问题描述
我想用python笔记本,iggraph包来画画,示例代码在这里(我觉得是对的)
!pip install cairocffi
import cairocffi as cairo
corlor = []
for i in g.vs['name']:
if set([i]) < set(degree_15):
corlor.append('red')
elif set([i]) < set(degree_30):
corlor.append('rgba(255,0,0,0.5)')
elif set([i]) < set(degree_60):
corlor.append('orange')
else:
corlor.append('yellow')
ig.plot(g,
#'C:UsersVincent DuDesktopdegree_plot.jpg',
layout=geometry_layout,
vertex_label=g.vs['name'],
scale=1.0,
vertex_color=corlor,
vertex_frame_width=0.5,
edge_width=0.05,
vertex_label_size=ig.rescale(g.degree(),out_range=(1,12)),
vertex_size=ig.rescale(g.degree(),out_range=(5,25)),
bbox=(1200,800),
margin = 10,
)
仍然有一个错误。我不知道如何解决这个问题,谢谢!

我想我已经安装了开罗,但它仍然不能工作
推荐答案
Python3.7 venv:
(/home/victoria/venv/py37)$ python
Python 3.7.3 (default, Mar 26 2019, 21:43:19)
[GCC 8.2.1 20181127] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from igraph import *
>>> g = Graph.Famous("petersen")
>>> plot(g)
Traceback (most recent call last):

...
TypeError: plotting not available
- https://github.com/igraph/python-igraph/issues/129
- python + igraph "plotting not available"
- python - igraph plot not available (cairo already installed)
(/home/victoria/venv/py37)$ pip install cairocffi
...
Successfully installed cairocffi-1.0.2 cffi-1.12.3 pycparser-2.19
现在打印(忽略警告):
