Hello All
Thanks a lot Eric. I think I have some module missing but I
cannot figure out what it is. I get the following. Any idea. This
started hapening after I reinstalled matplotlib.
File "/Users/Kennel/Pythoncodes/coolingmodel.py", line 6, in <module>
import matplotlib
File "/Library/Frameworks/Python.framework/Versions/2.5/lib/
python2.5/site-packages/matplotlib/__init__.py", line 129, in <module>
from rcsetup import defaultParams, validate_backend,
validate_toolbar
File "/Library/Frameworks/Python.framework/Versions/2.5/lib/
python2.5/site-packages/matplotlib/rcsetup.py", line 19, in <module>
from matplotlib.colors import is_color_like
File "/Library/Frameworks/Python.framework/Versions/2.5/lib/
python2.5/site-packages/matplotlib/colors.py", line 54, in <module>
import matplotlib.cbook as cbook
File "/Library/Frameworks/Python.framework/Versions/2.5/lib/
python2.5/site-packages/matplotlib/cbook.py", line 10, in <module>
import numpy.ma as ma
File "/Library/Frameworks/Python.framework/Versions/2.5/lib/
python2.5/site-packages/numpy/ma/__init__.py", line 47, in <module>
import extras
File "/Library/Frameworks/Python.framework/Versions/2.5/lib/
python2.5/site-packages/numpy/ma/extras.py", line 45, in <module>
from numpy.lib.index_tricks import AxisConcatenator
ImportError: cannot import name AxisConcatenator
The first few lines of my codes are:
from math import *
import exceptions
import pmag
import matplotlib
matplotlib.use("TkAgg")
import numpy as np
import matplotlib.pyplot as plt
Thanks a lot for all your help.
