psutil.AccessDenied Error while trying to load StanfordCoreNLP

问题

I'm trying to load the package StanfordCoreNLP to get the correct parsing for the movie reviews presented in their page (https://nlp.stanford.edu/sentiment/treebank.html): (I'm using MAC)

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

But get the error:

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)

I tried

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

But it didn't help. Any ideas??

Thanks!!

回答1:

I have the same problem, and I got it work by running the code using sudo like below:

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

Hope this works for you as well.

回答2:

Same problem here.

A lot of discussion of this points to https://github.com/ContinuumIO/anaconda-issues/issues/1984, which suggests updating to the latest Navigator, and running as root (via sudo).

I've tried both and see no change at all (you may be more fortunate).

https://github.com/Lynten/stanford-corenlp/issues/26 references a tweaked version of corenlp.py that claims to avoid the problem, though I haven't gotten it to work either.
