cuquantum.bindings.cutensornet.state_update_tensor_operator_gradient(
intptr_t handle,
intptr_t tensor_network_state,
int64_t tensor_id,
intptr_t gradient_data,
)[source]#

Updates the gradient output buffer for a tensor operator that was previously applied with gradient.

Parameters:

  • handle (intptr_t) – cuTensorNet library handle.

  • tensor_network_state (intptr_t) – Tensor network state.

  • tensor_id (int64_t) – Tensor id assigned during the state_apply_tensor_operator_with_gradient() call.

  • gradient_data (intptr_t) – Device-accessible pointer for gradient output.
