## Inference String Format The inference string is a concatenated string formed by combining conversation data(system, human and bot contents) in the training data format. It is used as input during the inference process. Here are examples of prompts used to request the model: **Multi-Round with System Prompt:** ```python """ system System instruction human Human 1st round input bot Bot 1st round output<｜end▁of▁sentence｜> human Human 2nd round input bot Bot 2nd round output<｜end▁of▁sentence｜> ... ... ... human Human nth round input bot """ ``` **Single-Round without System Prompt:** ```python """ human User prompt... bot """ ``` In this format, the system section is optional and the conversation can be either single-turn or multi-turn. When applying inference, you always make your input string end with "\bot" to ask the model generating answers. ## Quickstart ```python import torch from transformers import AutoTokenizer, AutoModelForCausalLM, GenerationConfig def load_model_tokenizer(model_path): tokenizer = AutoTokenizer.from_pretrained("codefuse-ai/CodeFuse-DeepSeek-33B", trust_remote_code=True, use_fast=False, legacy=False) tokenizer.eos_token = "<｜end▁of▁sentence｜>" tokenizer.pad_token = "<｜end▁of▁sentence｜>" tokenizer.eos_token_id = tokenizer.convert_tokens_to_ids(tokenizer.eos_token) tokenizer.pad_token_id = tokenizer.convert_tokens_to_ids(tokenizer.pad_token) tokenizer.padding_side = "left" model = AutoModelForCausalLM.from_pretrained(model_path, device_map='auto',torch_dtype=torch.bfloat16, trust_remote_code=True) return model, tokenizer HUMAN_ROLE_START_TAG = "human\n" BOT_ROLE_START_TAG = "bot\n" model_dir = snapshot_download('codefuse-ai/CodeFuse-DeepSeek-33B', revision='v1.0.0') text_list = [f'{HUMAN_ROLE_START_TAG}请写一个快排程序\n#Python\n{BOT_ROLE_START_TAG}'] model, tokenizer = load_model_tokenizer(model_dir) inputs = tokenizer(text_list, return_tensors='pt', padding=True, add_special_tokens=False).to('cuda') input_ids = inputs["input_ids"] attention_mask = inputs["attention_mask"] generation_config = GenerationConfig( eos_token_id=tokenizer.eos_token_id, pad_token_id=tokenizer.pad_token_id, temperature=0.2, max_new_tokens=512, num_return_sequences=1, num_beams=1, top_p=0.95, do_sample=False ) outputs = model.generate( inputs= input_ids, attention_mask=attention_mask, **generation_config.to_dict() ) gen_text = tokenizer.batch_decode(outputs[:, input_ids.shape[1]:], skip_special_tokens=True) print(gen_text[0]) ``` ## 模型简介 CodeFuse-DeepSeek-33B 是一个通过QLoRA对基座模型DeepSeek-Coder-33B进行多代码任务微调而得到的代码大模型。

## 推理数据格式 推理数据为模型在训练数据格式下拼接的字符串形式，它也是推理时输入prompt拼接的方式. 下面分别是带系统提示的多轮会话格式和不带系统提示的单轮会话格式： **带System提示的多轮会话格式:** ```python """ system System instruction human Human 1st round input bot Bot 1st round output<｜end▁of▁sentence｜> human Human 2nd round input bot Bot 2nd round output<｜end▁of▁sentence｜> ... ... ... human Human nth round input bot """ ``` **不带System提示的单轮会话格式:** ```python """ human User prompt... bot """ ``` 在这个格式中，System提示是可选的（按需设定），支持单轮会话也支持多轮会话。推理时，请确保拼接的prompt字符串以"\bot\n"结尾，引导模型生成回答。 ## 快速使用 ```python import torch from transformers import AutoTokenizer, AutoModelForCausalLM, GenerationConfig def load_model_tokenizer(model_path): tokenizer = AutoTokenizer.from_pretrained("codefuse-ai/CodeFuse-DeepSeek-33B", trust_remote_code=True, use_fast=False, legacy=False) tokenizer.eos_token = "<｜end▁of▁sentence｜>" tokenizer.pad_token = "<｜end▁of▁sentence｜>" tokenizer.eos_token_id = tokenizer.convert_tokens_to_ids(tokenizer.eos_token) tokenizer.pad_token_id = tokenizer.convert_tokens_to_ids(tokenizer.pad_token) tokenizer.padding_side = "left" model = AutoModelForCausalLM.from_pretrained(model_path, device_map='auto',torch_dtype=torch.bfloat16, trust_remote_code=True) return model, tokenizer HUMAN_ROLE_START_TAG = "human\n" BOT_ROLE_START_TAG = "bot\n" model_dir = snapshot_download('codefuse-ai/CodeFuse-DeepSeek-33B', revision='v1.0.0') text_list = [f'{HUMAN_ROLE_START_TAG}请写一个快排程序\n#Python\n{BOT_ROLE_START_TAG}'] model, tokenizer = load_model_tokenizer(model_dir) inputs = tokenizer(text_list, return_tensors='pt', padding=True, add_special_tokens=False).to('cuda') input_ids = inputs["input_ids"] attention_mask = inputs["attention_mask"] generation_config = GenerationConfig( eos_token_id=tokenizer.eos_token_id, pad_token_id=tokenizer.pad_token_id, temperature=0.2, max_new_tokens=512, num_return_sequences=1, num_beams=1, top_p=0.95, do_sample=False ) outputs = model.generate( inputs= input_ids, attention_mask=attention_mask, **generation_config.to_dict() ) gen_text = tokenizer.batch_decode(outputs[:, input_ids.shape[1]:], skip_special_tokens=True) print(gen_text[0]) ```
