例子中ppi数据+faiss检索 部分执行报错

[macroxmu]

使用https://github.com/alibaba/euler/wiki/%E5%BF%AB%E9%80%9F%E5%BC%80%E5%A7%8B 中提供的embedding输出与在Faiss中进行检索部分的代码，与文档中的ppi示例数据执行报错，执行流程如下：

[lsy@localhost data]$ python -m tf_euler \

>   --max_id 56944 --feature_idx 1 --feature_dim 50 --label_idx 0 --label_dim 121 \
>   --model graphsage_supervised --mode save_embedding

@macroxmu 这里的例子和目前的代码有一些不一致，麻烦试一下：index = faiss.IndexFlatIP(256)
