This is a Jax-based repo for LLM Prunning, It contains:
- the implementations of various LLM pruning methods of different granularity.
- pretraining and fine-tuning code for both GPU and TPU platforms.
- evaluation scripts for assessing model performance.


**We gratefully acknowledge the generous support of the Google TPU Research Cloud (TRC), which provided the computational resources used to build this repository.**

The repo is organized as follows:

```bash
├── pruning
│   ├── FLAP # including Wanda-sp and FLAP
│   ├── LLM-Pruner
│   ├── llmshearing # sheared llama
│   ├── minitron # including shortgpt
│   ├── SLEB # including sleb
│   ├── SliceGPT # including slicegpt
│   └── wanda # including sparsegpt and magnitude pruning
├── training
│   ├── fms_fsdp
│   └── maxtext
└── eval
```
where `pruning` is the collection of the pruning methods we experimented; `training` contains the LLM training frameworks we used, and we provided options for both TPU and GPU; `eval` contains JAX-compatible eval scripts we used to evaluate the pruned models.

## Get Started
### Pruning
In order to reproduce the results of the different pruning methods, we need to set up separate environments for different methods. The installation and command guide can be found at `pruning/<method>/README.md`. Below is an overview:

**Minitron**
```bash
cd pruning/minitron
bash scripts/install.sh
bash scripts/prune_llama3.1-8b.sh # contains minitron depth and width for llama3.1-8b
```

**ShortGPT**
```bash
cd pruning/minitron
bash scripts/install.sh
bash scripts/prune_llama2-7b.sh 
```

**Wanda, SparseGPT, Magnitude**
```bash
cd pruning/wanda
bash scripts/install.sh
bash scripts/prune_llama3.1-8b.sh # contains wanda, sparsegpt, and magnitude for llama3.1-8b
bash scripts/prune_llama2-7b.sh
bash scripts/prune_llama-7b.sh
```

**LLM-Pruner**
```bash
cd pruning/LLM-Pruner
bash scripts/install.sh
bash scripts/prune_llama-7b.sh
bash scripts/prune_llama2-7b.sh
bash scripts/prune_llama3.1-8b.sh
```

**Sheared Llama**
```bash
cd pruning/llmshearing
bash scripts/install.sh

mkdir -p llmshearing/data/red_pajama && cd llmshearing/data/red_pajama
huggingface-cli download Zephyr271828/redpajama-for-prune --repo-type dataset --local-dir for_prune
cd -

bash scripts/hf2composer.sh
bash scripts/prune_llama2-2.7b.sh
bash scripts/prune_llama2-1.3b.sh
bash scripts/prune_llama2-370m.sh
bash scripts/composer2hf.sh
```

### Training
**GPU**
To train on GPUs, please refer to the guide of [fms-fsdp](training/fms_fsdp/README.md) for details.

**TPU**
To train on TPUs, please refer to guide of [MaxText](training/maxtext/README.md) for details.

### Evaluation
**GPU**  
For evaluation on GPUS, you may run the following evaluation script on your HF checkpoint:
```bash
cd training/fms_fsdp
bash scripts/install.sh

cd ../../eval
bash scripts/eva
````
