module 'scvi' has no attribute 'model' ​

这个错误信息表示你在Python中尝试访问'scvi'模块中的'模型'(model)属性或函数，但是该模块实际上并没有提供名为'model'的属性。`scvi`是一个单细胞测序数据分析库（Single Cell Variational Inference），它可能包含多种类或函数，但直接查找'model'可能会导致找不到对应的对象。

通常，解决这个问题需要检查以下几个步骤：
1. 确认你的`sampling`是否拼写错误，可能是`ScVIModel`而不是`model`。
2. 检查你的`sampling`对象是否已经正确初始化并加载了数据。
3. 查看官方文档或GitHub仓库确认`scvi`当前版本是否有'model'这个属性，如果没有，可能需要更新到支持该功能的版本，或者使用其他提供的替代方案。

2. 检查你的代码中是否存在拼写错误或语法错误。
3. 确认你的scvi库已经正确安装并且版本正确。
4. 如果以上步骤都没有解决问题，你可以查看scvi.model模块的源代码，确认是否存在名为LDVAE的属性。
