[Matplotlib-users] Interactive Applications using Matplotlib

According to the PR you reference, the fix for this was merged back in Jan 2013, so that means that this fix is in version 1.2.x and up. Are you saying that you still can't do imread(urllib.request.urlopen(url))? On Thu, Mar 19, 2015 at 8:54 PM, Ryan Nelson rnelsonc...@gmail.com wrote: Hello

Re: [Matplotlib-users] segmentation fault when saving images

The warnings probably have nothing to do with the issue at hand. Try this. Install the package faulthandler and add the appropriate lines to your Bdipoly.py script and run it again. That way, we can get a traceback and find out where it is segfaulting from.

Re: [Matplotlib-users] ImportError: No module named six

Chances are, there is some sort of mixup in your installs (as evidenced by the failure to go back to the previous version). I would try uninstalling all matplotlib installs, then checking to see if python still sees matplotlib anywhere (by running the script). It *should* say No module named

Ok, this really should be simple (and I am sure it is), but I cannot, for the life of me, find the appropriate documentation for it. We need better documentation about how to utilize the offset-text feature of tickers. It can be either a multiple offset or an additive offset. In any case, I know
