从 Python Extension Packages for Windows – Christoph Gohlke 下载的windows上的igraph安装文件

python_igraph‑0.7.1.post6‑cp35‑none‑win_amd64.whl

使用igraph的plot函数画图出错，错误信息为

AttributeError: 'bytes' object has no attribute 'encode'

提示 AttributeError: ‘bytes’ object has no attribute ‘encode’、

这是因为，python3中，编码的时候区分了字符串和二进制

将Anaconda3\lib\site-packages\igraph\drawing\__init__.py的第354行中的 encode 改为 decode 就可以了
