Scipy version import minimize

UPDATE  ------

I found that maybe optimize is not implemented totally. I can do this for instance :

from scipy.optimize import fmin

def rosen(x):
return sum(100.0*(x[1:]-x[:-1]**2.0)**2.0 + (1-x[:-1])**2.0)

x0 = [1.3, 0.7, 0.8, 1.9, 1.2]
xopt = fmin(rosen, x0, xtol=1e-8)

print xopt

no problem but when in try the minimize function, i get the error message :

from scipy.optimize import optimize

Message: cannot import minimize from scipy.optimize

To make it work in the first step (describe in an other post) 

>>> http://www.grasshopper3d.com/forum/topics/scipy-and-numpy

I edit the script in order to install all the eggs. they don't have all the package and you have to install the scipy-1.0.0-2.egg instead of scipy-1.0.0-1.egg. Optimize is missing in the first version.

So is it possible that in scipy.optimise minimize is not operational?

Hi Tristan

>>So is it possible that in scipy.optimise minimize is not operational?

This is possible; but I would really just ask Enthought to make sure. They are the developers of that library.
Thanks!

Hi, 

I got exactly the same problem.

from scipy.optimize import optimize

Message: cannot import minimize from scipy.optimize

If you have any update on this, please let us know.

Thanks, 

Florian

I import fmin simply with:

from scipy import fmin

However, if I try:

from scipy.optimize import fmin

I get "cannot import optimize from scipy"
