In this blog post, we’ll walk you through setting up and using SaigaLlama3, an 8B Russian Llama-3-based chatbot. This chatbot relies on the Llama-3 model and is adaptable to various use cases, making it ideal for language processing tasks.
Getting Started with SaigaLlama3
To begin, make sure you have access to the required dependencies, including PyTorch and Hugging Face’s `transformers` library. Let’s get started with the installation and configuration of the model.
Installation
Before running your code, ensure your environment is ready. Here is an outline of how to set up the chatbot model:
- Ensure you have Python and pip installed.
- Install PyTorch and the transformers library by running:
pip install torch transformers
Using SaigaLlama3 Model
The following Python snippet demonstrates how to load the model and generate responses. Think of the code as a recipe for a cake. Each line of code represents an ingredient essential for the final product.
import torch
from transformers import AutoModelForCausalLM, AutoTokenizer, GenerationConfig
MODEL_NAME = "IlyaGusev/saiga_llama3_8b"
DEFAULT_SYSTEM_PROMPT = "Ты — Сайга, русскоязычный автоматический ассистент..."
model = AutoModelForCausalLM.from_pretrained(MODEL_NAME, load_in_8bit=True, torch_dtype=torch.bfloat16, device_map='auto')
model.eval()
tokenizer = AutoTokenizer.from_pretrained(MODEL_NAME)
generation_config = GenerationConfig.from_pretrained(MODEL_NAME)
inputs = ["Почему трава зеленая?", "Сочини длинный рассказ, обязательно упоминая следующие объекты. Дано: Таня, мяч"]
for query in inputs:
prompt = tokenizer.apply_chat_template([
{"role": "system", "content": DEFAULT_SYSTEM_PROMPT},
{"role": "user", "content": query}
], tokenize=False, add_generation_prompt=True)
data = tokenizer(prompt, return_tensors='pt', add_special_tokens=False)
data = {k: v.to(model.device) for k, v in data.items()}
output_ids = model.generate(**data, generation_config=generation_config)[0]
output_ids = output_ids[len(data['input_ids'][0]):]
output = tokenizer.decode(output_ids, skip_special_tokens=True).strip()
print(query)
print(output)
print("------------------------------")
In this recipe:
- Importing Libraries: Just like gathering ingredients, we import necessary modules.
- Model Import: The model is loaded using its name, like taking eggs from the fridge.
- Generating Prompt: We prepare the input prompt, similar to mixing your cake batter.
- Data Processing: Data transformations allow the model to digest the inputs.
- Model Generation: Finally, we bake our cake (generate the output) and print the delicious results.
Prompt Formats
Two different prompt formats are recognized by the SaigaLlama3 model:
- Original Llama-3 Format:
begin_of_text start_header_id system end_header_id Ты — Сайга, русскоязычный автоматический ассистент. end_header_id start_header_id user end_header_id Как дела? end_header_id start_header_id assistant end_header_id Отлично, а у тебя? end_header_id ...
- ChatML Format:
im_startsystem Ты — Сайга, русскоязычный автоматический ассистент. im_end im_startuser Как дела? im_end im_startassistant Отлично, а у тебя? im_end ...
Troubleshooting Tips
If you encounter issues while using SaigaLlama3, here are some suggestions:
- Ensure you have the correct versions of dependencies installed.
- Check that the model path and prompt formats align with the examples provided.
- Review any error messages for guidance on what might be wrong.
