Qwen2-7B-Instruct-GGUF

[!NOTE] This is a model that is assumed to perform well, but may require more testing and user feedback. Be aware, only models featured within the GUI of GPT4All, are curated and officially supported by Nomic. Use at your own risk.

About

• Static quants of https://huggingface.co/Qwen/Qwen2-7B-Instruct at commit 41c66b0
• Quantized by ThiloteE with llama.cpp commit 84eb2f4

These quants were created with a customized configuration that have been proven to be compatible with GPT4All and that fixes issues with bos and eos after feedback by Qwen developers.

Prompt Template (for GPT4All)

Example System Prompt:

<|im_start|>system
You are a helpful assistant.<|im_end|>

Chat Template:

<|im_start|>User
%1<|im_end|>
<|im_start|>assistant
%2<|im_end|>

Context Length

32768

Use a lower value during inference, if you do not have enough RAM or VRAM.

Qwen2-7B-Instruct

Introduction

Qwen2 is the new series of Qwen large language models. For Qwen2, we release a number of base language models and instruction-tuned language models ranging from 0.5 to 72 billion parameters, including a Mixture-of-Experts model. This repo contains the instruction-tuned 7B Qwen2 model.

Compared with the state-of-the-art opensource language models, including the previous released Qwen1.5, Qwen2 has generally surpassed most opensource models and demonstrated competitiveness against proprietary models across a series of benchmarks targeting for language understanding, language generation, multilingual capability, coding, mathematics, reasoning, etc.

Qwen2-7B-Instruct supports a context length of up to 131,072 tokens, enabling the processing of extensive inputs. Please refer to this section for detailed instructions on how to deploy Qwen2 for handling long texts.

For more details, please refer to our blog, GitHub, and Documentation. <br>

Model Details

Qwen2 is a language model series including decoder language models of different model sizes. For each size, we release the base language model and the aligned chat model. It is based on the Transformer architecture with SwiGLU activation, attention QKV bias, group query attention, etc. Additionally, we have an improved tokenizer adaptive to multiple natural languages and codes.

Training details

We pretrained the models with a large amount of data, and we post-trained the models with both supervised finetuning and direct preference optimization.

Requirements

The code of Qwen2 has been in the latest Hugging face transformers and we advise you to install transformers>=4.37.0, or you might encounter the following error:

KeyError: 'qwen2'

Quickstart

Here provides a code snippet with apply_chat_template to show you how to load the tokenizer and model and how to generate contents.

from transformers import AutoModelForCausalLM, AutoTokenizer
device = "cuda" # the device to load the model onto

model = AutoModelForCausalLM.from_pretrained(
	"Qwen/Qwen2-7B-Instruct",
	torch_dtype="auto",
	device_map="auto"
)
tokenizer = AutoTokenizer.from_pretrained("Qwen/Qwen2-7B-Instruct")

prompt = "Give me a short introduction to large language model."
messages = [
	{"role": "system", "content": "You are a helpful assistant."},
	{"role": "user", "content": prompt}
]
text = tokenizer.apply_chat_template(
	messages,
	tokenize=False,
	add_generation_prompt=True
)
model_inputs = tokenizer([text], return_tensors="pt").to(device)

generated_ids = model.generate(
	model_inputs.input_ids,
	max_new_tokens=512
)
generated_ids = [
	output_ids[len(input_ids):] for input_ids, output_ids in zip(model_inputs.input_ids, generated_ids)
]

response = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0]

Processing Long Texts

To handle extensive inputs exceeding 32,768 tokens, we utilize YARN, a technique for enhancing model length extrapolation, ensuring optimal performance on lengthy texts.

For deployment, we recommend using vLLM. You can enable the long-context capabilities by following these steps:

1. Install vLLM: You can install vLLM by running the following command.

pip install "vllm>=0.4.3"

Or you can install vLLM from source.

1. Configure Model Settings: After downloading the model weights, modify the config.json file by including the below snippet:

	{
		"architectures": [
			"Qwen2ForCausalLM"
		],
		// ...
		"vocab_size": 152064,

		// adding the following snippets
		"rope_scaling": {
			"factor": 4.0,
			"original_max_position_embeddings": 32768,
			"type": "yarn"
		}
	}

This snippet enable YARN to support longer contexts.

1. Model Deployment: Utilize vLLM to deploy your model. For instance, you can set up an openAI-like server using the command:

python -m vllm.entrypoints.openai.api_server --served-model-name Qwen2-7B-Instruct --model path/to/weights

Then you can access the Chat API by:

curl http://localhost:8000/v1/chat/completions \
	-H "Content-Type: application/json" \
	-d '{
	"model": "Qwen2-7B-Instruct",
	"messages": [
		{"role": "system", "content": "You are a helpful assistant."},
		{"role": "user", "content": "Your Long Input Here."}
	]
	}'

For further usage instructions of vLLM, please refer to our Github.

Note: Presently, vLLM only supports static YARN, which means the scaling factor remains constant regardless of input length, potentially impacting performance on shorter texts. We advise adding the rope_scaling configuration only when processing long contexts is required.
