我尝试使用 RASA 来构建一个示例机器人，但我收到了错误消息，

我用 ：
PYTHON 3.6.0
RASA CORE 0.12.0
RASA NLU 0.13.0
TENSORFLOW 1.10.0
PROTOBUF 3.6.0
有可能解决这个问题吗？谢谢
对于 rasa_core 版本，0.12您必须为培训提供策略配置。例如，您可以从Github为该模板设置默认模板。例如，将以下代码段保存在名为 的文件中default_config.yml：
policies:
- name: KerasPolicy
epochs: 100
max_history: 5
- name: FallbackPolicy
fallback_action_name: 'action_default_fallback'
- name: MemoizationPolicy
max_history: 5
- name: FormPolicy
然后使用以下命令训练 Rasa Core：
python -m rasa_core.train \
-d <path to domain file> \
-s <path to stories> \
-c default_config.yml \
-o models/dialogue
然后运行训练好的模型：
python -m rasa_core.run -d models/dialogue
