struct TensorObject#

Handle for interacting with Morpheus Tensor objects. Typically constructed using the Tensor::create factory method.

inline TensorObject &swap(TensorObject &&other) noexcept#

Explicitly swap the pointers to the underlying data with another tensor. Use inplace of the move operator since it’s hard to determine when you want to perform a move vs copy the data.

Returns:

TensorObject&

inline std::shared_ptr<MemoryDescriptor> get_memory() const#
inline std::string get_numpy_typestr() const#
inline TensorObject as_type(DType dtype) const#
inline TensorObject copy_rows(
const std::vector<RangeType> &selected_rows,
TensorIndex num_rows
) const#

Creates a deep copy of the rows specified in the exclusive ranges of vector<pair<start, stop>> of the stop row.

Parameters:

  • selected_rows –

  • num_rows –

Returns:

TensorObject

Friends

inline friend void swap(
TensorObject &lhs,
TensorObject &rhs
) noexcept#

Swap this tensor with another. Only the pointers to the enderlying data are exchanged. No values are moved.
