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 = 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 = state["_type"]
AttributeError: ("'str' object has no attribute 'name'", <function
ClassicUnpic\kler at 0xb7b08e9c>, (<class
'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.

Mike: My guess is I saved the data as a pickle Numeric (not numarray) object. You can either install Numeric, or I can re-pickle it for you with numarray.

Hello Jeff,
I tried loading the file etopo20.pickle by itself but got the same error:
import cPickle
a = cPickle.load(open('etopo20.pickle','rb'))
Traceback (most recent call last):
File "<stdin>", line 1, in ?
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 = state["_type"]
AttributeError: ("'str' object has no attribute 'name'", <function
ClassicUnpic\kler at 0xb71e48b4>, (<class
'numarray.numarraycore.NumArray'>, {'_type': 'Floa\t32', '_itemsize':
4, '_shape': (1081,), '_bytestride': 4, '_byteoffset': 0, '_\version':
'1.1', '_byteorder': 'big', '_data': <memory at 082ee9a0 with
size:43\24 held by object 082ee980 aliasing object 00000000>,
'_strides': (4,)}))
Looking at etopo20.pickle itself, the 4th line reads
'cnumarray.generic' - I'm guessing that means it is stored using
numarray.
Do I need a specific version of python or numarray to read it? I have
both Numeric (23.1) and numarray installed already.
Mike.

Mike: Not that I know of. I'm puzzled by this one. You said in your first message that you are using numarray 0.8 - I think that might be too old. It's up to 1.3.1 now, and I'm sure I created that pickle with at least 1.1.

Bingo! One upgrade to the latest numarray and everything works fine.
Many thanks for your help.
Mike.
