无法安装scipy

Question

我正试图从Dockerfile安装scipy，我不能为我的生活弄清楚如何。

这里是Dockerfile：

FROM python:3.5 

ENV HOME /root 

# Install dependencies 
RUN apt-get update 
RUN apt-get install -y gcc 
RUN apt-get install -y build-essential 
RUN apt-get install -y zlib1g-dev 
RUN apt-get install -y wget 
RUN apt-get install -y unzip 
RUN apt-get install -y cmake 
RUN apt-get install -y python3-dev 
RUN apt-get install -y gfortran 
RUN apt-get install -y python-numpy 
RUN apt-get install -y python-matplotlib 
RUN apt-get install -y ipython 
RUN apt-get install -y ipython-notebook 
RUN apt-get install -y python-pandas 
RUN apt-get install -y python-sympy 
RUN apt-get install -y python-nose 

# Install Python packages 
RUN pip install --upgrade pip 
RUN pip install cython 

# Install scipy 
RUN apt-get install -y python-scipy 

这将构建一个图像，但是当我运行的容器，并尝试import scipy它说：使用RUN pip install scipy和RUN pip install git+https://github.com/scipy/scipy.git但这些

Python 3.5.1 (default, Mar 9 2016, 03:30:07) 
[GCC 4.9.2] on linux 
Type "help", "copyright", "credits" or "license" for more information. 
>>> import scipy 
Traceback (most recent call last): 
    File "<stdin>", line 1, in <module> 
ImportError: No module named 'scipy' 

我曾尝试在完成构建之前抛出一个错误。

您正在使用Python 3，但安装了Python 2包。将您的Dockerfile更改为以下内容：

FROM python:3.5 

ENV HOME /root 
ENV PYTHONPATH "/usr/lib/python3/dist-packages:/usr/local/lib/python3.5/site-packages" 

# Install dependencies 
RUN apt-get update \ 
    && apt-get upgrade -y \ 
    && apt-get autoremove -y \ 
    && apt-get install -y \ 
     gcc \ 
     build-essential \ 
     zlib1g-dev \ 
     wget \ 
     unzip \ 
     cmake \ 
     python3-dev \ 
     gfortran \ 
     libblas-dev \ 
     liblapack-dev \ 
     libatlas-base-dev \ 
    && apt-get clean 

# Install Python packages 
RUN pip install --upgrade pip \ 
    && pip install \ 
     ipython[all] \ 
     numpy \ 
     nose \ 
     matplotlib \ 
     pandas \ 
     scipy \ 
     sympy \ 
     cython \ 
    && rm -fr /root/.cache
