matplot crases because of XDG_CONFIG_HOME variable

Paul_Tremblay · May 7, 2014, 2:20pm

I am using matplotllib as part of web server. matplotlib causes my server to crash with this error:

File “/apollo/env/Ssdf/lib/python2.7/site-packages/matplotlib/init.py”, line 597, in _get_configdir

return _get_config_or_cache_dir(_get_xdg_config_dir())

File “/apollo/env/Ssdf/lib/python2.7/site-packages/matplotlib/init.py”, line 534, in _get_xdg_config_dir
return os.environ.get(‘XDG_CONFIG_HOME’, os.path.join(get_home(), ‘.config’))

File “/apollo/env/Ssdf/bin/…/…/…/package/local_1/Linux-2.6c2.5-x86_64/Python27/Python27-487.0-0/lib/python2.7/posixpath.py”, line 77, in join
elif path == ‘’ or path.endswith(’/’):

<type ‘exceptions.AttributeError’>: ‘NoneType’ object has no attribute ‘endswith’

I have no home directory on my server (and probably don’t have the permissions to create one). What is the correct way to fix this problem?

Thanks!

Paul

How did you install matplotlib? I’ve had success using anaconda on cheap $7/month web servers before

I am using our companies pacaking system. The version of matplotlib is 1.3.1, by the way.

I’ve discovered the problem and a fix. $HOME is set to /home/ptremblay, but /home/ptremblay does not exist. If I do:

import os
try:
import matplotlib
except AttributeError as msg:

    os.environ['HOME'] = '/apollo/env/Ssdf/var/home_config/'
    import matplotlib

Then I can import the library.

However, this really is a bug. I have spent about two hours trying to get this to work on EC.

Where to I file bugs?

Hi Paul and Paul,

I thought I'd pile onto this Paul Pile...

Here's a recent issue which may be related to yours,

github.com/matplotlib/matplotlib

Different paths for get_configdir and matplotlib_fname()

opened 07:13PM - 14 May 14 UTC

closed 06:52PM - 01 Jun 19 UTC

amelio-vazquez-reina

Documentation Difficulty: Easy

I work in a Linux system that uses a rather unconventional `HOME` directory. How…ever, the `HOME` environment is always set up properly. ``` > echo $HOME > /opt/my_home_directory/ ``` I have set up the init files for `matplotlib` properly under: `$HOME/matplotlib/matplotlibrc` and also, just in case under: `$HOME/.matplotlib/matplotlibrc` However, when I ask matplotlib, it looks confused: ``` > matplotlib.get_configdir() '/opt/my_home_directory/.matplotlib` >matplotlib.matplotlib_fname() '/some/long/path/anaconda/envs/py27/lib/python2.7/site-packages/matplotlib/mpl-data/matplotlibrc ``` The second one is wrong. I want to use `matplotlibrc` under my `$HOME` directory. Why does `matplotlib` return two different paths, and how can I make it use the one I want?

but if that doesn't capture the problem you are seeing, and you
don't find an issue open for the behavior you're seeing, please
open a new one.

best,

···

Thanks. New issue submitted.

In my humble opinion, the creation of a home configuration directory should be optional, only implemented by an option from the command line. Otherwise, a small detail like creating a directory can cause major headaches.
