我正在嘗試使用scipy的ode求解器來(lái)繪制2D方程組之間的相互作用。我正在嘗試通過(guò)以下代碼塊更改傳遞給求解器的參數(shù)：# define maximum number of iteration steps for ode solver iterationm = 1 #power of iterationN = 2**m #number of steps# setup a try-catch formulation to increase the number of steps as needed for solution to convergewhile True:    try:        z = ode(stateEq).set_integrator("vode",nsteps=N,method='bdf',max_step=5e5)        z.set_initial_value(x0, t0)        for i in range(1, t.size):            if i%1e3 == 0:                print 'still integrating...'            x[i, :] = z.integrate(t[i]) # get one more value, add it to the array            if not z.successful():                raise RuntimeError("Could not integrate")        break    except:        m += 1        N = 2**m        if m%2 == 0:            print 'increasing nsteps...'            print 'nsteps = ', N運(yùn)行它不會(huì)中斷while循環(huán)。它會(huì)永遠(yuǎn)增加nstep，而系統(tǒng)永遠(yuǎn)也不會(huì)解決。我認(rèn)為，如果不將其放入while循環(huán)中，則系統(tǒng)會(huì)得到解決，因?yàn)榻鉀Q方案已被標(biāo)繪。while循環(huán)是否必要？我的求解器公式不正確嗎？
