Inferenza Efficiente su CPU

Questa guida si concentra sull'inferenza di modelli di grandi dimensioni in modo efficiente sulla CPU.

PyTorch JIT-mode (TorchScript)

TorchScript è un modo di creare modelli serializzabili e ottimizzabili da codice PyTorch. Ogni programma TorchScript può esere salvato da un processo Python e caricato in un processo dove non ci sono dipendenze Python. Comparandolo con l'eager mode di default, jit mode in PyTorch normalmente fornisce prestazioni migliori per l'inferenza del modello da parte di metodologie di ottimizzazione come la operator fusion.

Per una prima introduzione a TorchScript, vedi la Introduction to PyTorch TorchScript tutorial.

IPEX Graph Optimization con JIT-mode

Intel® Extension per PyTorch fornnisce ulteriori ottimizzazioni in jit mode per i modelli della serie Transformers. Consigliamo vivamente agli utenti di usufruire dei vantaggi di Intel® Extension per PyTorch con jit mode. Alcuni operator patterns usati fequentemente dai modelli Transformers models sono già supportati in Intel® Extension per PyTorch con jit mode fusions. Questi fusion patterns come Multi-head-attention fusion, Concat Linear, Linear+Add, Linear+Gelu, Add+LayerNorm fusion and etc. sono abilitati e hanno buone performance. I benefici della fusion è fornito agli utenti in modo trasparente. In base alle analisi, il ~70% dei problemi più popolari in NLP question-answering, text-classification, and token-classification possono avere benefici sulle performance grazie ai fusion patterns sia per Float32 precision che per BFloat16 Mixed precision.

Vedi maggiori informazioni per IPEX Graph Optimization.
