on_iteration_start

FileLogger.on_iteration_start(iteration: int, params: ndarray, **kwargs) → None

No-op; iteration starts are intentionally silent.

on_iteration_end already records the result of the iteration, and per-eval rows provide finer-grained progress, so emitting an extra row at the start of each iteration would only add noise.

Parameters:

iterationint

Current iteration number (unused).

paramsnp.ndarray

Parameter vector at iteration start (unused).

**kwargs

Additional keyword arguments (unused).
