## Description
|
||||
|
||||
This repo contains AWQ model files for [SkunkworksAI's Mistralic 7B-1](https://huggingface.co/SkunkworksAI/Mistralic-7B-1).
|
||||
|
||||
|
||||
### 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/Mistralic-7B-1-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/Mistralic-7B-1-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}")
|
||||
```

||||

<!-- README_AWQ.md-use-from-tgi start -->
|
||||
## Serving this model from Text Generation Inference (TGI)
|
||||
|
||||
Use TGI version 1.1.0 or later. The official Docker container is: `ghcr.io/huggingface/text-generation-inference:1.1.0`
|
||||
|
||||
Example Docker parameters:
|
||||
|
||||
```shell
|
||||
--model-id TheBloke/Mistralic-7B-1-AWQ --port 3000 --quantize awq --max-input-length 3696 --max-total-tokens 4096 --max-batch-prefill-tokens 4096
|
||||
```
|
||||
|
||||
Example Python code for interfacing with TGI (requires huggingface-hub 0.17.0 or later):
|
||||
|
||||
```shell
|
||||
pip3 install huggingface-hub
|
||||
```
|
||||
|
||||
```python
|
||||
from huggingface_hub import InferenceClient
|
||||
|
||||
endpoint_url = "https://your-endpoint-url-here"
|
||||
|
||||
prompt = "Tell me about AI"
|
||||
prompt_template=f'''Below is an instruction that describes a task. Write a response that appropriately completes the request.
|
||||
|
||||

||||

|
||||

'''
|
||||
|
||||
client = InferenceClient(endpoint_url)
|
||||
response = client.text_generation(prompt,
|
||||

|
||||

|
||||

## 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/Mistralic-7B-1-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.
|
||||
|
||||
### System: {system_message}
|
||||
|
||||
### Instruction: {prompt}
|
||||
|
||||

|
||||
|
||||

|
||||
|
||||
tokens = tokenizer(
|
||||
prompt_template,
|
||||

|
||||
).input_ids.cuda()
|
||||
|
||||
# Generate output
|
||||

|
||||

|
||||
|
||||
"""
|
||||
# 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)

``model.load_state_dict(state_dict)`` will remove all the deepspeed magic from it.
