Question

我想在docker中运行nltk服务。但是我总是收到错误消息＆＃34;＆＃39; nltk＆＃39;不是包裹＆＃34;。你能弄清楚出了什么问题吗？在构建期间一切正常，打印nltk版本。使用docker-compose up nltk启动容器时，我得到了

$ docker-compose up nltk

搬运工-compose.yml

nltk:
    build: docker/nltk
    container_name: nltk
    volumes:
      - ./volumes/nltk/var/www/nltk.py:/var/www/nltk.py
    environment:
      HOME: /var/www

Dockerfile

FROM python:3.6

RUN mkdir /var/www
ENV HOME /var/www
WORKDIR /var/www
RUN pip install -U nltk
RUN pip install -U numpy
RUN python -m nltk.downloader -d $HOME/nltk_data all
RUN python -c "import nltk"
RUN python -c "import nltk; print(nltk.__version__)"

EXPOSE 80

CMD [ "python", "/var/www/nltk.py" ]

nltk.py

import nltk
from nltk.corpus import brown

brown.words()

Answer 1

尝试将(odd? 3)重命名为其他内容。我猜测(cons 3 '())和nltk.py正在尝试从您的import nltk文件而不是包中导入。它在构建映像时的工作原因是因为您的from nltk.corpus文件尚不存在，因为它是在运行时从撰写文件中挂载的。

Answer 2

最终的Dockerfile

FROM python:3.6

ENV NLTK_DATA /usr/share/nltk_data

RUN pip install -U nltk
RUN pip install -U numpy
RUN python -m nltk.downloader -d /usr/share/nltk_data all

EXPOSE 80

WORKDIR /var/www

CMD [ "python", "/var/www/main.py" ]

最终的docker-compose

nltk:
    build: docker/nltk
    container_name: nltk
    volumes:
      - ./volumes/nltk/var/www/main.py:/var/www/main.py

NLTK不在码头工作
