vLLM本地部署 Seed-OSS-36B-Instruct 并通过修改chat_template.jinja模板实现思考与非思考切换

设备：4卡 Tesla T10
模型：cpatonn/Seed-OSS-36B-Instruct-AWQ-8bit
推理框架docker版vLLM：vllm-openai:nightly-8f8fda261a620234fdeea338f44093d5d8072879

实现思考预算设置可以看我上一个博客：https://blog.csdn.net/oTianShiYeDiaoMao123/article/details/155322503

这是第二个版本的jinja模板，修改如下：

• 去除了jinja模板中的与思考预算相关的部分，个人使用过程中发现思考预算用处不大。
• 现在只有思考和非思考模式，当在系统提示词中加入“seed_oss_no_reasoning”就会切换为非思考模式。
• 非思考模式下会自动去除系统提示词中的“seed_oss_no_reasoning”字段，保留系统提示词的其它部分，也就是非思考模式下也能用系统提示词了（第一版jinja模板不行）。

第一次创建容器后，执行以下命令，解决非思考模式下使用非流式输出时的bug（这个bug在第一版jinja文件修改的博客中有提到）

dockerexec-it seedsed-i's/return model_output, None/return None, model_output/'/usr/local/lib/python3.12/dist-packages/vllm/reasoning/basic_parsers.py
