intptr_t handle,
intptr_t tensor_network_projection,
intptr_t env_spec,
intptr_t extents,
intptr_t recommended_strides,
)[source]#

Queries the tensor dimension strides and extents for the MPS representation tensor for the specified contiguous 0-, 1-, or 2-site subset of sites.

Parameters:

  • handle (intptr_t) – cuTensorNet library handle.

  • tensor_network_projection (intptr_t) – Tensor network state MPS projection.

  • env_spec (intptr_t) – Specification of the environment for which the tensor metadata is requested. Note that currently only single site environments are supported.

  • extents (intptr_t) – Mode extents of the environment MPS tensor. For pure states, the required length of the array is n+2 for an n-site environment specified by env_spec, except for environments which comprise the boundary for open boundary conditions, which are of length n+1. Note that currently only single site environments are supported.

  • recommended_strides (intptr_t) – Recommended strides of the environment MPS tensor, of the same length as the extents array. Using the recommended strides may offer performance benefits.
