我在使用 StanfordCoreNLP 的时候遇到了需要管理员权限才能成功运行程序的问题.

from stanfordcorenlp import StanfordCoreNLP
core_nlp = StanfordCoreNLP('library/english')

解决方案如下:

Step 1: 生成一个 notebook 的配置文件

1
jupyter notebook --generate-config

Step 2: 修改配置文件

1
vim ~/.jupyter/jupyter_notebook_config.py

通过 vim 打开配置文件并将文件中的 #c.NotebookApp.allow_root = False 去注释, 然后将 False 改为 True.

Step 3: 在 terminal 以管理员方式运行 notebook

1
sudo python -m IPython notebook
