cuquantum.cutensornet.create_contraction_optimizer_info_from_packed_data¶

cuquantum.cutensornet.create_contraction_optimizer_info_from_packed_data(intptr_t handle, intptr_t tn_desc, buf, size_t size) → intptr_t[source]¶

Create a contraction optimizer info object from the packed data.

Parameters

handle (intptr_t) – The library handle.
tn_desc (intptr_t) – The tensor network descriptor.
buf –
A contiguous host buffer holding the packed optimizer info. It can be
- an int as the pointer address to the buffer
- any Python object supporting the Python buffer protocol. In this case, it must be 1D and writable; the format would be ignored.
size (size_t) – The buffer size in bytes.

Returns

An opaque optimizer info handle (as Python int).

Return type

intptr_t
