错误“需要以下参数” --path-dataset-dir =

Question

我正在尝试将PATH_DATASET替换为提取的数据集的根文件夹，该根文件夹为C / Users / swarn / hand-on-music-generation-with-magenta / lmd_full / a。但它显示错误为：

chapter_06_example_00.py：错误：需要以下参数：--path_dataset_dir = C / Users / swarn /带洋红色的音乐生成/ lmd_full / a，-path_output_dir / C / Users / swarn /带有洋红色的音乐生成手--bass_drums_on_beat_threshold = 0.75 发生异常，请使用％tb查看完整的追溯。

我对输入数据根文件夹的位置有错吗？

我来自github的部分代码：
