软件架构说明
## 快速开始
#### 安装教程 ```bash
# 1. 推理(对话)
python3 -c "
import json, torch
from llm_chat_improved import LLMModel, LLMChat, tokenizer_instance
1. xxxx vocab = json.load(open('vocab.json'))
2. xxxx ckpt = torch.load('llm_model_v2_resume_epoch_7.pth', map_location='cpu')
3. xxxx cfg = ckpt['model_config']
#### 使用说明 model = LLMModel(vocab_size=len(vocab), d_model=cfg['d_model'], n_heads=cfg['n_heads'],
n_layers=cfg['n_layers'], d_ff=cfg['d_ff'], max_len=cfg['max_len'], dropout=0.1)
model.load_state_dict(ckpt['model_state_dict'])
model.eval()
1. xxxx chat = LLMChat(model, vocab, device='cpu')
2. xxxx tokenizer_instance.char_to_id = vocab.copy()
3. xxxx tokenizer_instance.id_to_char = {v:k for k,v in vocab.items()}
#### 参与贡献 print(chat.generate_response('小狸你好呀'))
