qt - python crashed with Pyqt5 and QComboBox (QBasicTimer error) -

-

python crashed when close program error :

qbasictimer::start: qbasictimer can used threads started qthread

i havn't timer or thread in program.

and discover line make crashing :

self.combobox = qcombobox(self)

or

combobox = qcombobox(self)

or

combobox = qcombobox() self.mylayout.addwidget(combobox)

in otherword, when "draw" qcombobox, there crash when close program

if switch qcombobox classic widget (for example, qtoolbutton), there no crash

i work python 3 , pyqt5

(i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
