使用Jupyter notebook上载Networkit python模块时出错

Question

我用conda install -c vgauthier networkit安装了Networkit模块。如果我将其导入到notebook (import networkit as nk)中，则会出现以下错误：

---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
<ipython-input-2-a4c0096fb06c> in <module>()
----> 1 import networkit as nk

     41 # local imports

      1 # extension imports
----> 2 from _NetworKit import Graph, SpanningForest, GraphTools, RandomMaximumSpanningForest, UnionMaximumSpanningForest

ImportError: dlopen(//anaconda/envs/py36/lib/python3.6/site-packages/_NetworKit.cpython-36m-darwin.so, 2): Library not loaded: @rpath/libomp.dylib

  Reason: image not found

有人能解释为什么吗？​

Answer 1

我碰巧在通过pip的networkit上遇到了同样的问题。这是因为anaconda安装的networkit没有正确链接到您的gcc编译器，一个简单的修复方法是下载networkit的源代码并运行python3 setup.py install来安装它。

Answer 2

我也遇到了同样的问题：https://github.com/kit-parco/networkit/issues/172

这是因为蟒蛇。使用以下命令重新安装：

conda install -c vgauthier networkit
