.sh内で.pyを実行するときの引数指定が通らない

Question

前提・実現したいこと

これを実行すると「python3 GenFeature.py $DATASET $D_PATH --phase $PHASE --piece-per-file $PIECE_PER_FILE --save-path $OUTPUT」のところで、D_PATHが指定されてないとのエラーがでます。
なにがおかしいのでしょうか。

#!/bin/bash

DATASET=MusicNet
D_PATH=/mnt/Users/Owner/Documents/wsl-music-recommendation-venv/Music-Transcription-with-Semantic-Segmentation-master/musicnet.tar.gz
PHASE=train
PIECE_PER_FILE=40
OUTPUT=/mnt/Users/Owner/Documents/wsl-music-recommendation-venv/Music-Transcription-with-Semantic-Segmentation-master/${PHASE}_feature

cd ..
python3 GenFeature.py $DATASET $D_PATH --phase $PHASE --piece-per-file $PIECE_PER_FILE --save-path $OUTPUT

エラーを見る限り、問題はif name == "main"のところだけ見れば良さそうですが念のため全部のせときます

Answer 1

parser.add_argument("dataset-path", help="Path to the downloaded dataset",
                        type=str)

において、マイナス記号を含んだ"dataset-path"というキーワードを使用していることが原因です。
