Overview
Qwen2-Boundless is a fine-tuned model based on Qwen2-1.5B-Instruct, designed to answer various types of questions, including those involving ethical, illegal, pornographic, and violent content. This model has been specifically trained on a dataset that allows it to handle complex and diverse scenarios. It is important to note that the fine-tuning dataset is entirely in Chinese, so the model performs better in Chinese.
Warning: This model is intended for research and testing purposes only. Users should comply with local laws and regulations and are responsible for their actions.
How to Use
You can load and use the model with the following code:
from transformers import AutoModelForCausalLM, AutoTokenizerimport os device = "cuda" # the device to load the model ontocurrent_directory = os.path.dirname(os.path.abspath(__file__)) model = AutoModelForCausalLM.from_pretrained( current_directory, torch_dtype="auto", device_map="auto")tokenizer = AutoTokenizer.from_pretrained(current_directory) prompt = "Hello?"messages = [ {"role": "system", "content": ""}, {"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]print(response)
Continuous Conversation
To enable continuous conversation, use the following code:
from transformers import AutoModelForCausalLM, AutoTokenizerimport torchimport os device = "cuda" # the device to load the model onto # Get the current script's directorycurrent_directory = os.path.dirname(os.path.abspath(__file__)) model = AutoModelForCausalLM.from_pretrained( current_directory, torch_dtype="auto", device_map="auto")tokenizer = AutoTokenizer.from_pretrained(current_directory) messages = [ {"role": "system", "content": ""}] while True: # Get user input user_input = input("User: ") # Add user input to the conversation messages.append({"role": "user", "content": user_input}) # Prepare the input text text = tokenizer.apply_chat_template( messages, tokenize=False, add_generation_prompt=True ) model_inputs = tokenizer([text], return_tensors="pt").to(device) # Generate a response 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) ] # Decode and print the response response = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0] print(f"Assistant: {response}") # Add the generated response to the conversation messages.append({"role": "assistant", "content": response})
Streaming Response
For applications requiring streaming responses, use the following code:
import torchfrom transformers import AutoModelForCausalLM, AutoTokenizer, TextIteratorStreamerfrom transformers.trainer_utils import set_seedfrom threading import Threadimport randomimport os DEFAULT_CKPT_PATH = os.path.dirname(os.path.abspath(__file__)) def _load_model_tokenizer(checkpoint_path, cpu_only): tokenizer = AutoTokenizer.from_pretrained(checkpoint_path, resume_download=True) device_map = "cpu" if cpu_only else "auto" model = AutoModelForCausalLM.from_pretrained( checkpoint_path, torch_dtype="auto", device_map=device_map, resume_download=True, ).eval() model.generation_config.max_new_tokens = 512 # For chat. return model, tokenizer def _get_input() -> str: while True: try: message = input('User: ').strip() except UnicodeDecodeError: print('[ERROR] Encoding error in input') continue except KeyboardInterrupt: exit(1) if message: return message print('[ERROR] Query is empty') def _chat_stream(model, tokenizer, query, history): conversation = [ {'role': 'system', 'content': ''}, ] for query_h, response_h in history: conversation.append({'role': 'user', 'content': query_h}) conversation.append({'role': 'assistant', 'content': response_h}) conversation.append({'role': 'user', 'content': query}) inputs = tokenizer.apply_chat_template( conversation, add_generation_prompt=True, return_tensors='pt', ) inputs = inputs.to(model.device) streamer = TextIteratorStreamer(tokenizer=tokenizer, skip_prompt=True, timeout=60.0, skip_special_tokens=True) generation_kwargs = dict( input_ids=inputs, streamer=streamer, ) thread = Thread(target=model.generate, kwargs=generation_kwargs) thread.start() for new_text in streamer: yield new_text def main(): checkpoint_path = DEFAULT_CKPT_PATH seed = random.randint(0, 2**32 - 1) # Generate a random seed set_seed(seed) # Set the random seed cpu_only = False history = [] model, tokenizer = _load_model_tokenizer(checkpoint_path, cpu_only) while True: query = _get_input() print(f"\nUser: {query}") print(f"\nAssistant: ", end="") try: partial_text = '' for new_text in _chat_stream(model, tokenizer, query, history): print(new_text, end='', flush=True) partial_text += new_text print() history.append((query, partial_text)) except KeyboardInterrupt: print('Generation interrupted') continue if __name__ == "__main__": main()
Dataset
The Qwen2-Boundless model was fine-tuned using a specific dataset named bad_data.json, which includes a wide range of text content covering topics related to ethics, law, pornography, and violence. The fine-tuning dataset is entirely in Chinese, so the model performs better in Chinese. If you are interested in exploring or using this dataset, you can find it via the following link:
And also we used some cybersecurity-related data that was cleaned and organized from this file.
