I'm getting odd behavior when I try to use fmin and pylab in the same program.
The issue is illustrated in the code snippet below. As written, fmin won't
work: the "print xopt" simply returns the contents of x0 as assigned in the
line before fmin. If the "from pylab import *" line is commented out, however,
then fmin runs as expected.
I'm running python 2.7.2 on a MacBook Pro with a recent install & upgrade of
scipy and matplotlib via macports. Any suggestions would be appreciated.
-------------------------------------
#!/opt/local/bin/python
from scipy import *
from scipy.optimize import fmin
import matplotlib
matplotlib.use('MacOSX')
from pylab import *
def rosen(x): # The Rosenbrock function
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)
print xopt
