# Qwen2.5-Coder-7B-Instruct-bnb-4bit |
|
|
|
## Introduction |
|
|
|
Qwen2.5-Coder is the latest series of Code-Specific Qwen large language models (formerly known as CodeQwen). For Qwen2.5-Coder, we release three base language models and instruction-tuned language models, 1.5, 7 and 32 (coming soon) billion parameters. Qwen2.5-Coder brings the following improvements upon CodeQwen1.5: |
|
|
|
- Significantly improvements in **code generation**, **code reasoning** and **code fixing**. Base on the strong Qwen2.5, we scale up the training tokens into 5.5 trillion including source code, text-code grounding, Synthetic data, etc. |
|
- A more comprehensive foundation for real-world applications such as **Code Agents**. Not only enhancing coding capabilities but also maintaining its strengths in mathematics and general competencies. |
|
- **Long-context Support** up to 128K tokens. |
|
|
|
**This repo contains the instruction-tuned 7B Qwen2.5-Coder model**, which has the following features: |
|
- Type: Causal Language Models |
|
- Training Stage: Pretraining & Post-training |
|
- Architecture: transformers with RoPE, SwiGLU, RMSNorm, and Attention QKV bias |
|
- Number of Parameters: 7.61B |
|
- Number of Paramaters (Non-Embedding): 6.53B |
|
- Number of Layers: 28 |
|
- Number of Attention Heads (GQA): 28 for Q and 4 for KV |
|
- Context Length: Full 131,072 tokens |
|
- Please refer to [this section](#processing-long-texts) for detailed instructions on how to deploy Qwen2.5 for handling long texts. |
|
|
|
For more details, please refer to our [blog](https://qwenlm.github.io/blog/qwen2.5-coder/), [GitHub](https://github.com/QwenLM/Qwen2.5-Coder), [Documentation](https://qwen.readthedocs.io/en/latest/), [Arxiv](https://arxiv.org/abs/2409.12186). |
|
|
|
## Requirements |
|
|
|
The code of Qwen2.5-Coder has been in the latest Hugging face `transformers` and we advise you to use the latest version of `transformers`. |
|
|
|
With `transformers<4.37.0`, you will 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. |
|
|
|
```python |
|
from transformers import AutoModelForCausalLM, AutoTokenizer |
|
|
|
model_name = "Qwen/Qwen2.5-Coder-7B-Instruct" |
|
|
|
model = AutoModelForCausalLM.from_pretrained( |
|
model_name, |
|
torch_dtype="auto", |
|
device_map="auto" |
|
) |
|
tokenizer = AutoTokenizer.from_pretrained(model_name) |
|
|
|
prompt = "write a quick sort algorithm." |
|
messages = [ |
|
{"role": "system", "content": "You are Qwen, created by Alibaba Cloud. 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(model.device) |
|
|
|
generated_ids = model.generate( |
|
**model_inputs, |
|
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 |
|
|
|
The current `config.json` is set for context length up to 32,768 tokens. |
|
To handle extensive inputs exceeding 32,768 tokens, we utilize [YaRN](https://arxiv.org/abs/2309.00071), a technique for enhancing model length extrapolation, ensuring optimal performance on lengthy texts. |
|
|
|
For supported frameworks, you could add the following to `config.json` to enable YaRN: |
|
```json |
|
{ |
|
..., |
|
"rope_scaling": { |
|
"factor": 4.0, |
|
"original_max_position_embeddings": 32768, |
|
"type": "yarn" |
|
} |
|
} |
|
``` |
|
|
|
For deployment, we recommend using vLLM. |
|
Please refer to our [Documentation](https://qwen.readthedocs.io/en/latest/deployment/vllm.html) for usage if you are not familar with vLLM. |
|
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. |
|
|
|
## Evaluation & Performance |
|
|
|
Detailed evaluation results are reported in this [📑 blog](https://qwenlm.github.io/blog/qwen2.5-coder/). |
|
|
|
For requirements on GPU memory and the respective throughput, see results [here](https://qwen.readthedocs.io/en/latest/benchmark/speed_benchmark.html). |
