I installed scipy (and all the required libraries) and the following error
appears when i tried run a simple example which uses the optimize package of
scipy. I tried also numpy alone and it works ( at least for printing
numpy.array([10,20,10]))
error:
Traceback (most recent call last):
File "main_test.py", line 2, in <module>
from scipy import optimize
File
"/home/gberbeglia/python/Python-2.6.5/lib/python2.6/site-packages/scipy/optimize/__init__.py",

Any ideas on how to solve this problem? Thanks.
PS: the example is below:
import numpy
from scipy import optimize
a = numpy.array([10,20,10])
print a
def f_(x):
return x*x
x,f,d = optimize.fmin_l_bfgs_b(f_,[0.1],fprime=None, approx_grad = True,
bounds = [(-10000,10000)], iprint=30, maxfun=150000)
