-

my eclipse galileo installation has started giving me problems of sudden.

yesterday unable start tomct6 server , today unable create dynamic web project.

i following error

    selected wizard not started.   plug-in "org.eclipse.jst.servlet.ui" unable instantiate class "org.eclipse.jst.servlet.ui.project.facet.webprojectwizard".   java.lang.nullpointerexception

my eclipse shared colleagues, issue ? installed m2 sonatype plug in maven 2.

have updated eclipse recently? quick googling seems mixing galileo updates helios in modules causing error message. suggest download eclipse helios , point current workspace.

i want make logharitmic fit. keep getting runtime error: optimal parameters not found: number of calls function has reached maxfev = 1000 i use following script. can tell me go wrong? use spyder still beginner. import math import matplotlib mpl scipy.optimize import curve_fit import numpy np #data f1=[735.0,696.0,690.0,683.0,680.0,678.0,679.0,675.0,671.0,669.0,668.0,664.0,664.0] t1=[1,90000.0,178200.0,421200.0,505800.0,592200.0,768600.0,1036800.0,1371600.0,1630800.0,1715400.0,2345400.0,2409012.0] f1n=np.array(f1) t1n=np.array(t1) plt.plot(t1,f1,'ro',label="original data") # curvefit def func(t,a,b): return a+b*np.log(t) t=np.linspace(0,3600*24*28,13) popt, pcov = curve_fit(func, t, f1n, maxfev=1000) plt.plot(t, func(t, *popt), label="fitted curve") plt.legend(loc='upper left') plt.show() your original data t1 , f1 . therefore curve_fit should given t1 second argument, not t . popt, pcov = curve_fit(func,...
