test rasa nlu时报错builtins.ValueError: bad input shape (1, 13)

[jinyang10014]

你好，我按照Readme.md一步步搭建环境，做到"test rasa nlu"这一步时遇到解决不掉的问题，执行【python httpserver.py】可以正常启动，新开窗口执行curl命令后，httpserver端报错“Unhandled Error”、“builtins.ValueError: bad input shape (1, 13)”，这里不会解决了，请问这个是什么情况啊，需要如何解决？我的操作系统是CentOS 6.3。

确认下rasa版本试试：rasa_core==0.9.0

我也遇到这个问题，rasa版本是对的， python3.5。报错信息：

不知道如何解决？挺着急的。。。

[Ted-Yee]

scikit-learn：0.19.1

[zhangrenjie666666]

@Ted-Yee 请问你是怎么解决的

[Chenny0808]

@nihuizhidao scikit-learn 要为0.19.2，我修改sklearn版本后就好了
