+# 流式输出操作手册
+
+# 环境安装
+docker 路径：
+
+由于流式输出需要特定的环境依赖，因此在新的env下进行推理和输出
+conda activate stream_info
+
+# 流程：
+1 将模型进行convert处理，将训练模型转换成流式输出支持的格式
+   python convert.py
+
+2 模型推理: python deploy_llm_8b_demo.py
+   (1) 设置CUDA_VISIBLE_DEVICES的数目
+   (2) 修改LocalLoader 中的实际使用模型的属性
+   (3) 在修改LocalLoader调用的时候，修改流式输出模型位置及其词表
+
+3 测试请求：python request_demo.py
+  若不清楚请求的ip port，可以在推理阶段保存的log文件（error_8b.log）中找到
