{"firstName": "Peter", "lastName": "Jones"}
],
"manager": [
{"firstName": "John", "lastName": "Doe"},
{"firstName": "Anna", "lastName": "Smith"},

我试图打开Android设备监视器,工作室向我展示了这条消息= -O:

它让我感到惊讶,因为如果我没有安装任何Java,我怎么能够开发Android应用程序?!实际上,Android Studio附带了捆绑的JDK/JRE(位于/Applications/Android Studio.app/Contents/jre/jdk/Contents/Home),但系统找不到它:执行usr/libexec/java_home给出

设置$JAVA_HOME到/Applications/Android Studio.app/Contents/jre/jdk/Contents/Home没有帮助- source .bash_profile不喜欢,这是一个目录.

NLTK文档和示例的流行数量主要用于词典化和词干化,但在规范化的问题上非常稀少:
请指点我在NLTK挖掘的地方.欢迎任何用于上述目的的NLTK等同物(JAVA或任何其他).谢谢.
UPD.我已经编写了一个文本规范化的python库,用于文本到语音的目的https://github.com/soshial/text-normalization.它也可能适合你.
代码非常简单.它不应该有任何泄漏,因为所有都是在函数内部完成的.并且不返回任何结果.我有一个函数遍历文件中的所有行(~20 MiB)并将它们全部放入列表中.

import codecs
corpus = []
corpus_file = codecs.open(path_to_dir + filename, 'r', 'iso-8859-15')
newline = corpus_file.readline().strip()
while newline != '':
# we put into @article a @newline of file and some other info
# (i left those lists blank for readability)

这是我的布局代码。当我单击可扩展列表视图时,它不会扩展。但是,如果我增加列表的高度,它将扩展。有没有办法通过代码动态增加列表的高度?我可以在布局的中间进行扩展吗?因为如果我增加高度,它只会在折叠列表中添加不必要的空白。
