Profiling in PyTorch (Part 2): From nn.Linear to a Fused MLP
The Hugging Face blog details optimizing PyTorch performance by fusing MLP layers. Fusing nn.Linear layers into a single kernel improves inference speed and reduces memory usage. This technique can be applied to other PyTorch modules for similar performance gains. Builders can use these optimizations to deploy models more efficiently.
Key takeaways
- Fusing nn.Linear layers improves inference speed.
- Reduces memory usage.
- Optimization technique applicable to other PyTorch modules.
