【きれい】RGB色空間の断面図アニメーションをPython+matplotlib+ffmpegで作成した
https://qiita.com/yamasaki1ma/items/d3a691d69260b7b96f46

Pythonのバージョンは3.6.6、matplotlibのバージョンは2.2.2。

をdockerで実行しようとした。

<この項は書きかけです。順次追記します。>

環境

docker:ubuntu
Python 3.10.1 (main, Dec 8 2021, 03:30:49) [GCC 10.2.1 20210110] on linux
pip version 21.3.1
matplotlib-3.5.1

bash

$ docker run -it python /bin/bash

pythonのdockerが起動したら。

bash

# apt update; apt -y upgrade
# python -m pip install --upgrade pip
# pip install matplotlib
# apt install -y ffmpeg vim
# vi yama.py

実行。６分たっても終わらない。CTRL+Cで中断してみた。

bash

# python --version
Python 3.10.1
# python yama.py

あ、１００個ちょいで６分かかるなら、２５６個作るのは１５分はかかるはず。次は少し待ってみる。

bash

# vi yama.sh
# chmod 0777 yama.sh

# ./yama.sh

１回目と２回目であまり差はない。
測定用のシェル記述　yama.shは

yama.sh

２回目
Sun Dec 12 14:08:50 UTC 2021

1回目８分で処理したらしい。２回目はなぜか９分３０秒かかっている。

動画をYoutubeに上げました。

一部意図通りでないようなところがあるかもしれません。
どうしたらいいか、順次調べたい。

docker hubに登録しました。
/home/yama
にファイルは保存してあります。

bash

$ docker commit ce24d790d857  kaizenjapan/pythonffmpeg
$ docker push kaizenjapan/pythonffmpeg
The push refers to repository [docker.io/kaizenjapan/pythonffmpeg]
---

ご自身の機材で動画を見たい場合には、もし、/tmp/yamaが空であれば、

```macOS:bash
$ docker run -v /tmp/yama:/tmp/yama -it  kaizenjapan/pythonffmpeg /bin/bash

と起動していただくと、/home/yamaから/tmp/yamaに必要なファイルを複写すれば、端末のソフトでも閲覧できます。

失敗例

最初の作業は手順がちぐはぐだった。やり直したのが上記。

2025年２月末を目標にしている。
