Release notes

Sourced from accelerate's releases.

v1.14.0: AMD ROCm support, FSDP2 hardening

FSDP2 Improvements

This release brings a large batch of FSDP2 fixes and quality-of-life improvements: correct dtype handling on load, sharding of embeddings/norms, QLoRA crash prevention, and a more robust auto-wrap policy.

• Fsdp2 fully_shard embedding and norm by @​SunMarc in #4015
• Fix fsdp2 load full state dict dtype mismatch by @​SunMarc in #4021
• Fix region compilation fsdpv2 by @​SunMarc in #4022
• [FSDP2] Cast model to uniform dtype before fully_shard to fix mixed-dtype AssertionError by @​roycho96 in #3985
• [FSDP2] Auto-exclude non-floating frozen Params4bit from fully_shard to prevent QLoRA crash by @​roycho96 in #3987
• fix(FSDP2): auto-wrap policy ignoring _no_split_modules fallback by @​JohnGiorgi in #3999
• fix: use key-based matching in fsdp2_load_full_state_dict by @​roycho96 in #3982
• fix: add missing model_has_params4bit guard to fsdp2_load_full_state_dict call by @​roycho96 in #3981
• Fix to-fsdp2: drop REMOVED / NOT_YET_IMPLEMENTED FSDP1 keys instead of leaking them by @​lollinng in #4065
• Prevent double-wrapping models in prepare_model() by @​joshuaswanson in #3977

AMD ROCm support

Accelerate now works end-to-end on AMD ROCm devices. Thanks @​Abdennacer-Badaoui!

• Make accelerate work end-to-end on AMD ROCm by @​Abdennacer-Badaoui in #4025

Neuron

Further Neuron improvements to reduce recompilation and cover missing device cases.

• Add padded allgather and broadcast for Neuron devices to reduce recompilation by @​czkkkkkk in #4000
• fix: add missing neuron device case by @​michaelbenayoun in #4042

Quantization & Offloading

We improved offloading support for quantized models, including Torchao, int8, and tied-weight handling.

• Torchao offload by @​SunMarc in #3973
• Fix int8 offload hook detachment statistics restoration by @​jiqing-feng in #4044
• Fix keep_in_fp32_modules not working for tied weights in load_and_quantize_model by @​jiqing-feng in #4043
• Fix dtype_byte_size for FP8 fnuz / e8m0fnu dtypes by @​lollinng in #4063

Data Loading

• Feat: Support dynamic batch size in BatchSamplerShard with even_batches by @​yuxinyuan in #3969
• Fix iterable dataset sharding condition when n_shards == num_processes by @​SunMarc in #3958
• Fix implicit padding in split_between_processes when apply_padding=False and num_samples < num_processes by @​3manifold in #4052

Minor fixes

• [DeepSpeed] allow kernels flash-attn in SP by @​kashif in #3959
• Fix: Conditionally import torch.distributed.algorithms.join in accelerator.py by @​0xDELUXA in #3962
• Fix is_hf_initialized attribute by @​SunMarc in #3976
• feat(utils): add max reduction type by @​imstevenpmwork in #4027
