SNAP macos

1 创建python27环境

• 用conda创建虚拟环境：conda create -n python27 python=2.7
• 查看虚拟环境配置情况：conda info -e
• 进入python2.7环境：source activate python27

2 下载SNAPpy代码

地址：https://snap.stanford.edu/snappy/release/
下载完后解压

3 配置插件

• 安装homebrew：ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
• 安装graphviz： brew install graphviz
• 安装gnuplot：brew install gnuplot

4 Snap.py安装

到snap-4.1.0-4.1-macosx10.13.2-x64-py2.7目录下，执行命令：python setup.py install

5 运行测试

运行代码

status = False
try:
    import snap
    version = snap.Version
    i = snap.TInt(5)
    if i == 5:
        status = True
except:
    pass

if status:
    print "SUCCESS, your version of Snap.py is %s" % (version)
else:
    print "*** ERROR, no working Snap.py was found on your computer"

结果：

SUCCESS, your version of Snap.py is 4.1.0

2测试gnuplot works

import snap

G = snap.GenPrefAttach(100000, 3)
snap.PlotInDegDistr(G, "pref-attach", "PrefAttach(100000, 3) in Degree")

3测试Graphviz

import snap

G = snap.GenGrid(snap.PUNGraph, 5, 3)
snap.DrawGViz(G, snap.gvlDot, "grid5x3.png", "Grid 5x3")

比较坑的一点是，它生成的是png文件，在相对目录下，注意查看！！！

多次运行会报错，如下：

Exception in thread ptvsd.stopping (most likely raised during interpreter shutdown):%

证明文件可能已经生成。
