[Matplotlib-users] Cannot run basemap examples

[Mike E. <mik...@gm...>]

I'm having trouble running some of the examples that come with basemap
- any th\at use the file etopo20.pickle fail with an error similar to:

Traceback (most recent call last):
  File "test.py", line 12, in ?
    topodict =3D cPickle.load(open('etopo20.pickle','rb'))
  File "/usr/lib/python2.3/site-packages/numarray/generic.py", line
159, in Cla\ssicUnpickler
    self.__setstate__(state)
  File "/usr/lib/python2.3/site-packages/numarray/numarraycore.py",
line 463, i\n __setstate__
    self._type      =3D state["_type"]
AttributeError: ("'str' object has no attribute 'name'", <function

'numarray.numarraycore.NumArray'>, {'_type': 'Floa\t32', '_itemsize':
4, '_shape': (1081,), '_bytestride': 4, '_byteoffset': 0, '_\version':

size:43\24 held by object 082f8778 aliasing object 00000000>,
'_strides': (4,)}))

Can anyone tell me how to fix this?
I'm using python 2.3.4, matplotlib 0.80, basemap 0.3.2, proj 4.4.8 and
have the Python libraries numeric 23.1 and numarray 0.8 installed.

Thanks in advance,
Mike.
