Paste the contents of
"/sw/lib/python2.3/site-packages/matplotlib/numerix/_sp_imports.py" in
an email.

The contents of the file is:

from numpy import Int8, UInt8, \

Int16, UInt16, \

Int32, UInt32, \

Float32, Float64, \

Complex32, Complex64, \

Float, Int, Complex

class _TypeNamespace:

"""Numeric compatible type aliases for use with extension functions."""

Int8 = Int8

UInt8 = UInt8

Int16 = Int16

UInt16 = UInt16

Int32 = Int32

UInt32 = UInt32

Float32 = Float32

Float64 = Float64

Complex32 = Complex32

Complex64 = Complex64

nx = _TypeNamespace()

from numpy import inf, infty, Infinity

infinity = Infinity

What version of matplotlib do you have? Look in
"/sw/lib/python2.3/site-packages/matplotlib/__init__.py" and look for
"__version__" to find out.

The version is 0.87.3.

I replaced the import part in the file _sp_import.py to be:

try:

from numpy.oldnumeric import Int8, UInt8, \

Int16, UInt16, \

Int32, UInt32, \

Float32, Float64, \

Complex32, Complex64, \

Float, Int, Complex

except ImportError:

from numpy import Int8, UInt8, \

Int16, UInt16, \

Int32, UInt32, \

Float32, Float64, \

Complex32, Complex64, \

Float, Int, Complex

Then I can get through this file. But there are a lot of other files that need to be modified, i.e., replacing the numpy by numpy.oldnumeric. I guess this matplotlib is just too old but I could not find a right version for it. I think I will try to do it in another machine that use python2.4 or python2.5. Or use other viewers to view the results.

Thank you very much for your times. I really appreciate it.
