§parallel_execution: bool

グラフ内の並列実行モード (false で Sequential、true で Parallel)。

§optimization_level: OptimizationLevel

グラフ最適化レベル。

§enable_mem_arena: bool

CPU メモリアリーナの有効化。

§pool_size: usize

並行推論用セッションプールサイズ (デフォルト: 1)。

§optimized_model_path: Option<PathBuf>

最適化済みモデルグラフのディスク保存・キャッシュパス (任意)。

Implementations§

Source§

impl SessionConfig

Source

pub fn auto() -> Self
