I am typically trying to something like

min = optimize.fmin_powell(test_arg,(1.0,2.0), ((5.0,6.0),))
This works with optimize.fmin, but fails with optimize.fmin_powell.
Works for me.

Doesn't work for me. Debian, python 2.4.1, Debian's scipy packages:

TypeError: test_arg() takes exactly 2 arguments (3 given)
Could you also copy-and-paste the code that you ran to yield this error? Because it looks to me like you may have executed min = optimize.fmin_powell(test_arg,(1.0,2.0), (5.0,6.0)) instead. -- Robert Kern rkern@ucsd.edu "In the fields of hell where the grass grows high Are the graves of dreams allowed to die." -- Richard Harter
