igraph load 无法读取保存的graph attr

啥b igraph

igraph.load无法从igraph.save的图中读取保存的graph attr。必须要自己再另外写一个接口来读取，接口给您：

def FUCK_U_IGraphLoad(path,graph_attr_num):
    with open(path, "r") as f:
        data=f.readlines()
        count=0
        for line in data:
            gattr=line.split()
            if gattr[0]=="label":
                label=int(gattr[1])
                count+=1
            if gattr[0]=="feature":
                feature=line.split("feature")[1]
                count+=1
            if count==graph_attr_num:
                return label, feature

label,feature=FUCK_U_IGraphLoad("G_N2_E2_NL1_GL5_18.gml")
print(label,feature)
>>>0  "[' 22.000000, 32.941603, 75.110000,  1.700000,  3.405000,188.800000,  6.000000, 11.000000,  5.000000,  9.000000,  5.000000,  8.000000,  9.000000,  4.000000,  9.000000,  6.000000, 11.000000,  5.000000\n', ' 24.000000, 30.484920, 79.090000, -4.430000,  3.513000,221.700000,  9.000000,  9.000000,  6.000000, 11.000000,  8.000000,  5.000000,  6.000000,  7.000000, 11.000000,  8.000000, 10.000000,  6.000000\n']"

再利用上一篇将这里的string feature转化成float feature即可。

这里的graph数据如下，可根据自己的实际数据修改if判断部分
