Question

我正在尝试加载程序包StanfordCoreNLP以正确解析其页面中显示的电影评论（https://nlp.stanford.edu/sentiment/treebank.html）:(我使用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:

    globals = debugger.run(setup['file'], None, None, is_module)

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

我试过

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

但它没有帮助。任何想法??

谢谢！

Answer 1

我遇到了同样的问题，可以通过使用sudo来运行代码来使其正常工作，如下所示：

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

希望这对您也有用。

Answer 2

这里也有同样的问题。

对此的大量讨论指向https://github.com/ContinuumIO/anaconda-issues/issues/1984，建议更新到最新的Navigator，并以root身份运行（通过sudo）。

我已经尝试过两者并且看不到任何改变（你可能更幸运）。

https://github.com/Lynten/stanford-corenlp/issues/26引用了corenlp.py的调整版本，声称可以避免这个问题，但我还没有让它工作。

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.')

替换此行：

        self.port = 9999

另一种解决方案是使用sudo命令行运行StanfordCoreNLP。

psutil.AccessDenied尝试加载StanfordCoreNLP时出错
