问题描述
我在遵循«开始于Rasa»教程
所以我输入了:
sudo pip3 install rasa-x --extra-index-url https://pypi.rasa.com/simple
这似乎工作正常，但是当我键入以下内容后:
which seems to work fine but when I’ve typed:
sudo rasa init
我当中有很多错误:
rasa.core.policies.ensemble.InvalidPolicyConfig: Module for policy ‘MemoizationPolicy’ could not be loaded. Please make sure the name is a valid policy.
推荐答案
当我尝试使用-rasa init时，我遇到了同样的问题.通过注意两件事可以解决此问题.当您尝试使用-pip安装rasa时，请在虚拟环境中安装rasa.这个安装了最新的python版本，在我的情况下是3.8，但是问题是TensorFlow支持3.8不可用，所以我建议-
I faced the same problem when I tried using - rasa init. This is solved by paying attention to 2 things. When you try to install rasa using - pip install rasa in a virtual environment. This install latest python version, in my case this was 3.8, but the problem was that TensorFlow support was not available for 3.8, So I will suggest-
conda create --name rasa python=3.6
对于anaconda或您也可以创建一个虚拟环境.现在使用
For anaconda or you could also create a virtual environment. Now use
pip install rasa
现在，您会注意到将安装TensorFlow == 1.15.1.为了使rasa正常工作，我们需要TensorFlow == 1.15.0
Now you will notice TensorFlow==1.15.1 will be installed. For rasa to work we will need TensorFlow==1.15.0
pip uninstall tensorflow
pip install tensorflow-cpu==1.15.0
如果您仅想获得CPU支持，
if you want CPU support only otherwise,
pip install tensorflow==1.15.0
这对我有用.
