 **Windows + Python 3.11/3.12** 環境では、`datasets` ライブラリが `multiprocessing` の `RLock._recursion_count` エラーを引き起こすことがあります（Python 側の未修正バグ）。
 
-**回避方法：pandas で直接読む（推奨）**
+**回避方法1：load_dataset をバイパス（推奨）**
 ```python
 import pandas as pd
 
 url = "https://huggingface.co/datasets/yeeko/Elaina_WanderingWitch_audio_JA/resolve/main/train/metadata.parquet"
-df = pd.read_parquet(url)
+df = pd.read_parquet(url)  # pandas 直接読込、multiprocess なし
