出现如下报错：
IndexError: only integers, slices (`:`), ellipsis (`...`), numpy.newaxis (`None`) and integer or boolean arrays are valid indices
在运行代码时，出现了报错：
代码：
from pypower.api import case39, runopfimport numpy as np'''第一级故障'''mpc1 = case39() #打开case39# #发电机故障# mpc['gen'][1, 7] = 0 #第二台发电机停运mpc1['branch'][0, 10] = 0 #第一条线路断线#运行线路result = runopf(mpc1)#判断是否存在问题#线路负载率weak = np.zeros(92).reshape((46, 2))load_pro = abs(result['branch'][:,13] / result['branch'][:,5])for i in range(46): if load_pro[i] >= 0.8: weak[i][0] = i #储存存在故障的线路标号 weak[i][1] = load_pro[i] #储存存在故障的线路负载率#选出负载率最大的作为第二级故障weak_max = np.max(weak[:, 1]) #第二级故障的负载率weakmax_index = np.argmax(weak[:, 1])weak_branch = weak[weakmax_index, 0] #第二级故障的线路'''第二级故障'''mpc2 = case39() #打开case39mpc2['branch'][0, 10] = 0 #第一条线路断线mpc2['branch'][weak_branch, 10] = 0 #第二条线路断线result = runopf(mpc2)结果
Traceback (most recent call last): File "C:\First semester of SeNIOr year\本科毕设\毕设参考论文学习笔记\fault.py", line 28, in mpc2['branch'][weak_branch, 10] = 0 #第二条线路断线IndexError: only integers, slices (`:`), ellipsis (`...`), numpy.newaxis (`None`) and integer or boolean arrays are valid indices 而本代码问题出在这里：
weakmax_index的类型如图所示：
均是浮点数。
将weak_branch转换为整数类型，用int函数：
weak_branch = int(weak[weakmax_index, 0]) #第二级故障的线路完整代码如下所示：
