设置我们的Rasa/NLU容器，错误？

Question

我有这个文件Dockerfile.nlu

FROM chatbot/spacy:latest
WORKDIR /app
COPY nlu ./agent_nlu
RUN python –m rasa_nlu.train --config agent_nlu/config.yml --data agent_nlu/data/ --path agent_nlu/agent --fixed_model_name default

我得到了下面的错误：

]$ sudo docker build -t nlu:latest -f docker/Dockerfile.nlu .
Sending build context to Docker daemon  9.216kB
Step 1/4 : FROM chatbot/spacy:latest

Answer 1

看起来Docker找不到nlu目录。你确定它存在吗？您确定正在从正确的目录执行命令吗？

但您也根本没有安装Rasa或它的任何要求。您没有使用预先构建的Rasa镜像有什么原因吗？随docs here提供的here。

这是一个从他们的repo中拉出的功能齐全的Docker文件。
