无法加载模型，从坞-组合中错误初始化DIETClassifier图

Question

https://github.com/RasaHQ/rasa/blob/main/docker/docker-compose.yml i不能使用docker-组合加载我的模型，它为节点'run_DIET‘提供了一个初始化图组件。

version: '3.0'

services:
  rasa:
    image: rasa/rasa:3.0.8-full
    networks: ['rasa-network']
    ports:
    - "5005:5005"
    volumes:
    - "./formbot/:/app/"
    environment:
      MPLCONFIGDIR: "/tmp/"
    command:
    - run
    - --enable-api  
    - --cors   
    - "*"  

  action_server:
    image: rasa/rasa-sdk:latest
    networks: ['rasa-network']
    ports:
    - "5055:5055"
    volumes:
    - "./formbot/actions:/app/actions"

  duckling:
    image: rasa/duckling:latest
    networks: ['rasa-network']
    ports:
    - "8000:8000"

networks: {rasa-network: {}}

这是原木

Answer 1

可能的问题是模型文件将引用来自/tmp的组件依赖项。并在预置容器(rasa/rasa:3.0.8-满容器)修补时导致模型变坏。

作为一种解决方法，我们可以在将workdir克隆到预先构建的容器中完全训练模型，这些容器生成一个完全满足所有依赖项的新模型。

添加停靠文件

FROM rasa/rasa:3.0.6-full

RUN rasa init --no-prompt
USER root
WORKDIR /app
COPY . .

RUN rasa train
RUN chmod +x /app/scripts/*

ENTRYPOINT []

CMD /app/scripts/start_services.sh

和脚本/start_services.sh

rasa run --model /app/models --enable-api --cors "*" --debug \
        --endpoints /app/endpoints.yml \
        -p 8080
