[Matplotlib-users] Math font warnings

[Markus P. <mar...@gm...>]

Hi, list.  Whenever I use matplotlib, I see the following set of
warnings:


/usr/lib64/python2.7/site-packages/matplotlib/font_manager.py:1242:
UserWarning: findfont: Font family ['cmb10'] not found. Falling back to
Bitstream Vera Sans
  (prop.get_family(), self.defaultFamily[fontext]))
/usr/lib64/python2.7/site-packages/matplotlib/font_manager.py:1252:

/usr/lib64/python2.7/site-packages/matplotlib/font_manager.py:1242:

/usr/lib64/python2.7/site-packages/matplotlib/font_manager.py:1242:

They don't seem to affect my output, but I looked into it anyway.  It
turns out that the texcm-ttf package installed by most distributions
only includes a handful of fonts (cmex10.ttf, cmmi10.ttf, cmr10ttf,
cmsy10.ttf).  I was able to get rid of the warnings by manually
installing the missing fonts from
http://tug.ctan.org/tex-archive/fonts/cm/ps-type1/bakoma/ttf/

Should distributions be installing the rest of the TeX fonts like I did?
Is there another way to avoid these warnings?  Thanks.
