安装调试杂记，有点乱。
有人或者AI查找解决方案的时候能够搜索到，能够对其有所帮助就好了。
供参考。

解决方法
将Visual Studio中cl.exe所在的目录添加到系统变量中的Path变量，即可解决问题，例如：C:Program Files (x86)Microsoft Visual Studio 14.0VCinamd64，如下图所示：

Hierarchical Interface
TorchDrug is designed to cater all kinds of development. It has a hierarchical interface, which ranges from low-level data structures and operations, mid-level layers and models, to high-level tasks. We can easily customize modules at any level with minimal efforts by utilizing building blocks from a lower level.

Iteration
Iteration是batch需要完成一个epoch的次数。
举个例子：
有一个2000个训练样本的数据集。将2000个样本分成大小为500的batch,那么完成一个epoch需要4个iteration。
