在 Pycharm 中使用 StanfordCoreNLP 时 psutil.AccessDenied? [英] psutil.AccessDenied when using StanfordCoreNLP in Pycharm?

问题描述

# coding=utf-8

from stanfordcorenlp import StanfordCoreNLP

nlp = StanfordCoreNLP(r'/Users/silas/stanford-corenlp/', lang='zh')

sentence = '清华大学位于北京。'
print nlp.word_tokenize(sentence)
print nlp.pos_tag(sentence)
print nlp.ner(sentence)
print nlp.parse(sentence)
print nlp.dependency_parse(sentence)

nlp.close()

我使用的是 Mac.Java、NLKT 和 Stanforcorenlp 工具包都已准备就绪.当我测试项目时，错误出来了.

I'm using Mac. Java, NLKT, and Stanforcorenlp toolkit are all ready. When I'm testing the project, the error came out.

Traceback (most recent call last):
  line 5, in <module>
    nlp = StanfordCoreNLP(r'/Users/silas/stanford-corenlp/', lang='zh')
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/stanfordcorenlp/corenlp.py", line 79, in __init__
    if port_candidate not in [conn.laddr[1] for conn in psutil.net_connections()]:

    return _psplatform.net_connections(kind)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/psutil/_psosx.py", line 255, in net_connections
    cons = Process(pid).connections(kind)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/psutil/_psosx.py", line 347, in wrapper
    raise AccessDenied(self.pid, self._name)
psutil._exceptions.AccessDenied: psutil.AccessDenied (pid=25422)

我猜是因为 Pycharm 项目不是在 root 用户下运行的.但是如何配置 IDE 来解决问题?

I guess it is because the Pycharm project isn't running under a root user. But how can I configure the IDE to fix the problem?

推荐答案

这个问题似乎是 Mac OS X 特有的，它不允许 Python 检查当前端口.

This problem seems to be specific to Mac OS X which would not allow Python to check the current port.

注释 corenlp.py 文件的这部分代码:

Comment this portion of code of corenlp.py file:

        if self.port is None:
        for port_candidate in range(9000, 65535):
            if port_candidate not in [conn.laddr[1] for conn in psutil.net_connections()]:
                self.port = port_candidate
                break

        if self.port in [conn.laddr[1] for conn in psutil.net_connections()]:
            raise IOError('Port ' + str(self.port) + ' is already in use.')

用这一行替换:

        self.port = 9999

另一种解决方案是使用 sudo 命令行运行 StanfordCoreNLP.

Another solution is to run StanfordCoreNLP with a sudo command line.
