Index out of range error in Python (IndexError: list index out of range)

Question

我在这里似乎找不到我超出范围的问题：

layerZ = [layer_1,layer_2,layer_3,layer_4,layer_5,layer_6,layer_7,layer_8,layer_9,layer_10,layer_11,layer_12,layer_13]
    for x in range(0, 12):
        layerZ_total = [np.size(layerZ[x])]
        layerZ_sp = [np.count_nonzero(layerZ[x]==0)]
        layerZ_nonSp = [np.count_nonzero(layerZ[x])]

        #Printing the results on scree to trace
        print "Layer:",x+1,"Threshhold:",repr(ths),"Total Parameters: ",layerZ_totParam[x],"# Sp: ",layerZ_sp[x],"# Remained : ",layerZ_nonSp[x],"Sp %: ",float(layerZ_sp[x])/layerZ_total[x]

Answer 1

这应该有帮助：

layerZ = [layer_1,layer_2,layer_3,layer_4,layer_5,layer_6,layer_7,layer_8,layer_9,layer_10,layer_11,layer_12,layer_13]

layerZ_total = []
layerZ_sp = []
layerZ_nonSp = []


for x in range(0, 12):
    layerZ_total.append(np.size(layerZ[x]))
    layerZ_sp.append(np.count_nonzero(layerZ[x]==0))
    layerZ_nonSp.append(np.count_nonzero(layerZ[x]))

    #Printing the results on scree to trace
    print "Layer:",x+1,"Threshhold:",repr(ths),"Total Parameters: ",layerZ_total[x],"# Sp: ",layerZ_sp[x],"# Remained : ",layerZ_nonSp[x],"Sp %: ",float(layerZ_sp[x])/layerZ_total[x]

在您的代码中，列表 layerZ_total、layerZ_sp 和 layerZ_nonSp 每次在循环内都使用单个值重新初始化，因此在 index 0 处仅包含一个元素在它们内部，当您尝试访问某些 x index 时，会弹出 list index out of range 错误。

并且如果您要对 layerZ 列表中的每个 layer_* 进行处理（取决于您的要求），您需要 range(0, 13) 就像在执行此操作后一样 x将采用 0 到 12 的值，从而处理 layerZ 列表中的每个 layer
