Problem with tracmetrix upgrading 0.11 to 0.12

I've got the same problem. Did you find an answer/workaround for this?

any solution? thanks

Try this, it works for me.

mkdir /var/www/.matplotlib chown apache.apache /var/www/.matplotlib

Replying to anonymous:

Try this, it works for me. mkdir /var/www/.matplotlib chown apache.apache /var/www/.matplotlib

Any update? I have the same problem as the original reporter.

I reported the same problem on 10/28/10.

With further investigation I have found a code fix and a work-around for this problem. I noticed on my install that I was getting errors like the following:

RuntimeError: could not create GdkCursor object)

Investigating into matplotlib I found a suggestion that this error is related to running a matplotlib backend that depends on X11 and GDK running. This problem can be fixed in the code for tracmetrix by explicitly setting the matplotlib backend to the "Agg" backend. This change should probably be made in the tracmetrix codebase.

To immediately solve my problem without changing the tracmetrix code I found that I could use the matplotlibrc file stored in PYTHON_SITE_PACKAGES/matplotlib/mpl-data to set the default matplotlib backend on my system. My server runs headless so defaulting to a non-GUI backend works for my use cases.

It doesn't look like any of these things help.

Looking into the file it has a problem with:

    configdir = os.environ.get('MPLCONFIGDIR')
    if configdir is not None:
        if not _is_writable_dir(configdir):
            raise RuntimeError('Could not write to MPLCONFIGDIR="%s"'%configdir)
        return configdir

    h = get_home()
    p = os.path.join(get_home(), '.matplotlib')

    if os.path.exists(p):
        if not _is_writable_dir(p):
            raise RuntimeError("'%s' is not a writable dir; you must set %s/.matplotlib to be a writable dir.  You can also set environment variable MPLCONFIGDIR to any writable directory where you want matplotlib data stored "% (h, h))
    else:
        if not _is_writable_dir(h):
            raise RuntimeError("Failed to create %s/.matplotlib; consider setting MPLCONFIGDIR to a writable directory for matplotlib configuration data"%h)

        os.mkdir(p)

    return p

It seems that it is running but not picking up things from the environment -

When I open up python and run:

>>> os.environ.get('MPLCONFIGDIR')
'/var/lib/matlab'

But the error I get is "Failed to create /root/.matplotlib;"

 Failed to create /root/.matplotlib; 

So it has skipped over that bit of code because it doesn't reckon that it has any permissions to that directory. However if I actually look at those permissions:

# ls /var/lib/matlab/ -la
total 36
drwxrwxrwx  4 apache apache  4096 Nov  3 09:15 .
drwxr-xr-x 24 root   root    4096 Sep 23 17:11 ..
drwxrwxrwx  2 apache apache  4096 Nov  3 09:15 .matplotlib
-rwxrwxrwx  1 apache apache 19611 Sep 24 10:16 fontList.cache
drwxrwxrwx  2 apache apache  4096 Sep 24 10:16 tex.cache

How does that make any sense?

---

So I fixed it just by hard coding the configdir = /var/lib/matlab and it seems to work now. It seems like it isn't picking up my environment variables.

I've Trac 0.12.1 running on Ubuntu 10.04.

The environment variable probably needs to be set in the trac CGI script or similar, like this:

# mkdir /var/cache/apache2/matplotlib
# chown www-data: /var/cache/apache2/matplotlib

Finally the tracmetrix plugin loaded and the pdashboard can be selected, but still no graphic is visible.

Using YUI 2.8.2r1 (locally installed to avoid problems/warnings with the https server), I needed to add the inclusion of swf-min.js; same for pdashboard.html

#4845 may help with the issues encountered here.

Could someone that was experiencing these problems try again with the latest 0.12 branch and see if the issue has been fixed? I have some reason to believe it may have been.

I was spinning my wheels and this comment was my solution, changing my backend to Agg.
