Welcome to the realm of artificial intelligence! In this guide, we’ll dive into how to effectively download, use, and reproduce the powerful Llama3-8B-Chinese-Chat model, developed with the innovative Meta-Llama architecture.

1. Downloading the Model

To download the Llama3-8B-Chinese-Chat model, follow these steps:

• Visit the GitHub repository.
• Clone the repository to your local machine using the command:

git clone https://github.com/Shenzhi-Wang/Llama3-Chinese-Chat.git

• Navigate to the directory containing the models.

2. Utilizing the Model

Once downloaded, utilizing the model in your Python environment is straightforward. Here’s how to start:

from llama_cpp import Llama

# Initialize the model
model = Llama("/Your/Path/To/GGUF/File", verbose=False, n_gpu_layers=-1)

# Define the system prompt
system_prompt = "You are a helpful assistant."

# Function to generate a response
def generate_response(_model, _messages, _max_tokens=8192):
    _output = _model.create_chat_completion(
        _messages,
        stop=["<|eot_id|>", "<|end_of_text>"],
        max_tokens=_max_tokens,
    )["choices"][0]["message"]["content"]
    return _output

# Example usage
messages = [
    {
        "role": "system",
        "content": system_prompt,
    },
    {"role": "user", "content": "写一首诗吧"},
]

# Print the generated response
print(generate_response(model, messages))

This code is analogous to a chef preparing a meal based on specific recipes. The initial setup (like gathering ingredients) sets the foundation for your model. The messages passed in are akin to the instructions a chef receives on what dish to create. Finally, the response generated is the finished meal delivered to the customer!

3. Reproducing the Model

To reproduce the model, particularly Llama3-8B-Chinese-Chat-**v2**, execute the following command:

deepspeed --num_gpus 8 src/train_bash.py \
    --deepspeed ${Your_Deepspeed_Config_Path} \
    --stage orpo \
    --do_train \
    --model_name_or_path meta-llama/Meta-Llama-3-8B-Instruct \
    --dataset ${Your_Dataset_Name_or_PATH} \
    --template llama3 \
    --finetuning_type full \
    --output_dir ${Your_Output_Path} \
    --per_device_train_batch_size 1 \
    --per_device_eval_batch_size 1 \
    --gradient_accumulation_steps 8 \
    --learning_rate 5e-6 \
    --num_train_epochs 3.0 \
    --warmup_ratio 0.1 \
    --cutoff_len 8192 \
    --flash_attn true \
    --orpo_beta 0.05 \
    --optim paged_adamw_32bit

This step is akin to setting up a factory line where each phase has its specific job, significantly enhancing productivity!

Troubleshooting

If you encounter issues such as models not loading properly or unexpected errors, consider the following solutions:

• Ensure that your GPU drivers are updated and compatible with the version of the model you are using.
• Double-check the paths provided in your code to confirm they correctly point to the model files.
• Make sure all dependencies are correctly installed, and version conflicts are resolved.
• If you need further assistance, visit the community forums or contact developers for insights.
