+## Description
+
+This repo contains AWQ model files for [YukangChen's LongAlpaca 70B](https://huggingface.co/Yukang/LongAlpaca-70B).
+
+
+### About AWQ
+
+AWQ is an efficient, accurate and blazing-fast low-bit weight quantization method, currently supporting 4-bit quantization. Compared to GPTQ, it offers faster Transformers-based inference.
+
+It is also now supported by continuous batching server [vLLM](https://github.com/vllm-project/vllm), allowing use of Llama AWQ models for high-throughput concurrent inference in multi-user server scenarios.
+
+As of September 25th 2023, preliminary Llama-only AWQ support has also been added to [Huggingface Text Generation Inference (TGI)](https://github.com/huggingface/text-generation-inference).
+
+Note that, at the time of writing, overall throughput is still lower than running vLLM or TGI with unquantised models, however using AWQ enables using much smaller GPUs which can lead to easier deployment and overall cost savings. For example, a 70B model can be run on 1 x 48GB GPU instead of 2 x 80GB.

+## Provided files, and AWQ parameters
+
+For my first release of AWQ models, I am releasing 128g models only. I will consider adding 32g as well if there is interest, and once I have done perplexity and evaluation comparisons, but at this time 32g models are still not fully tested with AutoAWQ and vLLM.
+
+Models are released as sharded safetensors files.

+## Serving this model from vLLM
+
+Documentation on installing and using vLLM [can be found here](https://vllm.readthedocs.io/en/latest/).
+
+Note: at the time of writing, vLLM has not yet done a new release with AWQ support.
+
+If you try the vLLM examples below and get an error about `quantization` being unrecognised, or other AWQ-related issues, please install vLLM from Github source.
+
+- When using vLLM as a server, pass the `--quantization awq` parameter, for example:
+
+```shell
+python3 python -m vllm.entrypoints.api_server --model TheBloke/LongAlpaca-70B-AWQ --quantization awq --dtype half
+```
+
+When using vLLM from Python code, pass the `quantization=awq` parameter, for example:
+
+```python
+from vllm import LLM, SamplingParams
+
+prompts = [
+    "Hello, my name is",
+    "The president of the United States is",
+    "The capital of France is",
+    "The future of AI is",
+]
+sampling_params = SamplingParams(temperature=0.8, top_p=0.95)
+
+llm = LLM(model="TheBloke/LongAlpaca-70B-AWQ", quantization="awq", dtype="half")
+
+outputs = llm.generate(prompts, sampling_params)
+
+# Print the outputs.
+for output in outputs:
+    prompt = output.prompt
+    generated_text = output.outputs[0].text
+    print(f"Prompt: {prompt!r}, Generated text: {generated_text!r}")
+```

+## How to use this AWQ model from Python code
+
+### Install the necessary packages
+
+Requires: [AutoAWQ](https://github.com/casper-hansen/AutoAWQ) 0.1.1 or later
+
+```shell
+pip3 install autoawq
+```
+
+If you have problems installing [AutoAWQ](https://github.com/casper-hansen/AutoAWQ) using the pre-built wheels, install it from source instead:
+
+```shell
+pip3 uninstall -y autoawq
+git clone https://github.com/casper-hansen/AutoAWQ
+cd AutoAWQ
+pip3 install .
+```
+
+### You can then try the following example code
+
+```python
+from awq import AutoAWQForCausalLM
+from transformers import AutoTokenizer
+
+model_name_or_path = "TheBloke/LongAlpaca-70B-AWQ"
+
+# Load model
+model = AutoAWQForCausalLM.from_quantized(model_name_or_path, fuse_layers=True,
+                                          trust_remote_code=False, safetensors=True)
+tokenizer = AutoTokenizer.from_pretrained(model_name_or_path, trust_remote_code=False)
+
+prompt = "Tell me about AI"
+prompt_template=f'''Below is an instruction that describes a task. Write a response that appropriately completes the request.
+
+### Instruction:
+{prompt}
+
+### Response:
+
+'''
+
+print("\n\n*** Generate:")
+
+tokens = tokenizer(
+    prompt_template,
+    return_tensors='pt'
+).input_ids.cuda()
+
+# Generate output
+generation_output = model.generate(
+    tokens,
+    do_sample=True,
+    temperature=0.7,
+    top_p=0.95,
+    top_k=40,
+    max_new_tokens=512
+)
+
+print("Output: ", tokenizer.decode(generation_output[0]))
+
+"""
+# Inference should be possible with transformers pipeline as well in future
+# But currently this is not yet supported by AutoAWQ (correct as of September 25th 2023)
+from transformers import pipeline
+
+print("*** Pipeline:")
+pipe = pipeline(
+    "text-generation",

+
+## Highlights
+1. In LongLoRA approach, The proposed shifted short attention is easy to implement, compatible with Flash-Attention, and is not required during inference.
+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).
+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
+
+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.
+
+| Data           | Short QA | Long QA  | Total    | Download |
+|:---------------|----------|----------|----------|----------|
+| LongAlpaca-12k | 3k       | 9k       | 12k      | [Link](https://huggingface.co/datasets/Yukang/LongAlpaca-12k) |
+
+Following the original Alpaca format, our Long QA data uses the following prompts for fine-tuning:
+- `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.
+- `output`: `str`, the answer to the instruction.
+
+We did not use the `input` format in the Alpaca format for simplicity.

+
+- Please remember to change `path_to/Llama-2-7b-hf`, `path_to_saving_checkpoints`, `path_to_cache` to your own directory.
+- Note that you can change `model_max_length` to other values.
+- You could change `ds_configs/stage2.json` to `ds_configs/stage3.json` if you want.
+- Please set `use_flash_attn` as `False` if you use V100 machines or do not install flash attention.
+- 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.
+- When training is finished, to get the full model weight:
+```
+cd path_to_saving_checkpoints && python zero_to_fp32.py . pytorch_model.bin
+```
+
+### Supervised Fine-tuning
+```

+        --tf32 True
+```
+- There is no need to make supervised fine-tuning upon the fine-tuned context extended models. It is all right to directly use base model as Llama2-chat models, as the amount of long instruction following data is enough for SFT.
+- Our long instruction following data can be found in [LongAlpaca-12k.json](https://huggingface.co/datasets/Yukang/LongAlpaca-12k).
+
+
+### Get trainable weights in low-rank training
+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`
+```
+python3 get_trainable_weights.py --checkpoint_path path_to_saving_checkpoints --trainable_params "embed,norm"
+```
+
+### Merge LoRA Weight
+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:
+```
+python3 merge_lora_weights_and_save_hf_model.py \
+        --base_model path_to/Llama-2-7b-hf \
+        --peft_model path_to_saving_checkpoints \
+        --context_size 8192 \
+        --save_path path_to_saving_merged_model
+```
+For example,
+```
+python3 merge_lora_weights_and_save_hf_model.py \
+        --base_model /dataset/pretrained-models/Llama-2-7b-hf \
+        --peft_model /dataset/yukangchen/hf_models/lora-models/Llama-2-7b-longlora-8k \
+        --context_size 8192 \
+        --save_path /dataset/yukangchen/models/Llama-2-7b-longlora-8k-merged
+```
+
+
+## Evaluation
+### Perplexity Validation
+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,
+```
+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
+```
+
+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.
+```
+python3 eval.py --seq_len 8192 --context_size 8192 --batch_size 1 --base_model path_to_saving_checkpoints --data_path pg19/test.bin
+```
+
+- 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`.
+
+- 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
+We provide a manner to test the passkey retrieval accuracy. For example,
+```
+python3 passkey_retrivial.py \
+        --context_size 32768 \
+        --base_model path_to/Llama-2-7b-longlora-32k \
+        --max_tokens 32768 \
+        --interval 1000
+```
+- Note that the `context_size` is the context length during fine-tuning.
+- `max_tokens` is maximum length for the document in passkey retrieval evaluation.
+- `interval` is the interval during the document length increasing. It is a rough number because the document increases by sentences.
+
+## Demo
+### Local Inference
+To chat with [Llama-2-13b-chat-longlora-32k-sft](https://huggingface.co/Yukang/Llama-2-13b-chat-longlora-32k-sft) or [Llama-2-70b-chat-longlora-32k-sft](https://huggingface.co/Yukang/Llama-2-70b-chat-longlora-32k-sft), you need to run `merge_lora_weights_and_save_hf_model.py` first, and then:
+```
+python3 inference.py  \
+        --base_model path_to_model \
+        --question $question \
+        --context_size $context_length \
+        --max_gen_len $max_gen_len \
+        --flash_attn True \
+        --material $material_content \
+        --material_type $material_type \
+        --material_title $material_title
+```
+To ask a question related to a book:
+```
+python3 inference.py  \
+        --base_model /data/models/Llama-2-13b-chat-longlora-32k-sft \
+        --question "Why doesn't Professor Snape seem to like Harry?" \
+        --context_size 32768 \
+        --max_gen_len 512 \
+        --flash_attn True \
+        --material "materials/Harry Potter and the Philosophers Stone_section2.txt" \
+        --material_type "book" \
+        --material_title "Harry Potter and the Philosophers Stone"
+```
+Note that you can ignore `material_type` or `material_title`.
+
+To ask a question related to a paper:
+```
+python3 inference.py  \
+        --base_model /data/models/Llama-2-13b-chat-longlora-32k-sft \
+        --question "What are the main contributions and novelties of this work?" \
+        --context_size 32768 \
+        --max_gen_len 512 \
+        --flash_attn True \
+        --material "materials/paper1.txt" \
+        --material_type "paper"
+```
+
+### Online Demo
+To deploy your own demo run 
+```
+python3 demo.py  \
+	--base_model path_to_model \
+	--context_size $context_size \
+	--max_gen_len $max_gen_len \
+	--flash_attn True
+```
+Example 
+```
+python3 demo.py  \
+	--base_model /data/models/Llama-2-13b-chat-longlora-32k-sft \
+	--context_size 32768 \
+	--max_gen_len 512 \
+	--flash_attn True
+```
+- Note that `flash_attn=True` will make the generation slow but save much GPU memory.
+
+## Data Generation via Pdf2text
+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.
