无法在R中初始化CoreNLP [英] Cannot Initialize CoreNLP in R

问题描述

我无法在运行High Sierra的Mac上的R中访问 coreNLP 。我不确定问题是什么，但似乎每次我再次尝试让 coreNLP 工作时，我都面临着不同的错误。我有JDK 9.0.4。请参阅下面的代码，了解我正在尝试做什么，以及阻止我的错误。

I am unable to access coreNLP in R on a Mac running High Sierra. I am uncertain what the problem is, but it seems that every time I try again to get coreNLP to work, I am faced with a different error. I have JDK 9.0.4. Please see my code below for what I am attempting to do, and the error that stops me.

我以前的尝试我能够获得 initCoreNLP （）运行并加载包的某些元素，但在其他元素上会失败。当我然后尝试运行 annotateString（）时，它会抛出错误错误必须用'int CoreNLP'初始化！ 。

My previous attempt I was able to get initCoreNLP() to run and load some elements of the packages, but it would fail on others. When I then attempted to run annotateString(), it would throw the error Error Must initialize with 'int CoreNLP'!.

我已多次下载并重新下载 coreNLP Java档案，但仍然没有运气！参见位于 /Library/Frameworks/R.framework/Versions/3.4/Resources/library/coreNLP <我 coreNLP ř包文件夹的内容图像/ code>。

I have downloaded and re-downloaded the coreNLP Java archive many times and still no luck! See image for contents of my coreNLP R package folder located at /Library/Frameworks/R.framework/Versions/3.4/Resources/library/coreNLP.

您知道我如何成功初始化 coreNLP ？

Do you know how I can successfully initialize coreNLP?

dyn.load("/Library/Java/JavaVirtualMachines/jdk-9.0.4.jdk/Contents/Home/lib/server/libjvm.dylib")

library(NLP)
library(coreNLP)

推荐答案

根据我们的讨论。

我的感觉是你的Java / R配置依赖问题。因此，似乎 rJava 依赖于使用的 java 版本和 coreNLP 依赖于 rJava 。

My sense is your Java / R configuration dependency issue. Thus, it appears that rJava is dependent on the version of java used and coreNLP is dependent on rJava.

java <- rJava <- coreNLP

因此我们可以将dlynlib版本设置为1.8.X，卸载rJava，重新安装rJava然后重新安装coreNLP。

thus we can set the dlynlib version to 1.8.X, uninstall rJava, reinstall rJava then reinstall coreNLP.

dyn.load('/Library/Java/JavaVirtualMachines/jdk1.8.0_162.jdk/Contents/Home/jre/lib/server/libjvm.dylib')

remove.packages("rJava")
install.packages("rJava")

ipak <- function(pkg){
  new.pkg <- pkg[!(pkg %in% installed.packages()[, "Package"])]
  if (length(new.pkg))
    install.packages(new.pkg, dependencies = TRUE)
  sapply(pkg, require, character.only = TRUE)
}

# usage
packages <- c("NLP", "coreNLP", "rJava")
ipak(packages)

.jinit()
.jcall("java/lang/System","S","getProperty","java.version")

# run the follwoing command once
# downloadCoreNLP() # <- Takes a while...

initCoreNLP()
example(getSentiment)
sIn <- "Mother died today. Or, maybe, yesterday; I can't be sure."
annoObj <- annotateString(sIn)
