R的coreNLP :: initCoreNLP()引发java.lang.OutOfMemoryError [英] R's coreNLP::initCoreNLP() throws java.lang.OutOfMemoryError

问题描述

coreNLP是用于与Standford的CoreNLP Java库进行接口的R包.必须执行的第一行(在使用library()命令加载适当的软件包之后)是initCoreNLP().不幸的是，这导致以下错误:

coreNLP is an R package for interfacing with Standford's CoreNLP Java libraries. The first line one must execute (after loading the appropriate packages with the library() command) is initCoreNLP(). Unfortunately, this results in the following error:

从edu/stanford/nlp/models/ner/english.conll.4class.distsim.crf.ser.gz中加载分类器... rJava中的错误::.jnew("edu.stanford.nlp.pipeline.StanfordCoreNLP ，基本名称(路径)): java.lang.OutOfMemoryError:超出了GC开销限制

Loading classifier from edu/stanford/nlp/models/ner/english.conll.4class.distsim.crf.ser.gz ... Error in rJava::.jnew("edu.stanford.nlp.pipeline.StanfordCoreNLP", basename(path)) : java.lang.OutOfMemoryError: GC overhead limit exceeded

请注意，这是此处列出的相同问题:(

Note, this is the same problem that is listed here: (initCoreNLP() method call from the Stanford's R coreNLP package throws error). In that case, however, the OP found that rebooting his machine made the problem disappear. This is not the case for me; I keep experiencing it even after a reboot.

还有其他人遇到这个问题并且可以提供解决方案或建议吗?

Has anyone else run into this and can provide a solution or suggestion?

推荐答案

以下是一些我发现的文档:

Here is some documentation I found:

https://cran.r-project.org/web/包/coreNLP/coreNLP.pdf

(特别是第7页)

您可以指定使用多少内存(来自文档):

You can specify how much memory you use (from the documentation):

initCoreNLP(libLoc, parameterFile, mem = "4g", annotators)

增加内存，我想问题将会消失.

Add more memory and I would imagine the problem will go away.
