Problem with matplotlib Basemap in Spyder

[Leopoldo Pena]

Hi folks,

I am trying to get familiar with the Basemap library. Just trying some of the examples in the website I run into some problems under Spyder. If I run the same script on an separate Ipython shell or Notebook I have no problems at all. Running this script under Spyder 2.2-rc:

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.)

m.bluemarble()

plt.show()

I get the following error message:
Traceback (most recent call last):

Any hint of what is going on here?

Thanks

Hi Leopoldo,

You are right, this is a bug in our side. I filled an issue for it and it'll be fixed in 2.2.1.

Thanks for your interest in Spyder,
Carlos
