geatpy 不能多次遍历循环调用吗？

写了一个循环多次调用，但第二次的时候就会卡住了，终止之后出现如下情况： File "/Users/bytedance/PycharmProjects/pythonProject/optimizeVar.py", line 46, in [population, obj_trace, var_trace] = myAlgorithm.run(prophetPop) # 执行算法模板，插入先知种群 File "/Users/bytedance/.local/lib/python3.5/site-packages/geatpy/templates/soeas/DE/DE_currentToBest_1_bin/soea_DE_currentToBest_1_bin_templet.py", line 65, in run return self.finishing(population) # 调用finishing完成后续工作并返回结果 File "/Users/bytedance/.local/lib/python3.5/site-packages/geatpy/Algorithm.py", line 319, in finishing ea.trcplot(self.obj_trace, [['种群个体平均目标函数值', '种群最优个体目标函数值']], xlabels = [['Number of Generation']], ylabels = [['Value']], gridFlags = [[False]]) File "core/trcplot.py", line 121, in trcplot.trcplot File "/opt/anaconda3/envs/python35/lib/python3.5/site-packages/matplotlib/pyplot.py", line 253, in show return _show(*args, **kw) File "/opt/anaconda3/envs/python35/lib/python3.5/site-packages/matplotlib/backend_bases.py", line 3266, in show cls.mainloop() File "/opt/anaconda3/envs/python35/lib/python3.5/site-packages/matplotlib/backends/_backend_tk.py", line 1037, in mainloop Tk.mainloop() File "/opt/anaconda3/envs/python35/lib/python3.5/tkinter/init.py", line 414, in mainloop _default_root.tk.mainloop(n)
