Training of Hugging Face Models

We provide multiple examples of using LightSeq to accelerate Hugging Face model training.

BERT

Before doing next training, you need to switch to the BERT directory:

cd examples/training/huggingface/bert

First you should install these requirements:

pip install torch ninja transformers seqeval datasets

Then you can easily fine-tunes BERT on different tasks by running the bash scripts task_ner/run_ner.sh , task_glue/run_glue.sh, task_qa/run_qa.sh, etc.

You can also fine-tune the models using int8 mixed-precision by running task_ner/run_quant_ner.sh.

GPT2

Before doing next training, you need to switch to the GPT2 directory:

cd examples/training/huggingface/gpt

First you should install these requirements:

pip install -r requirements.txt

Then you can easily fine-tunes GPT2 by running the bash scripts run_clm.sh.

You can also fine-tune the models using int8 mixed-precision by running run_quant_clm.sh.

BART

Before doing next training, you need to switch to the GPT2 directory:

cd examples/training/huggingface/bart/summarization

First you should install these requirements:

pip install -r requirements.txt

Then you can easily fine-tunes BART by running the bash scripts run_summarization.sh.

ViT

Before doing next training, you need to switch to the ViT directory:

cd examples/training/huggingface/vit

First you should install these requirements:

pip install torch ninja transformers seqeval datasets

Then you can easily fine-tunes ViT by running the bash scripts run_vit.sh.

You can also fine-tune the models using int8 mixed-precision by running run_quant_vit.sh.

Gradient Communication Quantization

LightSeq support Hugging Face training using GCQ. Taking BERT as an example, first you need to switch to BERT directory you can easily fine-tunes BERT with GCQ on different tasks by running the bash scripts task_ner/run_gcq_ner.sh , task_glue/run_gcq_glue.sh, task_qa/run_gcq_qa.sh, etc.

You can use --enable_GCQ to enable GCQ in your multi-machine distributed training. You can set --GCQ_quantile to a float value between 0.0 and 1.0, which will use the quantile of gradient bucket as clip-max value when quantizing gradients. E.g., when setting --GCQ_quantile 0.99, the clip-max value is equal to the 0.99-th quantile of gradient bucket.

You can use multiple NICs in NCCL communication. E.g., if every machine has 4 NICs: eth0, eth1, eth2, eth3, you can use the following command.

export NCCL_SOCKET_IFNAME=eth0,eth1,eth2,eth3
