python - When timeout is more than 10,000 in pycorenlp I get "java.net.UnknownHostException: server: server: unknown error" on Linux (runs fine on OS X). Why? -

-

i trying run pycorenlp on long text. in order avoid getting corenlp request timed out. document may long error message, increased stanford corenlp specifying timeout.

here code use (it's simplified version of pycorenlp's example.py):

from pycorenlp import stanfordcorenlp  if __name__ == '__main__':     nlp = stanfordcorenlp('http://localhost:9000')     text = (         'pusheen , smitha walked along beach. pusheen wanted surf,'         'but fell off surfboard.')     output = nlp.annotate(text, properties={         'timeout': '10001' # setting timeout 10000 or below "fixes" issue.         'annotators': 'tokenize,ssplit,pos,depparse,parse',         'outputformat': 'json'     })     print(output)

it outputs server: unknown error. server log contains:

java.net.unknownhostexception: server: server: unknown error     @ java.net.inetaddress.getlocalhost(inetaddress.java:1505)     @ edu.stanford.nlp.pipeline.stanfordcorenlpserver$corenlphandler.handle(stanfordcorenlpserver.java:393)     @ com.sun.net.httpserver.filter$chain.dofilter(filter.java:79)     @ sun.net.httpserver.authfilter.dofilter(authfilter.java:83)     @ com.sun.net.httpserver.filter$chain.dofilter(filter.java:82)     @ sun.net.httpserver.serverimpl$exchange$linkhandler.handle(serverimpl.java:675)     @ com.sun.net.httpserver.filter$chain.dofilter(filter.java:79)     @ sun.net.httpserver.serverimpl$exchange.run(serverimpl.java:647)     @ java.util.concurrent.threadpoolexecutor.runworker(threadpoolexecutor.java:1142)     @ java.util.concurrent.threadpoolexecutor$worker.run(threadpoolexecutor.java:617)     @ java.lang.thread.run(thread.java:745) caused by: java.net.unknownhostexception: server: unknown error     @ java.net.inet6addressimpl.lookupallhostaddr(native method)     @ java.net.inetaddress$2.lookupallhostaddr(inetaddress.java:928)     @ java.net.inetaddress.getaddressesfromnameservice(inetaddress.java:1323)     @ java.net.inetaddress.getlocalhost(inetaddress.java:1500)     ... 10 more

the stanford core nlp server launched using:

java -mx4g -cp "*" edu.stanford.nlp.pipeline.stanfordcorenlpserver 9000

i don't want segment text smaller texts.

is there way set timeout higher 10000? (i.e. higher 10 seconds)

it works fine on mac os x 10.10 (java version "1.8.0_60"): issue arises in ubuntu 14.04 (java version "1.8.0_77"). both have python 2.7 pycorenlp 0.2.0 , stanford corenlp version 3.6.0.

to clear, not seeing issue if run server on macbook?

then appears issue machine running server on. server code trying call:

inetaddress.getlocalhost().gethostname()

and getting exception.

here thread found had similar issue:

inetaddress.getlocalhost() throws unknownhostexception

what in /etc/hosts file on machine you're trying run server?

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
