netket.vqs.local_estimators#

netket.vqs.local_estimators(vstate, op, chunk_size)[source]#

Compute per-sample local estimator data for operator op on vstate.

Returns a LocalEstimators (scalar, data shape (n_chains, chain_len)) or a LocalEstimatorsBatch (K-channel, data shape (n_chains, chain_len, K)).

The default dispatch uses get_local_kernel_arguments + get_local_kernel and returns a scalar LocalEstimators. Override this for operators that do not fit the kernel pattern (e.g. variance, infidelity).

Parameters:

  • vstate (Any)

  • op (Any)

  • chunk_size (int | None)
