2D space, like polygons or
# circles. See
# http://matplotlib.sourceforge.net/matplotlib.patches.html for more
# information on patch properties
#patch.linewidth : 1.0 # edge width in points
#patch.facecolor : blue
#patch.edgecolor : black
#patch.antialiased : True # render patches in antialised (no jaggies)

### FONT
#
# font properties used by text.Text. See
# http://matplotlib.sourceforge.net/matplotlib.font_manager.html for more
# information on font properties. The 6 font properties used for font
# matching are given below with their default values.
#
# The font.family property has five values: 'serif' (e.g. Times),
# 'sans-serif' (e.g. Helvetica), 'cursive' (e.g. Zapf-Chancery),
# 'fantasy' (e.g. Western), and 'monospace' (e.g. Courier). Each of
# these font families has a default list of font names in decreasing
# order of priority associated with them.
#
# The font.style property has three values: normal (or roman), italic
# or oblique. The oblique style will be used for italic, if it is not
# present.
#
# The font.variant property has two values: normal or small-caps. For
# TrueType fonts, which are scalable fonts, small-caps is equivalent
# to using a font size of 'smaller', or about 83% of the current font
# size.
#
# The font.weight property has effectively 13 values: normal, bold,
# bolder, lighter, 100, 200, 300, ..., 900. Normal is the same as
# 400, and bold is 700. bolder and lighter are relative values with
# respect to the current weight.
#
# The font.stretch property has 11 values: ultra-condensed,
# extra-condensed, condensed, semi-condensed, normal, semi-expanded,
# expanded, extra-expanded, ultra-expanded, wider, and narrower. This
# property is not currently implemented.
#
# The font.size property is the default font size for text, given in pts.
# 12pt is the standard value.
#
#font.family : sans-serif
#font.style : normal
#font.variant : normal
#font.weight : medium
#font.stretch : normal
# note that font.size controls default text sizes. To configure
# special text sizes tick labels, axes, labels, title, etc, see the rc
# settings for axes and ticks. Special text sizes can be defined
# relative to font.size, using the following values: xx-small, x-small,
# small, medium, large, x-large, xx-large, larger, or smaller
#font.size : 12.0
#font.serif : Bitstream Vera Serif, New Century Schoolbook, Century Schoolbook L, Utopia, ITC Bookman, Bookman, Nimbus Roman No9 L, Times New Roman, Times, Palatino, Charter, serif
#font.sans-serif : Bitstream Vera Sans, Lucida Grande, Verdana, Geneva, Lucid, Arial, Helvetica, Avant Garde, sans-serif
#font.cursive : Apple Chancery, Textile, Zapf Chancery, Sand, cursive
#font.fantasy : Comic Sans MS, Chicago, Charcoal, Impact, Western, fantasy
#font.monospace : Bitstream Vera Sans Mono, Andale Mono, Nimbus Mono L, Courier New, Courier, Fixed, Terminal, monospace
