Question

我正在使用Stanford Core NLP服务器。我想从python文件启动它。

要从命令提示符启动它，我使用：

cd C:\ProgramData\Anaconda3\stanford-corenlp-full-2018-10-05
java -mx1g -cp "*" edu.stanford.nlp.pipeline.StanfordCoreNLPServer -port 9000 -tiemout 15000

我尝试从包含以下代码的 python文件启动它：

import subprocess
subprocess.call([r'C:\Users\maell\PycharmProjects\Preprocessing\launch_NLP.bat'])

带有包含以下内容的launch_NLP.bat：

cd C:\ProgramData\Anaconda3\stanford-corenlp-full-2018-10-05
java -mx1g -cp "*" edu.stanford.nlp.pipeline.StanfordCoreNLPServer -port 9000 -tiemout 15000

输出如下：

C:\Users\maell\PycharmProjects\Pre-processing>cd                     
C:\ProgramData\Anaconda3\stanford-corenlp-full-2018-10-05 

C:\ProgramData\Anaconda3\stanford-corenlp-full-2018-10-05>java -mx1g -cp "*" edu.stanford.nlp.pipeline.StanfordCoreNLPServer -port 9000 -tiemout 15000

[Thread-0] INFO CoreNLP - CoreNLP Server is shutting down.

如何让我的服务器运行，并且在线路经过后不关闭？

Answer 1

似乎是一个更简单的错误：

java.net.BindException: Address already in use: bind

要么终止在端口9000上运行的进程，要么在另一个端口上运行的进程，下一次应该可以运行。

Answer 2

java.net.BindException：地址已在使用中：bind

该端口已被使用，请尝试使用launch_NLP.bat中的另一个端口（例如9001）。

如何使用python代码启动服务器？
