无法在R中安装pattern.nlp包

Question

我正在尝试在R中安装pattern.nlp包，但是在进行时会出现几个错误。这个包用于python库，所以我改变了环境变量的路径。但在运行以下代码时，我收到错误。

$

x <- pattern_sentiment("i really really hate iphones", language = "english")



Error in data.table::setDF(score) : 
  All elements in argument 'x' to 'setDF' must be of same length
In addition: Warning messages:
1: In pyConnectionCheck() : R isn't connected to Python!

2: In pyConnectionCheck() : R isn't connected to Python!

3: In pyConnectionCheck() : R isn't connected to Python!

4: In pyConnectionCheck() : R isn't connected to Python!

Answer 1

使用pyIsConnected（）函数检查Python是否从R连接。如果没有，则使用pyConnect（）建立连接。

还要确保在Python中安装了pattern.nlp包 - 请参阅http://www.clips.ua.ac.be/pattern
