GLM

GLM is a General Language Model pretrained with an autoregressive blank-filling objective and can be finetuned on various natural language understanding and generation tasks.

Please refer to our paper for a detailed description of GLM:

All NLP Tasks Are Generation Tasks: A General Pretraining Framework

Zhengxiao Du*, Yujie Qian*, Xiao Liu, Ming Ding, Jiezhong Qiu, Zhilin Yang, Jie Tang (*: equal contribution)

Part of the code is based on Megatron-LM and PET.

Get Started

Docker Image

We prepare two docker images based on CUDA 10.2 and CUDA 11.2. You can pull the pre-built images from Docker Hub and run with docker v19.03+

docker run --gpus all --rm -it --ipc=host zxdu20/glm-cuda102

or replace glm-cuda102 with glm-cuda112.

You can also modify the image according to your requirements in docker/cuda102.dockerfile and build the image yourself

  docker build -f cuda102.dockerfile . -t glm-cuda102

Manual Installation

Please first install PyTorch (we use 1.7.0) and apex, and then install other dependencies by pip install -r requirements.txt

Clone this repo

git clone https://github.com/THUDM/GLM
cd GLM

Usage

We provide scripts for finetuning GLM on some downstream tasks.

SuperGLUE

Download the SuperGlue data and check the experiment setup in scripts/ds_finetune_superglue.sh. Note that DATA_ROOT, CHECKPOINT_PATH, SAVE_PATH need to be changed to your local path. You may also change the batch-size and nproc_per_node according to your available hardware.
Run the following script (use the COPA dataset as an example)

bash scripts/ds_finetune_superglue.sh \
     config_tasks/model_blocklm_10B.sh \
     config_tasks/task_copa.sh

We also implement P-Tuning in our code. Run the following script to integrate p-tuning:

bash scripts/ds_finetune_superglue_prompt.sh \
     config_tasks/model_blocklm_10B.sh \
     config_tasks/task_copa.sh

To apply GLM to a new NLU dataset with cloze-filling finetuning, implement a DataProcessor in tasks/superglue/dataset.py for data loading and add a PVP in tasks/superglue/pvp.py for the cloze question. More details can be found here.

Text Summarization

Download the Gigaword, CNN/Daily Mail or XSum dataset and check the experiment setup in scripts/ds_finetune_seq2seq.sh. Change DATA_ROOT, CHECKPOINT_PATH, SAVE_PATH to your local path.

Run the following script (use the CNN/Daily Mail dataset as an example)

bash scripts/ds_finetune_seq2seq.sh \ 
   config_tasks/model_blocklm_10B.sh \ 
   config_tasks/seq_cnndm_org.sh

The summaries are written into ./runs/experiment_name/test.jsonl.hyps. The references are written into test.jsonl.refs in the same directory. For calculating rouge, install file2rouge and download Stanford CoreNLP from here. Run the following script
```
bash scripts/evaluate_seq2seq.sh \
 ./runs/experiment_name/test.jsonl.hyps ./runs/experiment_name/test.jsonl.refs
```

Language Modeling

LAMBADA Cloze Accuracy

Download the LAMBADA data and change DATA_ROOT, CHECKPOINT_PATH in scripts/evaluate_lm.sh
Run the following script

bash scripts/evaluate_lm.sh \ 
     config_tasks/model_blocklm_large_generation.sh \
     config_tasks/zero_lambada.sh

LM Perplexity

Download our test set of wikibook or Wikitext103 dataset and change DATA_ROOT, CHECKPOINT_PATH in scripts/evaluate_lm.sh

Run the following script

bash scripts/evaluate_lm.sh \ 
   config_tasks/model_blocklm_large_generation.sh \
   config_tasks/zero_wikitext.sh

Blank Language Model

Download the Yahoo dataset and check the experiment setup in scripts/finetune_blank.sh. Change DATA_ROOT, CHECKPOINT_PATH, SAVE_PATH to your local path.
Run the following script

bash scripts/finetune_blank.sh \ 
     config_tasks/model_blocklm_large.sh \ 
     config_tasks/seq_blank.sh

Blank Filling (Interactive)

Change CHECKPOINT_PATH to your local path. Run the following script

bash scripts/generate_block.sh \
     config_tasks/model_blocklm_large.sh

Example:

Context: Ng is an adjunct professor at [MASK] (formerly associate professor and Director of its Stanford AI Lab or SAIL ). Also a pioneer in online education, Ng co-founded Coursera and deeplearning.ai.

GLM: [CLS] ng is an adjunct professor at [MASK] ( formerly associate professor and director of its stanford ai lab or sail ) . also a pioneer in online education , ng co - founded coursera and deeplearning . ai . [PAD] <|startofpiece|> the stanford university

Pretrain

Run the following script to pre-train the GLM-Large model

bash scripts/ds_pretrain_nvidia.sh config/ds_block_large.sh

The script scripts/ds_pretrain_nvidia.sh launches the training program with DeepSpeed. You should change NUM_WORKERS and NUM_GPUS_PER_WORKER to the number of workers and the number of gpus per worker. Also change HOST_FILE_PATH to the path to an OpenMPI-style hostfile. More details about DeepSpeed launcher can be found here.

The file config/ds_block_large.sh defines the hyperparameters for pretraining. Most of the arguments are fairly self-explanatory. Specifically, --train-data can be multiple keywords defined in NAMED_CORPORA in data_utils/corpora.py. The hyperparameters of the optimizer are defined in the corresponding json file under config. The semantics of the json file can be found here.
