The easiest fix I have found for this problem is to change the backend from "MacOS" to "TkAgg". This can be done in each file or interactive session, but that is a bit cumbersome. It's also possible to change this in the matplotlibrc file:

~|⇒ cat  ~/.matplotlib/matplotlibrc
backend: TkAgg

• http://stackoverflow.com/questions/24693360/git-large-pack-file-delete-and-rewrite

First, create list of all files tracked in the repository

git rev-list --objects --all | sort -k 2 > allfileshas.txt

Get the SHA for all committed files and sort them from biggest to smallest
