- * @brief Class that uses data from external memory that is not managed by a backend
- *        instead of allocating and copying the data. ExternalTensor's data pointer points to
- *        an address of memory such as where memory is already allocated, or mmapped area.
- *        This is meaning that ExternalTensor can take all of types' ir::Data.
- *        To support this, assume below things no padding, always NHWC layout,
- *        constant tensor and not dynamic.
