需求：
構建 arm （linux_armv7l） 平臺上用於測試機器訓練的 python 鏡像，帶 numpy、 pandas、sklearn，等。
本文構建所用操作系統爲 ubuntu 16.04 64bit（4GB雙核），採用容器內安裝依賴庫的形式，非 Dockerfile，是因爲考慮到實際構建中可能會遇到各種問題。
技術總結
在 pc 端運行 arm 鏡像容器，使用arm32v7/python，此方式是爲了方便製作（也可在 arm 系統上直接製作）。
鏡像標籤爲 slim，其爲 Debian 的 buster 版本。容器中無法補齊命令，無法查看以往命令，使用較爲麻煩。
安裝編譯相關工具和庫，因爲有些 python 庫要本地編譯（據查，是沒有該平臺的預編譯包）。
安裝 numpy 等庫。注意，由於官方沒有現成的包，需要在本地編譯，故會較耗時。
pip 安裝會順帶安裝相應依賴包。
寫程序驗證（本文略）。
國內源是爲了加快下載速度。編譯耗時取決於機器性能。
知識點
在 x86 上運行 arm 容器。
從頭開始編譯、安裝 python 庫。
從容器變成鏡像。
實驗步驟
運行容器
建立 pc 端運行 arm 容器環境：
docker run --rm --privileged multiarch/qemu-user-static --reset -p yes
注：經測試發現，ubuntu 內核需在 4.8 以上。
運行基礎鏡像：
docker run -itd --name pythonslim arm32v7/python:3.7-slim sh
以下命令中，安裝、測試等在容器內進行。與 docker 有關的，在宿主機上進行。本文假定讀者能區別出來。
添加源
添加 debian 國內源，文件：
cat > /etc/apt/sources.list <<-EOF
deb http://mirrors.aliyun.com/debian/ buster main non-free contrib
deb-src http://mirrors.aliyun.com/debian/ buster main non-free contrib
deb http://mirrors.aliyun.com/debian-security buster/updates main
deb-src http://mirrors.aliyun.com/debian-security buster/updates main
deb http://mirrors.aliyun.com/debian/ buster-updates main non-free contrib
deb-src http://mirrors.aliyun.com/debian/ buster-updates main non-free contrib
deb http://mirrors.aliyun.com/debian/ buster-backports main non-free contrib
deb-src http://mirrors.aliyun.com/debian/ buster-backports main non-free contrib
EOF
原始內容爲：
# deb http://snapshot.debian.org/archive/debian/20200414T000000Z buster main
deb http://deb.debian.org/debian buster main
# deb http://snapshot.debian.org/archive/debian-security/20200414T000000Z buster/updates main
deb http://security.debian.org/debian-security buster/updates main
# deb http://snapshot.debian.org/archive/debian/20200414T000000Z buster-updates main
deb http://deb.debian.org/debian buster-updates main
添加 pip 國內源：
mkdir ~/.pip/
cat > ~/.pip/pip.conf <<-EOF
[global]
index-url = https://pypi.tuna.tsinghua.edu.cn/simple
[install]
trusted-host = https://pypi.tuna.tsinghua.edu.cn
EOF
注1：slim 版本沒有 vi 編輯器，故用此法。
注2：也可在 pip 安裝時用 -i 臨時指定源地址。
安裝編譯環境
apt-get install gcc g++ gfortran python-dev libopenblas-dev libblas-dev liblapack-dev cython -y
apt-get install libfreetype6-dev libpng-dev -y
apt-get install pkg-config -y # 注：需要此工具找freetype
apt-get install libfontconfig1-dev -y
安裝包
pip install numpy==1.18.1 -i https://pypi.tuna.tsinghua.edu.cn/simple
pip install pandas==0.23.4 -i https://pypi.tuna.tsinghua.edu.cn/simple
pip install scipy==1.4.1 -i https://pypi.tuna.tsinghua.edu.cn/simple
pip install Cython -i https://pypi.tuna.tsinghua.edu.cn/simple
pip install sklearn -i https://pypi.tuna.tsinghua.edu.cn/simple 注：依賴scipy Cython
pip install six -i https://pypi.tuna.tsinghua.edu.cn/simple
pip install xlrd -i https://pypi.tuna.tsinghua.edu.cn/simple
pip install pyparsing -i https://pypi.tuna.tsinghua.edu.cn/simple
pip install python-dateutil -i https://pypi.tuna.tsinghua.edu.cn/simple
pip install matplotlib==3.2.1 -i https://pypi.tuna.tsinghua.edu.cn/simple # 注：要freetype，先不安裝
pip install pyhht -i https://pypi.tuna.tsinghua.edu.cn/simple # 注：需要 scipy、matplotlib
注1：可用pip list查看安裝的庫及其版本。
注2：安裝（編譯） numpy、pandas、scipy、sklearn 等較耗時，每個包耗時數小時不等（因 slim 容器沒有 time 命令，無法知道具體耗時時間）。
查看安裝的包
本容器安裝的包：
# pip list

驗證
# python
import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
from sklearn import datasets,linear_model
如果沒有錯誤輸出，說明安裝成功。
製作鏡像
查看容器體積：
# du -h --max-depth=1
136M ./tmp
26M ./var
2.5M ./sbin
3.2M ./bin
220M ./root
1.5M ./etc
835M ./usr
7.1M ./lib
1.2G
將原始的容器保存爲鏡像：
docker commit pythonslim python-pandas-build:arm
這一步的目的是爲了保留編譯信息。方便後續製作。
清除不必要的文件：
apt-get autoremove python2 # bzip2 file會被刪除
apt-get autoremove gcc g++ gfortran # libgomp1 binutils binutils-arm-linux-gnueabihf 會被刪除
apt-get autoremove cython
apt-get autoremove perl
apt-get autoremove openssl
rm /usr/bin/perl /usr/bin/perl5.28.1
補回被刪除的包：
apt-get install libgomp1 # 注：sklearn依賴此包
apt-get install bzip2
清除緩存：
apt-get clean && rm -rf /var/lib/apt/lists/*
rm -rf /root/.cache
經分析，slim 版本的鏡像本身就超過 100 MB，加上 python 的幾個重要庫，經精簡後，體積仍近 600 MB。其中佔大頭的目錄是/usr/local/lib/python3.7/site-packages。
將精簡後的容器保存爲鏡像：
docker commit pythonslim python-pandas:arm
打標籤，提交(到筆者的阿里雲倉庫)：
docker tag python-pandas:arm registry.cn-hangzhou.aliyuncs.com/latelee/python-pandas:arm
docker push registry.cn-hangzhou.aliyuncs.com/latelee/python-pandas:arm
注：Docker 構建是分層的，不能在python-pandas-build:arm鏡像中精簡，因爲此鏡像已超 1 GB，即使刪除文件，Docker 鏡像亦舉減少。因此，需要在pythonslim中精簡。
運行：
docker run -itd --name pandas -v $PWD:/work registry.cn-hangzhou.aliyuncs.com/latelee/python-pandas:arm sh
問題及解決
安裝了 libfreetype6-dev 後，編譯 matplotlib 時還是提示 freetype 版本過低（即找不到庫），後添加 pkg-config ，可編譯通過。
使用
registry.cn-hangzhou.aliyuncs.com/latelee/python-pandas:arm爲公開鏡像（僅在當前可訪問，後續不保證）。安裝軟件需要執行apt-get update。
