你好，我试着用scikit fuzzy制作模糊系统，输出看起来运行良好，但是当我试图根据scikit fuzzy新api来计算它时，我的绘图没有响应。我记得上次我用scikit fuzzy时，我的图运行得很好，有什么问题吗？我的代码是不是缺少什么？在import numpy as np

import skfuzzy as fuzz

from skfuzzy import control as ctrl

# crisp set

keramaian = ctrl.Antecedent(np.arange(0, 30, 1), 'KERAMAIAN')

ukuran = ctrl.Antecedent(np.arange(0, 25, 1), 'UKURAN')

vol = ctrl.Consequent(np.arange(0, 100, 1), 'UKURAN VOLUME')

# fuzzyfication

ukuran['Kecil'] = fuzz.trimf(ukuran.universe, [0, 0, 13])

ukuran['Sedang'] = fuzz.trimf(ukuran.universe, [0, 12, 24])

ukuran['Besar'] = fuzz.trimf(ukuran.universe, [12, 24, 24])

keramaian['sunyi'] = fuzz.trimf(keramaian.universe, [0, 0, 15])

keramaian['Cukup Ramai'] = fuzz.trimf(keramaian.universe, [0, 15, 29])

keramaian['Berisik'] = fuzz.trimf(keramaian.universe, [15, 29, 29])

vol['Pelan'] = fuzz.trimf(vol.universe, [0, 0, 40])

vol['Sedang'] = fuzz.trimf(vol.universe, [30, 50, 70])

vol['Kencang'] = fuzz.trimf(vol.universe, [60, 99, 99])

# rule set

rule1 = ctrl.Rule(ukuran['Kecil'] & keramaian['Berisik'], vol['Kencang'])

rule2 = ctrl.Rule(ukuran['Kecil'] & keramaian['Cukup Ramai'], vol['Kencang'])

rule3 = ctrl.Rule(ukuran['Kecil'] & keramaian['Cukup Ramai'], vol['Kencang'])

rule4 = ctrl.Rule(ukuran['Sedang'] & keramaian['Berisik'], vol['Sedang'])

rule5 = ctrl.Rule(ukuran['Sedang'] & keramaian['Cukup Ramai'], vol['Sedang'])

rule6 = ctrl.Rule(ukuran['Sedang'] & keramaian['sunyi'], vol['Sedang'])

rule7 = ctrl.Rule(ukuran['Besar'] & keramaian['Berisik'], vol['Pelan'])

rule8 = ctrl.Rule(ukuran['Besar'] & keramaian['Cukup Ramai'], vol['Pelan'])

rule9 = ctrl.Rule(ukuran['Besar'] & keramaian['sunyi'], vol['Pelan'])

vol_suara_ctrl = ctrl.ControlSystem([rule1, rule2, rule3, rule4, rule5, rule6, rule7, rule8, rule9])

vol_suara = ctrl.ControlSystemSimulation(vol_suara_ctrl)

keramaian['sunyi'].view()

vol_suara.input['KERAMAIAN'] = int(input("Masukkan jumlah keramaian?\n"))

vol_suara.input['UKURAN'] = int(input("Masukkan ukuran speaker?\n"))

# defuzification

vol_suara.compute()

vol.view(sim=vol_suara)

print(vol_suara.output['UKURAN VOLUME'])
