# Qwen2-1.5B-Instruct-quantized.w8a8
|
||||
|
||||
## Model Overview
|
||||
- **Model Architecture:** Qwen2
|
||||
- **Input:** Text
|
||||
- **Output:** Text
|
||||
- **Model Optimizations:**
|
||||
- **Activation quantization:** INT8
|
||||
- **Weight quantization:** INT8
|
||||
- **Intended Use Cases:** Intended for commercial and research use in English. Similarly to [Qwen2-1.5B-Instruct](https://huggingface.co/Qwen/Qwen2-1.5B-Instruct), this models is intended for assistant-like chat.
|
||||
- **Out-of-scope:** Use in any manner that violates applicable laws or regulations (including trade compliance laws). Use in languages other than English.
|
||||
- **Release Date:** 7/11/2024
|
||||
- **Version:** 1.0
|
||||
- **License(s):** [Apache-2.0](https://www.apache.org/licenses/LICENSE-2.0)
|
||||
- **Model Developers:** Neural Magic
|
||||
|
||||
Quantized version of [Qwen2-1.5B-Instruct](https://huggingface.co/Qwen/Qwen2-1.5B-Instruct).
|
||||
It achieves an average score of 55.05 on the [OpenLLM](https://huggingface.co/spaces/open-llm-leaderboard/open_llm_leaderboard) benchmark (version 1), whereas the unquantized model achieves 55.17.
|
||||
|
||||
### Model Optimizations
|
||||
|
||||
This model was obtained by quantizing the weights of [Qwen2-1.5B-Instruct](https://huggingface.co/Qwen/Qwen2-1.5B-Instruct) to INT8 data type.
|
||||
This optimization reduces the number of bits used to represent weights and activations from 16 to 8, reducing GPU memory requirements (by approximately 50%) and increasing matrix-multiply compute throughput (by approximately 2x).
|
||||
Weight quantization also reduces disk size requirements by approximately 50%.
|
||||
|
||||
Only weights and activations of the linear operators within transformers blocks are quantized.
|
||||
Weights are quantized with a symmetric static per-channel scheme, where a fixed linear scaling factor is applied between INT8 and floating point representations for each output channel dimension.
|
||||
Activations are quantized with a symmetric dynamic per-token scheme, computing a linear scaling factor at runtime for each token between INT8 and floating point representations.
|
||||
The [GPTQ](https://arxiv.org/abs/2210.17323) algorithm is applied for quantization, as implemented in the [llm-compressor](https://github.com/vllm-project/llm-compressor) library.
|
||||
GPTQ used a 1% damping factor and 256 sequences of 8,192 random tokens.
|
||||
|
||||
|
||||
## Deployment
|
||||
|
||||
### Use with vLLM
|
||||
|
||||
This model can be deployed efficiently using the [vLLM](https://docs.vllm.ai/en/latest/) backend, as shown in the example below.
|
||||
|
||||
```python
|
||||
from vllm import LLM, SamplingParams
|
||||
from transformers import AutoTokenizer
|
||||
|
||||
model_id = "neuralmagic/Qwen2-1.5B-Instruct-quantized.w8a8"
|
||||
number_gpus = 1
|
||||
|
||||
sampling_params = SamplingParams(temperature=0.7, top_p=0.8, max_tokens=256)
|
||||
|
||||
tokenizer = AutoTokenizer.from_pretrained(model_id)
|
||||
|
||||
messages = [
|
||||
{"role": "system", "content": "You are a pirate chatbot who always responds in pirate speak!"},
|
||||
{"role": "user", "content": "Who are you?"},
|
||||
]
|
||||
|
||||
prompts = tokenizer.apply_chat_template(messages, add_generation_prompt=True, tokenize=False)
|
||||
|
||||
llm = LLM(model=model_id, tensor_parallel_size=number_gpus)
|
||||
|
||||
outputs = llm.generate(prompts, sampling_params)
|
||||
|
||||
generated_text = outputs[0].outputs[0].text
|
||||
print(generated_text)
|
||||
```
|
||||
|
||||
vLLM aslo supports OpenAI-compatible serving. See the [documentation](https://docs.vllm.ai/en/latest/) for more details.
|
||||
|
||||
### Use with transformers
|
||||
|
||||
The following example contemplates how the model can be deployed in Transformers using the `generate()` function.
|
||||
|
||||
```python
|
||||
from transformers import AutoTokenizer, AutoModelForCausalLM
|
||||
|
||||
model_id = "neuralmagic/Qwen2-1.5B-Instruct-quantized.w8a8"
|
||||
|
||||
tokenizer = AutoTokenizer.from_pretrained(model_id)
|
||||
model = AutoModelForCausalLM.from_pretrained(
|
||||
model_id,
|
||||
torch_dtype="auto",
|
||||
device_map="auto",
|
||||
)
|
||||
|
||||
messages = [
|
||||
{"role": "system", "content": "You are a pirate chatbot who always responds in pirate speak!"},
|
||||
{"role": "user", "content": "Who are you?"},
|
||||
]
|
||||
|
||||
input_ids = tokenizer.apply_chat_template(
|
||||
messages,
|
||||
add_generation_prompt=True,
|
||||
return_tensors="pt"
|
||||
).to(model.device)
|
||||
|
||||
terminators = [
|
||||
tokenizer.eos_token_id,
|
||||
tokenizer.convert_tokens_to_ids("<|eot_id|>")
|
||||
]
|
||||
|
||||
outputs = model.generate(
|
||||
input_ids,
|
||||
max_new_tokens=256,
|
||||
eos_token_id=terminators,
|
||||
do_sample=True,
|
||||
temperature=0.7,
|
||||
top_p=0.8,
|
||||
)
|
||||
response = outputs[0][input_ids.shape[-1]:]
|
||||
print(tokenizer.decode(response, skip_special_tokens=True))
|
||||
```
|
||||
|
||||
## Creation
|
||||
|
||||
This model was created by using the [llm-compressor](https://github.com/vllm-project/llm-compressor) library as presented in the code snipet below.
|
||||
|
||||
```python
|
||||
from transformers import AutoTokenizer
|
||||
from datasets import Dataset
|
||||
from llmcompressor.transformers import SparseAutoModelForCausalLM, oneshot
|
||||
from llmcompressor.modifiers.quantization import GPTQModifier
|
||||
import random
|
||||
|
||||
model_id = "Qwen/Qwen2-1.5B-Instruct"
|
||||
|
||||
num_samples = 256
|
||||
max_seq_len = 8192
|
||||
|
||||
tokenizer = AutoTokenizer.from_pretrained(model_id)
|
||||
|
||||
max_token_id = len(tokenizer.get_vocab()) - 1
|
||||
input_ids = [[random.randint(0, max_token_id) for _ in range(max_seq_len)] for _ in range(num_samples)]
|
||||
attention_mask = num_samples * [max_seq_len * [1]]
|
||||
ds = Dataset.from_dict({"input_ids": input_ids, "attention_mask": attention_mask})
|
||||
|
||||
recipe = GPTQModifier(
|
||||
targets="Linear",
|
||||
scheme="W8A8",
|
||||
ignore=["lm_head"],
|
||||
dampening_frac=0.01,
|
||||
)
|
||||
|
||||
model = SparseAutoModelForCausalLM.from_pretrained(
|
||||
model_id,
|
||||
device_map="auto",
|
||||
trust_remote_code=True,
|
||||
)
|
||||
|
||||
oneshot(
|
||||
model=model,
|
||||
dataset=ds,
|
||||
recipe=recipe,
|
||||
max_seq_length=max_seq_len,
|
||||
num_calibration_samples=num_samples,
|
||||
)
|
||||
|
||||
model.save_pretrained("Qwen2-1.5B-Instruct-quantized.w8a18)
|
||||
```
|
||||
|
||||
|
||||
## Evaluation
|
||||
|
||||
The model was evaluated on the [OpenLLM](https://huggingface.co/spaces/open-llm-leaderboard/open_llm_leaderboard) leaderboard tasks (version 1) with the [lm-evaluation-harness](https://github.com/EleutherAI/lm-evaluation-harness/tree/383bbd54bc621086e05aa1b030d8d4d5635b25e6) (commit 383bbd54bc621086e05aa1b030d8d4d5635b25e6) and the [vLLM](https://docs.vllm.ai/en/stable/) engine, using the following command:
|
||||
```
|
||||
lm_eval \
|
||||
--model vllm \
|
||||
--model_args pretrained="neuralmagic/Qwen2-1.5B-Instruct-quantized.w8a8",dtype=auto,gpu_memory_utilization=0.4,add_bos_token=True,max_model_len=4096,tensor_parallel_size=1 \
