无法通过python脚本和chaquopy在Android中启动stanfordtag的java.exe
我想要启动我的python脚本,它使用nltk和Stanford标记器分析文本数据。
问题是我没有启动复制的java.exe的权限。
启动stanfordtag的代码为:
#set java path in environment variables
java_path = fct.lib_dir + "java.exe"
os.environ['JAVAHOME'] = java_path
#load stanford NER
sn = StanfordNERTagger(
fct.lib_dir+"german.distsim.crf.ser.gz",
path_to_jar=fct.lib_dir+"stanford-ner.jar")
这是错误:

如何解决此问题?或者有没有其他选项可以访问复制的java.exe (从:C:Program FilesJavajdk-14insava.exe";指向:lib_dir=Join(目录名称(文件),";库文件/";) )在python脚本中打开窗口?
java_path = fct.lib_dir + "java.exe"
解决方案
遗憾的是,您需要做更多工作才能使此方法起作用。你需要提供一个完整的JRE,而不仅仅是java
可执行文件,而且它必须是为Android构建的,而不是Windows。我不知道有什么简单的方法可以做到这一点,所以我建议您考虑其他选项,例如:
- 将JAR添加到
app/libs
目录并从Java或Kotlim调用它 - 或只需使用其他标记器。
