c# - Deepclone issue with child object need deep serializing -

-

i've got issue when implementing deepclone serialization/deserialization way. fact: want class owndataset have deepclone instance, 2 below common procedures - constructor , getobjectdata declared:

protected owndataset(serializationinfo info, streamingcontext context)      : base(info, context)   {      dstype = datasettype.standard;       attributes =         new ownattributelist(            (list<ownattribute>)            info.getvalue("attributes", typeof (list<ownattribute>)));      islinkedds = info.getboolean("islinkedds");      pcaforscores = (pca)info.getvalue("pcaforscores", typeof(pca));      levels = (string[])info.getvalue("levels", typeof(string[]));   }   [securitypermission(securityaction.demand, serializationformatter = true)]   public override void getobjectdata(serializationinfo info,                                     streamingcontext context)   {      base.getobjectdata(info, context);       info.addvalue("attributes", new list<ownattribute>(attributes), typeof(list<ownattribute>));      info.addvalue("islinkedds", islinkedds);      info.addvalue("pcaforscores", pcaforscores);      info.addvalue("levels", levels);   }

please noticed owndataset has properities. 1 of them named "attributes", type ownattributelist - collection of ownattribute objects. when calling deepclone instance of owndataset, in constructor, properties type simple such islinkedds (boolean), levels (string[]) ... got out successfully. ok. more complex typed object, such atttributes (typed ownattributelist), got out incorrectly (number of element in collection still right each of elements null) ! experienced in case please me or give me hints. forgot ? attention & waiting help.

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,
