Whenever I run a python with basemap I get a segmentation fault error. For
example when running:
from mpl_toolkits.basemap import Basemap
import matplotlib.pyplot as plt
# setup Lambert Conformal basemap.
# set resolution=None to skip processing of boundary datasets.
m = Basemap(width=12000000,height=9000000,projection='lcc',
resolution=None,lat_1=45.,lat_2=55,lat_0=50,lon_0=-107.)
# draw a land-sea mask for a map background.
# lakes=True means plot inland lakes with ocean color.
m.drawlsmask(land_color='coral',ocean_color='aqua',lakes=True)
plt.show()
I get a segmentation fault core dump error.
I have done some reading online about this and they say that it could be
because I accidently installed two versions of geos (
http://trac.osgeo.org/geos/), which include geos.3.3.6 and geos.3.3.3 which
was already available in the basemap package. Could this be the problem
that is creating the segmentation fault core dump? If so how do I
uninstall the geos libraries that I do not need. There is not a lot of
specific information on how to uninstall geos libraries and I really need a
specific guide on how to do this and get the above script working properly.

Could you use the faulthandler package to help produce a stack trace?
https://pypi.python.org/pypi/faulthandler/
If you are using python 3.4 or greater, it should already be in the
standard library.
Cheers!
