无法从networkx导入版本

Question

我试图从networkx导入release，但在ipython notebook上得到以下错误。我已经成功安装了networkx。有人能帮上忙吗？

代码：

import networkx as nx
from networkx import release
print "NetworkX version:     %6.6s (need at least 1.7)" % nx.__version__

错误：

Answer 1

在导入networkx 1.9.1时，我遇到了相同的错误。只需重新安装即可解决此问题。

pip uninstall networkx && pip install networkx

Answer 2

只需打开cmd并运行此命令

python -m pip install networkx --upgrade pip
