fms-acceleration-peft 0.0.1

FMS Acceleration for PeFT

FMS Acceleration for Accelerated PeFT Techniques

Currently only supports LoRA-related techniques, but more are in the pipeline to be added:

Plugins

Plugin	Description	Depends	Loading	Augmentation	Callbacks
autogptq	Loads 4bit GPTQ-LoRA with quantized GPTQ as base	AutoGPTQ	✅	✅
bnb	Loads 4bit QLoRA with quantized bitsandbytes Linear4	Huggingface bitsandbytes	✅	✅

Key Points

• fix upcasting (resulting in slowdown) issue for bnb plugin, originally discovered by inventors of Unsloth.
• bnb properly configured to work with FSDP following this guide.
• triton_v2 kernels are not yet properly integrated into huggingface optimum.
• triton_v2 kernels are the only 4bit kernels that work for training.

Known Issues

• Models with sliding windows (e.g., Mistral, Mixtral) will have memory and throughout issues.
• GPTQ-LORA sometimes observed to have nan grad norms in the begining of training, but training proceeds well otherwise.
• low_cpu_mem_usage temporarily disabled for AutoGPTQ until bug with make_sure_no_tensor_in_meta_device is resolved.
• Requires nightly AutoGPTQ until package > 0.7.1 becomes available
