How to Get Started with the QwenQwen2.5-3B-Instruct Model

The QwenQwen2.5-3B-Instruct model, developed by hack337, is a sophisticated text generation model designed to assist in creating human-like text through advanced computational algorithms. In this guide, we’ll walk you through the steps to successfully implement this model, whether you’re using a GPU or an NPU.

Model Details

The QwenQwen2.5-3B-Instruct model is fine-tuned from QwenQwen2.5-3B-Instruct, making it an efficient choice for generating text. It aims to provide intuitive responses in various scenarios. The model is licensed under Apache-2.0, ensuring that it can be freely used with the required considerations.

How to Get Started with the Model

Follow these simple steps to utilize the QwenQwen2.5-3B-Instruct model effectively:

Using the Model with a GPU

Here’s a sample code snippet to get you started:

python
from transformers import AutoModelForCausalLM, AutoTokenizer

device = cuda  # the device to load the model on
model = AutoModelForCausalLM.from_pretrained(
    "Hack337/WavGPT-1.5",
    torch_dtype=auto,
    device_map=auto
)
tokenizer = AutoTokenizer.from_pretrained("Hack337/WavGPT-1.5")

prompt = "Give me a short introduction to large language model."
messages = [
    {"role": "system", "content": "Вы очень полезный помощник."},
    {"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]

Using the Model with an NPU

If you’re working with an NPU, use the following code:

python
from transformers import AutoTokenizer, TextStreamer
from intel_npu_acceleration_library import NPUModelForCausalLM
import torch

# Load the NPU-optimized model without LoRA
model = NPUModelForCausalLM.from_pretrained(
    "Hack337/WavGPT-1.5",
    use_cache=True,
    dtype=torch.float16  # Use float16 for the NPU
).eval()

# Load the tokenizer
tokenizer = AutoTokenizer.from_pretrained("Hack337/WavGPT-1.5")
tokenizer.pad_token_id = tokenizer.eos_token_id
streamer = TextStreamer(tokenizer, skip_special_tokens=True)

# Prompt handling
prompt = "Give me a short introduction to large language model."
messages = [
    {"role": "system", "content": "Вы очень полезный помощник."},
    {"role": "user", "content": prompt}
]

# Convert to a text format compatible with the model
text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
prefix = tokenizer([text], return_tensors=pt)["input_ids"].to(npu)

# Generation configuration
generation_kwargs = dict(
    input_ids=prefix,
    streamer=streamer,
    do_sample=True,
    top_k=50,
    top_p=0.9,
    max_new_tokens=512,
)

# Run inference on the NPU
print("Run inference")
_ = model.generate(**generation_kwargs)

Analogous Explanation of the Code

Think of the QwenQwen2.5-3B-Instruct model as a highly skilled chef in a kitchen. The process of preparing a meal (or generating text) starts with gathering ingredients (the code). First, you introduce the chef to the kitchen (loading the model and tokenizer). Next, you give the chef the recipe (the prompt) and set the stage (the messages) to ensure they understand what dish (response) to prepare. The transformation of ingredients into a delicious meal corresponds to the model processing the input and generating a coherent output. Lastly, you present the prepared dish (the generated text) ready for enjoyment!

Troubleshooting Ideas

While working with the QwenQwen2.5-3B-Instruct model, you might encounter a few challenges. Here are some troubleshooting ideas:

• Issue: Model fails to load.
• Solution: Check your internet connection and ensure you have the correct model repository link.
• Issue: Incomplete or garbled output.
• Solution: Review the prompt given to the model and ensure it follows the expected format.
• Issue: High memory usage leading to crashes.
• Solution: Try reducing the batch size or simplifying the model configuration.
