我将两级条件分支节点之后的知识检索节点全部聚合在一个聚合变量节点，送入LLM节点，LLM节点无法流式输出，在LLM全部计算完毕后全部一次性显示，<深度思考>显示为0s，但<深度思考>实际有内容。使用ollama调用本地大模型。已排除其他原因，原因已锁定在“两级条件分支节点之后的知识检索节点全部聚合在一个聚合变量节点，送入LLM节点”。
Aggregate all knowledge retrieval nodes following the two-level conditional branch structure into a single variable node, then pass it to the LLM node. The LLM node cannot stream outputs and displays results entirely upon completion. The shows 0s duration but contains actual content.Using ollama to invoke the local LLM. After ruling out other potential causes, the issue has been isolated to the process of aggregating all knowledge retrieval nodes following the two-level conditional branch structure into a single variable node before passing to the LLM node.
