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 action，但是我一直处于错误状态，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).

和我用来构建它的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
我已经搜索了很多网站，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。
我已经通过仅安装numpy进行了检查，它可以正常工作，但是以某种方式在我同时添加scipy和numpy时都安装了它，这引发了我找不到numpy模块的错误。
谢谢

尝试使用python运行时类型python-jessie:3，它已经包含一些与ML相关的软件包，例如numpy，scipy，pandas和scikit-learn
例如，使用CLI创建动作
ibmcloud fn action update mymlaction mymlaction.py --kind python-jessie:3
