## Highlights
|
49 |
+
1. In LongLoRA approach, The proposed shifted short attention is easy to implement, compatible with Flash-Attention, and is not required during inference.
|
50 |
+
2. We released all our models, including models from 7B to 70B, context length from 8k to 100k, including [LLaMA2-LongLoRA-7B-100k](https://huggingface.co/Yukang/Llama-2-7b-longlora-100k-ft), [LLaMA2-LongLoRA-13B-64k](https://huggingface.co/Yukang/Llama-2-13b-longlora-64k), and [LLaMA2-LongLoRA-70B-32k](https://huggingface.co/Yukang/Llama-2-70b-longlora-32k).
|
51 |
+
3. We built up a long-context instruction-following dataset, [LongAlpaca-12k](#longalpaca-data). We released the corresponding [LongAlpaca-7B](https://huggingface.co/Yukang/LongAlpaca-7B), [LongAlpaca-13B](https://huggingface.co/Yukang/LongAlpaca-13B) and [LongAlpaca-70B](https://huggingface.co/Yukang/LongAlpaca-70B) models. To our best knowledge, this is the first open-sourced long-context 70B model.

## LongAlpaca Data
|
82 |
+
|
83 |
+
LongAlpaca-12k contains 9k long QA data that we collected and 3k short QA sampled from the original [Alpaca data](https://github.com/tatsu-lab/stanford_alpaca/blob/main/alpaca_data.json). This is to avoid the case that the model might degrade at short instruction following. The data we collect contains various types and amounts as the following figure.
|
84 |
+
|
85 |
+
| Data | Short QA | Long QA | Total | Download |
|
86 |
+
|:---------------|----------|----------|----------|----------|
|
87 |
+
| LongAlpaca-12k | 3k | 9k | 12k | [Link](https://drive.google.com/file/d/1JVC1p_Ht-1h61tKitOCW0blnCHf-552U/view?usp=share_link) |
|
88 |
+
|
89 |
+
Following the original Alpaca format, our Long QA data uses the following prompts for fine-tuning:
|
90 |
+
- `instruction`: `str`, describes the task the model should perform. For example, to answer a question after reading a book section or paper. We vary the contents and questions to make instructions diverse.
|
91 |
+
- `output`: `str`, the answer to the instruction.
|
92 |
+
|
93 |
+
We did not use the `input` format in the Alpaca format for simplicity.
|
94 |
+

- Please remember to change `path_to/Llama-2-7b-hf`, `path_to_saving_checkpoints`, `path_to_cache` to your own directory.
|
170 |
+
- Note that you can change `model_max_length` to other values.
|
171 |
+
- You could change `ds_configs/stage2.json` to `ds_configs/stage3.json` if you want.
|
172 |
+
- Please set `use_flash_attn` as `False` if you use V100 machines or do not install flash attention.
|
173 |
+
- You can set `low_rank_training` as `False` if you want to use fully fine-tuning. It will cost more GPU memory and slower, but the performance will be a bit better.
|
174 |
+
- When training is finished, to get the full model weight:
|
175 |
+
```
|
176 |
+
cd path_to_saving_checkpoints && python zero_to_fp32.py . pytorch_model.bin
|
177 |
+
```
|
178 |

|
205 |

- We typically make supervised fine-tuning upon the fine-tuned context extended models, `path_to_finetuned_models`, like `Llama-2-13b-longlora-32k` or `Llama-2-13b-longlora-32k-ft`.
|
206 |
+
- During our dataset collection, it is hard for us to collect many high-quality QA that are larger than 32768. Thus, if you use our `LongQA.json`, please also set `model_max_length` as 32768.
|
207 |
+
|
208 |
+
|
209 |
+
### Get trainable weights in low-rank training
|
210 |
+
In low-rank training, we set embedding and normalization layers as trainable. Please use the following line to extract the trainable weights `trainable_params.bin` from `pytorch_model.bin`
|
211 |
+
```
|
212 |
+
python3 get_trainable_weights.py --checkpoint_path path_to_saving_checkpoints --trainable_params "embed,norm"
|
213 |
+
```
|
214 |
+
|
215 |
+
### Merge LoRA Weight
|
216 |
+
Merge the LoRA weights of `pytorch_model.bin` and trainable parameters `trainable_params.bin`, save the resulting model into your desired path in the Hugging Face format:
|
217 |
+
```
|
218 |
+
python3 merge_lora_weights_and_save_hf_model.py \
|
219 |
+
--base_model path_to/Llama-2-7b-hf \
|
220 |
+
--peft_model path_to_saving_checkpoints \
|
221 |
+
--context_size 8192 \
|
222 |
+
--save_path path_to_saving_merged_model
|
223 |
+
```
|
224 |
+
For example,
|
225 |
+
```
|
226 |
+
python3 merge_lora_weights_and_save_hf_model.py \
|
227 |
+
--base_model /dataset/pretrained-models/Llama-2-7b-hf \
|
228 |
+
--peft_model /dataset/yukangchen/hf_models/lora-models/Llama-2-7b-longlora-8k \
|
229 |
+
--context_size 8192 \
|
230 |
+
--save_path /dataset/yukangchen/models/Llama-2-7b-longlora-8k-merged
|
231 |
+
```
|
232 |
+
|
233 |
+
|
234 |
+
## Evaluation
|
235 |
+
### Perplexity Validation
|
236 |
+
To evaluate a model that is trained in the low-rank setting, please set both `base_model` and `peft_model`. `base_model` is the pre-trained weight. `peft_model` is the path to the saved checkpoint, which should contain `trainable_params.bin`, `adapter_model.bin` and `adapter_config.json`. For example,
|
237 |
+
```
|
238 |
+
python3 eval.py --seq_len 8192 --context_size 8192 --batch_size 1 --base_model path_to/Llama-2-7b-hf --peft_model path_to_saving_checkpoints --data_path pg19/test.bin
|
239 |
+
```
|
240 |
+
|
241 |
+
To evaluate a model that is fully fine-tuned, you only need to set `base_model` as the path to the saved checkpoint, which should contain `pytorch_model.bin` and `config.json`. `peft_model` should be ignored.
|
242 |
+
```
|
243 |
+
python3 eval.py --seq_len 8192 --context_size 8192 --batch_size 1 --base_model path_to_saving_checkpoints --data_path pg19/test.bin
|
244 |
+
```
|
245 |
+
|
246 |
+
- Note that `--seq_len` is to set the sequence length for evaluation. `--context_size` is to set the context length of the model during fine-tuning. `--seq_len` should not be larger than `--context_size`.
|
247 |
+
|
248 |
+
- We have already tokenized the validation and test splits of PG19 and proof-pile dataset into `pg19/validation.bin`, `pg19/test.bin`, and `proof-pile/test_sampled_data.bin`, with the tokenizer of LLaMA. `proof-pile/test_sampled_data.bin` contains 128 documents that are randomly sampled from the total proof-pile test split. For each document, it has at least 32768 tokens. We also release the sampled ids in [proof-pile/test_sampled_ids.bin](https://drive.google.com/file/d/1cnzWODLRQYAd7HeugzLCIhaqzaLZv7J5/view?usp=share_link). You can download them from the links below.

### Passkey Retrieval
|
258 |
+
We provide a manner to test the passkey retrieval accuracy. For example,
|
259 |
+
```
|
260 |
+
python3 passkey_retrivial.py \
|
261 |
+
--context_size 32768 \
|
262 |
+
--base_model path_to/Llama-2-7b-longlora-32k \
|
263 |
+
--max_tokens 32768 \
|
264 |
+
--interval 1000
|
265 |
+
```
|
266 |
+
- Note that the `context_size` is the context length during fine-tuning.
|
267 |
+
- `max_tokens` is maximum length for the document in passkey retrieval evaluation.
|
268 |
+
- `interval` is the interval during the document length increasing. It is a rough number because the document increases by sentences.
|

```
|
286 |
+
python3 inference.py \
|
287 |
+
--base_model /data/models/Llama-2-13b-chat-longlora-32k-sft \
|
288 |
+
--question "Why doesn't Professor Snape seem to like Harry?" \

+
Note that you can ignore `material_type` or `material_title`.
|
297 |
+
|
298 |
+
To ask a question related to a paper:
|
299 |
+
```
|
300 |
+
python3 inference.py \
|
301 |
+
--base_model /data/models/Llama-2-13b-chat-longlora-32k-sft \

### Online Demo
|
311 |
+
To deploy your own demo run
|
312 |
+
```
|
313 |
+
python3 demo.py \
|
314 |
+
--base_model path_to_model \
|
315 |
+
--context_size $context_size \
|
316 |
+
--max_gen_len $max_gen_len \
|
317 |
+
--flash_attn True
|
318 |
+
```
|
319 |
+
Example
|
320 |
+
```
|
321 |
+
python3 demo.py \
|
322 |
+
--base_model /data/models/Llama-2-13b-chat-longlora-32k-sft \
|
323 |
+
--context_size 32768 \
|
324 |
+
--max_gen_len 512 \
|
325 |
+
--flash_attn True
|
326 |
+
```
|
327 |
+
- Note that `flash_attn=True` will make the generation slow but save much GPU memory.
|
328 |
+
|
329 |
+
## Data Generation via Pdf2text
|
330 |
+
During our dataset collection, we convert paper and books from pdf to text. The conversion quality has a large influence on the final model quality. We think that this step is non-trivial. We release the tool for the pdf2txt conversion, in the folder `pdf2txt`. It is built upon `pdf2image`, `easyocr`, `ditod` and `detectron2`. Please refer to the [README.md](pdf2txt/README.md) in `pdf2txt` for more details.
