关于songmass使用旋律生成歌词的疑问

首先非常感谢各位能开源这么好的工具！
我尝试了一下songmass的旋律生成歌词的功能.没有找到可以直接给一段旋律，然后生成歌词的方案。我现在的操作流程是.
制作旋律的文件和歌词文件，然后把他们当做验证集，使用验证集的方式来出结果.
具体流程如下:
fairseq-preprocess \ --user-dir mass \ --task xmasked_seq2seq \ --source-lang lyric --target-lang melody \ --trainpref $para_data_dir/train --validpref $para_data_dir/t3 \ --destdir $save_dir \ --srcdict $para_data_dir/dict.lyric.txt \ --tgtdict $para_data_dir/dict.melody.txt bash infer_lyric.sh $data_dir mass $model
问题是:

1. 请问有办法直接给一个旋律自动生成歌词么?
2. 我使用测试集和验证集里的数据，推理出的结果表现都很完美，和参考的的完全一致，所以请问测试集和验证集都参与过训练是么?
3. 我自己按照规则制作了一首歌曲，推理出的结果很差。
   我自己制作的歌词和旋律如下:

旋律:
65 129 65 129 [align] 65 129 72 129 [align] 72 129 67 130 [align] [sep] 67 129 [align] 67 129 67 129 [align] 67 129 65 129 [align] 64 129 65 129 [align] [sep] 65 129 65 129 [align] 65 129 65 129 [align] 65 129 [align] 65 129 65 129 [align] [sep] 65 129 [align] 65 129 [align] 65 129 [align] [sep] 72 130 [align] 65 129 [align] 65 129 [align] [sep]

歌词:
sky [align] is [align] raining [align] [sep] i [align] want [align] stay [align] alone [align] [sep] stay [align] with [align] my [align] mama [align] [sep] one [align] two [align] three [align] [sep] let [align] is [align] go [align] [sep]

Start with the mentioned fairseq-preprocess command and infer_lyric.sh entry point. Determine whether the existing workflow accepts melody-only input, how training, validation, and test splits are used, and what preprocessing assumptions affect the custom example. Done means documenting clear answers and any supported usage or data-split limitations.
