DockerSkeleton python ML模块安装错误

Question

我正在尝试通过 dockerSkeleton 安装 python ml 模块，以便我可以从 openwhisk cli 调用 docker 操作，但我不断遇到错误并且找不到太多帮助。

  `setup.py clean` is not supported, use one of the following instead:

    - `git clean -xdf` (cleans all files)
    - `git clean -Xdf` (cleans all versioned files, doesn't touch
                        files that aren't checked into the git repo)

  Add `--force` to your command to use it anyway if you must (unsupported).

我用来构建它的 docker 文件是

# Dockerfile for Python whisk docker action
FROM openwhisk/dockerskeleton

ENV FLASK_PROXY_PORT 8080


# lapack-dev is available in community repo.
RUN echo "http://dl-4.alpinelinux.org/alpine/edge/community" >> /etc/apk/repositories

# add package build dependencies
RUN apk add --no-cache \
        g++ \
        lapack-dev \
        gfortran


# Install our action's Python dependencies
ADD requirements.txt /action/requirements.txt
RUN cd /action; pip install -r requirements.txt

# Add all source assets
ADD . /action
# Rename our executable Python action

ADD main.py /action/exec


CMD ["/bin/bash", "-c", "cd actionProxy && python -u actionproxy.py"]

需求文件是

numpy==1.14.3
elm
scipy
sklearn

我搜索了很多网站，但没有任何帮助，如果有人对 openwhisk docker python 操作有任何想法或经验，请提供任何帮助。

我已经通过安装 numpy 进行了检查，并且它工作正常，但是当我同时添加 scipy 和 numpy 来安装它时，我会抛出找不到 numpy 模块的错误。

谢谢

Answer 1

尝试使用 python 运行时类型python-jessie:3 它已经包含一些与机器学习相关的包，例如 numpy、scipy、pandas 和 scikit-learn

例如使用 CLI 创建操作

ibmcloud fn action update mymlaction mymlaction.py --kind python-jessie:3
