- * This is a minimal Tensor class for use in c10 code.
- * The plan on record is to eventually merge at::Tensor and caffe2::Tensor
- * and move that merged class to c10, replacing this one.
- *
- * At time of writing this, we couldn't do that yet, because their APIs are
- * not clean enough to make it in c10 and because they have dependencies we want
- * to avoid, for example at::Tensor depends on at::Type.
