xFormers
DESCRIPTION
xformers is a modular, performance-oriented library of transformer building blocks, designed to allow researchers and engineers to compose, experiment, and optimize transformer architectures more flexibly than monolithic frameworks. It abstracts components like attention layers, feedforward modules, normalization, and positional encoding, so you can mix and match or swap optimized kernels easily. One of its key goals is efficient attention: it supports dense, sparse, low-rank, and approximate attention mechanisms (e.g. FlashAttention, Linformer, Performer) via interchangeable modules. The library includes memory-efficient operator implementations in both Python and optimized C++/CUDA, ensuring that performance isn’t sacrificed for modularity. It also integrates with PyTorch seamlessly so you can drop in its blocks to existing models, replace default attention layers, or build new architectures from scratch. xformers includes training, deployment, and memory profiling tools.
Features
- Modular transformer building blocks (attention, FFN, norms, position encodings)
- Support for various efficient attention types (sparse, approximate, locality)
- Optimized GPU kernels and fallback Python implementations
- Seamless integration with PyTorch models and training loops
- Profiling and benchmarking tools to compare throughput, memory, and latency
- Support for mixing attention types in one model (hybrid architectures)
Programming Language
Python
