解决pip install rasa==3.0.8无动于衷的问题
我的安装环境是win10，minconda，Python3.8.12
在conda中创建了一个名为rasa_3.0的环境【命令：conda create -n rasa_3.0 python==3.8.12】当我使用pip install rasa==3.0.8的时候，刚开始速度还挺快，后面就卡在那里一动不动，以为是网络和本地pip依赖的问题，就索性让他一直在那安装，等到第二天早上还是泪崩了，因为一直没成功，陷入了无限循环，如下面的一段code。

于是google搜索了一番，发现可以解决问题，记录一下下。
网上有说，如果安装过tensorflow，要卸载掉tensorflow，但我的环境没有。
我使用了下面的命令安装，一下下就好了。欣喜若狂
pip3 install -U --user pip && pip3 install rasa -i https://pypi.org/simple
这个命令如果没有科学上网，要多试几遍，毕竟链接外网。我在服务器上就是试了多几遍才成功的。
屏幕出现了如下的信息，代表大功告成。

纯属记录篇，因为rasa变化还是挺快的，当前时间又是安装最新的版本，难免踩坑掉坑爬坑。
