matplotlib-users Mailing List for matplotlib

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.

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

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

 elif path == '' or path.endswith('/'):

I have no home directory on my server (and probably don't have the

Thanks!

This sounds like something that can be fixed quite easily in mpl, and 
that if not fixed is likely to trip up other people. Would you turn this 
into a github issue, please? Or, a PR?
Thank you.

Figured it out. problem is xelatex was not installed. Too bad the traceback 
can't be more clear on this.

I tried this at home on my Mac. Tornado was already installed, so I
updated it to 3.2.1, and ran a Matplotlib app I have which allows me
to set the backend on the command line. I get the exact same behavior
as at work on my Linux desktop. I get a page at 127.0.0:8988 with a
"Figure 1" link. Clicking that takes me to 127.0.0.1:8988/1, which is
a blank page.
Chrome is my default web browser on both Linux and the Mac. I manually
visited the page from both Firefox and Safari, clicked the link,
and... nothing. The same behavior as on Chrome.
Then I had the bright idea to look at the JavaScript console. It shows
this error message:
 Uncaught SyntaxError: Unexpected token &
Clicking that error took me to this line:
var fig = new figure('1', websocket_url_prefix);
Are those entities supposed to be ''? What bit of code generates that
JavaScript?
