psutil.AccessDenied尝试加载StanfordCoreNLP时出错

Question

[我正在尝试加载StanfordCoreNLP软件包，以便对其页面（https://nlp.stanford.edu/sentiment/treebank.html）中显示的电影评论进行正确的解析：（我正在使用MAC）

nlp = StanfordCoreNLP("/Users//NLP_models/stanford-corenlp-full-2018-01-31")

但是得到错误：

Traceback (most recent call last):
  File "/Users/anaconda3/lib/python3.6/site-packages/psutil/_psosx.py", line 295, in wrapper
    return fun(self, *args, **kwargs)
  File "/Users/anaconda3/lib/python3.6/site-packages/psutil/_psosx.py", line 480, in connections
    rawlist = cext.proc_connections(self.pid, families, types)
PermissionError: [Errno 1] Operation not permitted

During handling of the above exception, another exception occurred:

    raise AccessDenied(self.pid, self._name)
psutil.AccessDenied: psutil.AccessDenied (pid=5488)

我尝试过

conda update conda
conda update anaconda-navigator
conda update navigator-updater

但是没有帮助。有什么想法吗？

谢谢！

Answer 1

我有同样的问题，我可以通过使用sudo如下运行代码来使其正常工作：

sudo /Users/edamame/workspace/git/chinese_nlp/venv/bin/python3 chinese_segmenter1.py

希望这也对您有效。

Answer 2

这里有同样的问题。

对此的很多讨论都指向https://github.com/ContinuumIO/anaconda-issues/issues/1984，它建议更新到最新的Navigator，并以root身份运行（通过sudo）。

我都尝试过，但完全没有发现变化（您可能会更幸运）。

[https://github.com/Lynten/stanford-corenlp/issues/26引用了corenlp.py的经过调整的版本，该版本声称可以避免该问题，尽管我也没有使其工作。

Answer 3

此问题似乎是特定于Mac OS X的，它不允许Python检查当前端口。

注释corenlp.py文件的这段代码：

        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.')

用此行替换：

        self.port = 9999

另一种解决方案是使用sudo命令行运行StanfordCoreNLP。
