Socket Error loading StanfordCoreNLP

[gstoica27]

Hi,

I am having a big issue involving the socket in the first few lines in the "simple usage" example:

from stanfordcorenlp import StanfordCoreNLP

nlp = StanfordCoreNLP(r'/Users/georgestoica/Desktop/stanford-corenlp-full-2018-10-05')

sentence = 'Guangdong University of Foreign Studies is located in Guangzhou.'
print('Tokenize: {}'.format(nlp.word_tokenize(sentence)))

Problem: (I have to run with sudo because otherwise I get psutils issues as in #26) When I run the python script containing the above 4 lines I receive the following error:

Traceback (most recent call last):
  File "/Users/georgestoica/Library/Preferences/PyCharm2019.1/scratches/scratch_57.py", line 3, in <module> <-- "This is the nlp = StanfordCoreNLP(...)"
    nlp = StanfordCoreNLP(r'/Users/georgestoica/Desktop/stanford-corenlp-full-2018-10-05')
  File "/opt/anaconda3/lib/python3.7/site-packages/stanfordcorenlp/corenlp.py", line 119, in __init__
    while sock.connect_ex((host_name, self.port)):
socket.gaierror: [Errno 8] nodename nor servname provided, or not known

Based on my searches online, people have suggested solutions involving getting the hostname from the socket package. I've tried this by changing line 114 in corenlp.py

host_name = urlparse(self.url).hostname

to host_name = socket.gethostbyname('MacBook-Pro-10.local') or host_name = socket.gethostname()

Interestingly, these replacements allow the "nlp = StanfordCoreNLP(...)" line to pass. However, as soon as the script reaches line 6:

print('Tokenize: {}'.format(nlp.word_tokenize(sentence)))

It throws the following error of not being able to connect to the server:

I've searched if people have had similar problems, but haven't been able to find anything very usable.

System: OSX 10.14.6 (anaconda 3) python 3.7.4

Any help or suggestions would be greatly appreciated! Thanks!

Did you solve the problem? I am having the same issue here.

I had the same problem. When I changed to run on a 8GB memory computer, the problem disappeared.
