在Dockerfile中安装 pandas [英] Install pandas in a Dockerfile

问题描述

我正在尝试创建Docker映像. Dockerfile如下:

I am trying to create a Docker image. The Dockerfile is the following:

# Use the official Python 3.6.5 image
FROM python:3.6.5-alpine3.7

# Set the working directory to /app
WORKDIR /app

# Get the 
COPY requirements.txt /app
RUN pip3 install --no-cache-dir -r requirements.txt

# Configuring access to Jupyter
RUN mkdir /notebooks
RUN jupyter notebook --no-browser --ip 0.0.0.0 --port 8888 /notebooks

Requirements.txt文件为:

The requirements.txt file is:

jupyter
numpy==1.14.3
pandas==0.23.0rc2
scipy==1.0.1
scikit-learn==0.19.1
pillow==5.1.1
matplotlib==2.2.2
seaborn==0.8.1

当docker尝试安装熊猫时，运行命令docker build -t standard .给我一个错误. 错误如下:

Running the command docker build -t standard . gives me an error when docker it trying to install pandas. The error is the following:

Collecting pandas==0.23.0rc2 (from -r requirements.txt (line 3))

当我尝试安装较低版本的pandas == 0.22.0时，出现此错误:

When I try to install a lower version of pandas==0.22.0, I get this error:

我还尝试在熊猫之前安装Cyphon和setuptools，但在pip3安装熊猫行中却出现了相同的No matching distribution found for Cython错误.

I also tried to install Cyphon and setuptools before pandas, but it gave the same No matching distribution found for Cython error at the pip3 install pandas line.

如何安装熊猫.

推荐答案

我现在可以创建Docker映像. FROM python:3.6.5-alpine3.7和熊猫之间肯定存在某些版本不兼容. 我将Python版本更改为FROM python:3，然后运行良好(还必须将pillow版本降级为5.1.0).

I could create the Docker image now. There must have been some version incompatibilities between FROM python:3.6.5-alpine3.7 and pandas. I changed the Python version to FROM python:3, then it worked fine (also had to downgrade the pillow version to 5.1.0).
