Accelerate removes much of the device-parallelism work from machine-learning code, letting practitioners focus on training and inference across multiple GPUs. section 5.1.2
Its practical profile includes:
- Adds only one import and two lines of code for parallelizing and scaling workloads. section 5.1.2
- Supports both training and inference, with automation, compiling, and parallelization. section 5.1.2
- Fits alongside packages such as DeepSpeed, BitsandBytes, and xFormers, although combined features are experimental. section 5.1.2
