Troubleshooting
===============
.. _matplotlib-version:
Obtaining Matplotlib version
----------------------------
To find out your Matplotlib version number, import it and print the
``__version__`` attribute::
>>> import matplotlib
>>> matplotlib.__version__
'0.98.0'
.. _locating-matplotlib-install:
:file:`matplotlib` install location
-----------------------------------
You can find what directory Matplotlib is installed in by importing it
and printing the ``__file__`` attribute::
>>> import matplotlib
>>> matplotlib.__file__
'/home/jdhunter/dev/lib64/python2.5/site-packages/matplotlib/__init__.pyc'
.. _locating-matplotlib-config-dir:
:file:`matplotlib` configuration and cache directory locations
--------------------------------------------------------------
Each user has a Matplotlib configuration directory which may contain a
:ref:`matplotlibrc <customizing-with-matplotlibrc-files>` file. To
locate your :file:`matplotlib/` configuration directory, use
:func:`matplotlib.get_configdir`::
>>> import matplotlib as mpl
>>> mpl.get_configdir()
'/home/darren/.config/matplotlib'
On Unix-like systems, this directory is generally located in your
:envvar:`HOME` directory under the :file:`.config/` directory.
In addition, users have a cache directory. On Unix-like systems, this is
separate from the configuration directory by default. To locate your
:file:`.cache/` directory, use :func:`matplotlib.get_cachedir`::
>>> import matplotlib as mpl
>>> mpl.get_cachedir()
'/home/darren/.cache/matplotlib'
On Windows, both the config directory and the cache directory are
the same and are in your :file:`Documents and Settings` or :file:`Users`
directory by default::
>>> import matplotlib as mpl
>>> mpl.get_configdir()
'C:\\Documents and Settings\\jdhunter\\.matplotlib'
>>> mpl.get_cachedir()
'C:\\Documents and Settings\\jdhunter\\.matplotlib'
If you would like to use a different configuration directory, you can
do so by specifying the location in your :envvar:`MPLCONFIGDIR`
environment variable -- see
:ref:`setting-linux-macos-environment-variables`. Note that
:envvar:`MPLCONFIGDIR` sets the location of both the configuration
directory and the cache directory.
