I am using Python 2.4 with Numpy 0.9.8. Matpylib graphs function under these two version except when old numeric must be called to utilized the spline function in contouring the graphs leading to the error: Traceback (most recent call last): File "C:\File\XXX", line 3, in ? from scipy.sandbox.delaunay import * File "C:\Python24\lib\site-packages\scipy\__init__.py", line 32, in ? from numpy import oldnumeric File "C:\Python24\lib\site-packages\numpy\oldnumeric\__init__.py", line 3, in ? from compat import * File "C:\Python24\lib\site-packages\numpy\oldnumeric\compat.py", line 133, in ? from numpy import deprecate ImportError: cannot import name deprecate Scipy 0.5.0 seems to be compatible only with Numpy 101b, not version 0.9.8 and I have to switch version of Numpy to should I need to utilize Scipy, however certain matpylib graphs will not function. Upgrading Scipy to 0.5.2 and Numpy 101 has no negative effects on the programs I wrote or the matplotlib sample programs, however the following error message replaces the Import error above Matrix = matrix NameError:name matrix is not defined. Downgrading NUMPY to ver 9.6 produces even more problems. The best match seems to be Mumpy 0.9.8 used with SciPy 0.50 seems to be the best combination however it prohibits calling upon Oldnemeric which seems to be necessary to use the spline function. Does anyone have any idea on how to get around this? frbeaxs
