概要

2020年に発表された論文Dancing To Musicのソースコードを試してみました
https://github.com/NVlabs/Dancing2Music

モジュールのバージョンが一切公開されていなかったので、動作する組み合わせを調べるのに大変時間がかかりました。バージョンを明記したrequirement.txtも同時に公開してほしいものです。今回はデモを動かすところまで動作確認できました。学習までは試していません。

環境の準備

requirement.txtはこんな感じで。私はローカルのubuntu18.04環境(GTX1080Ti)のdocker上で実行しています。以下のモジュールに加えて、Pythonは3.6.3でデモの動作確認できました。Python3.6.0では動かないので注意。

numpy==1.18.5
matplotlib
torch==1.7.0
torchvision==0.8.1
librosa==0.8.0
jupyter==1.0.0
opencv-python==4.4.0
tensorflow==2.3.1

ffmpegも必要です。

apt install ffmpeg

データとモデルのダウンロード

かなりわかりにくいですがreadme.mdのProjectのところにリンクがあります
http://vllab.ucmerced.edu/hylee/Dancing2Music/script.txt

## Dataset
### Content
#### 3 zip files containing data of three dancing categories: Zumba, ballet, and hiphop.
####1 zip files containing data statistics and data path lists for trainint usage.

URL=http://vllab.ucmerced.edu/hylee/Dancing2Music/ballet.zip
wget -N $URL -O ./ballet.zip
unzip ./ballet.zip -d .
rm ./ballet.zip

...（以下略）

こちらをシェルで実行するとダウンロードが開始されます

ソースコードのダウンロードと実行

こちらからgit cloneしたソースではファイルが足りないので動きません！
https://github.com/NVlabs/Dancing2Music

著者が自分のページで公開しているものをダウンロードします（これはひどい）
http://vllab.ucmerced.edu/hylee/Dancing2Music/demo.zip

demoフォルダの中にcheckpointフォルダを作って、ダウンロードしたチェックポイントのファイルを入れます

%mkdir demo/checkpoint
%cp Stage1.ckpt demo/checkpoint
%cp Stage2.ckpt demo/checkpoint

demo.pyを実行します。aud_pathに入力音声ファイルを指定します。--out_fileに出力するダンスの動画ファイル名を指定します。２つ目のチェックポイントは--resumeで指定します（githubのドキュメントと違うので注意）

%Dancing2Music/demo# cat demo.sh
python demo.py --decomp_snapshot checkpoint/Stage1.ckpt --resume checkpoint/Stage2.ckpt --aud_path demo/ChillingMusic.wav --out_file demo/output.mp4 --out_dir demo/out_frame

うまくいけば以下のような表示の後でoutput.mp4が出力されます。

%sh demo.sh

実行結果

こんな感じの動画が出力されます（Qiitaの都合でgifにしていますが実際にはmp4で音が出ます）

音と合っているかといわれると、合っているようにも見えますが、微妙なところです。やはりこの手の論文は実際に動かしてみるに限りますね
