Resolve conflicts file

Hi,
I'm trying to use pygit2 to resolve repo conflicts.
I intentionally created a conflict between a file in the local repo and a file in the remote repo. I have seen on certain methods that the favorite argument exists to have ours or theirs but I do not understand how to implement it, I always have "cannot create a tree from a not fully merged index" when I do my self .repo.index.write_tree()

从 pygit2 的冲突解决 API 以及报告中描述的 repo.index.write_tree() 调用开始。重现有意冲突的本地文件和远程文件，然后确定在写入树之前应如何应用 favorite 参数。完成的标准是记录或修正受支持的 ours/theirs 工作流，使 index 能够在不出现所报告错误的情况下写入。
