Datasets

Our script now supports the following datasets:

Please refer to data/README.md for details.

Some dataset requires confirmation before using it, so we recommend logging in with your HuggingFace account using these command.

pip install --upgrade huggingface_hub

Getting Started

Data Preparation (optional)

Please refer to data/example_dataset for checking the details about the format of dataset files. You can either use a single .json file or a dataset loading script with multiple files to create a custom dataset.

Note: please update data/dataset_info.json to use your custom dataset. About the format of this file, please refer to data/README.md.

Dependence Installation (optional)

git clone https://github.com/hiyouga/ChatGLM-Efficient-Tuning.git
conda create -n chatglm_etuning python=3.10
conda activate chatglm_etuning
cd ChatGLM-Efficient-Tuning
pip install -r requirements.txt

Note: r is the lora rank, p is the number of prefix tokens, l is the number of trainable layers, ex/s is the examples per second in training. The gradient_accumulation_steps is set to 1. All are evaluated on a single Tesla V100 (32G) GPU, they are approximated values and may vary in different GPUs.

Fine-tuning ChatGLM: A Case

Training Results

We use the whole alpaca_gpt4_zh dataset to fine-tune the ChatGLM model with LoRA (r=8) for one epoch, using the default hyper-parameters. The loss curve during training is presented below.

Evaluation Results

We select 100 instances in the alpaca_gpt4_zh dataset to evaluate the fine-tuned ChatGLM model and compute the BLEU and ROUGE scores. The results are presented below.

Score Original FZ (l=2) PT (p=16) LoRA (r=8)
BLEU-4 15.75 16.85 16.06 17.01 (+1.26)
Rouge-1 34.51 36.62 34.80 36.77 (+2.26)
Rouge-2 15.11 17.04 15.32 16.83 (+1.72)
Rouge-l 26.18 28.17 26.35 28.86 (+2.68)
Params (%) / 4.35% 0.06% 0.06%

FZ: freeze tuning, PT: P-Tuning V2 (we use pre_seq_len=16 for fair comparison with LoRA), Params: the percentange of trainable parameters.

Compared with Existing Implementations

  • THUDM/ChatGLM-6B
    • Official implementation of fine-tuning ChatGLM with P-Tuning v2 on the ADGEN dataset.
    • Our fine-tuning script is largely depend on it. We further implement the LoRA tuning method. Additionally, we dynamically pad the inputs to the longest sequence in the batch instead of the maximum length, to accelerate the fine-tuning.
  • mymusise/ChatGLM-Tuning
    • An unoffical implementation of fine-tuning ChatGLM with LoRA on the Stanford Alpaca dataset.
    • We borrowed some ideas from it. Our fine-tuning script integrates the data pre-processing part into the training procedure, so we need not generate a pre-processed dataset before training.
  • ssbuild/chatglm_finetuning
  • lich99/ChatGLM-finetune-LoRA
  • liucongg/ChatGLM-Finetuning
    • An unofficial implementation of fine-tuning ChatGLM with several methods including Freeze, LoRA and P-Tuning on the industrial dataset.
    • We are aim to incorporate more instruction-following datasets for fine-tuning the ChatGLM model.
  • yanqiangmiffy/InstructGLM
    • An unofficial implementation of fine-tuning ChatGLM that explores the ChatGLM's ability on the instruction-following datasets.
    • Our fine-tuning script integrates the data pre-processing part in to the training procedure.

TODO

  • Employing LangChain to easily build applications that are capable of leveraging external knowledge upon fine-tuned ChatGLM models.
  • Implementing the alignment algorithms to align human preferrences.
  • Incorporating Chinese datasets into the training sets.
  • Incorporating ChatGPT & GPT-4 self-chat data into the training sets.
  • Implementing the Freeze-Tuning and P-Tuning method.
  • Supporting Multi-GPUs fine-tuning.
  • Adding script for evaluation. (but it appears very slow, increasing batch size may help)
  • Loading from checkpoint.
  • Fine-tuning the quantized model.
  • Writing a guidebook about how to fine-tune ChatGLM with this framework.
  • Combining with state-of-the-art model editing algorithms. (e.g. MEND)
  • Incorporating the OpenAssistant Conversations Dataset for SFT and alignment.
