调用jaseci.walker_yield_delete删除talk walker yield时提示找不到

报错Walker talk not found!的核心原因是调用jaseci.walker_yield_delete时使用了不完整的walker标识符。Jaseci中需要通过完整的命名空间（如walker::talk）定位walker，仅用"talk"无法匹配到正确的walker实例。

1. 使用完整的walker限定名 #

将jaseci.walker_yield_delete("talk")修改为完整的walker路径：

jaseci.walker_yield_delete("walker::talk");

如果talk walker是从tesla_ai.jac模块导入且模块有自定义命名空间（比如导入时用import {*} as tesla with './tesla_ai.jac'），则需要用tesla::walker::talk作为参数。

2. 调整调用时机（优化建议） #

建议在每个flow开始前执行删除操作，确保新flow的初始状态完全干净：

for flow in flows {
    // 先清除上一轮的yield实例
    jaseci.walker_yield_delete("walker::talk");
    std.log("\n==== Testing flow: " + flow["test_name"] + " ====");

    // 后续step逻辑...
}

3. 结合报告清除（彻底避免残留） #

如果需要彻底消除旧响应的干扰，在每个flow开始时同时清除报告数据：

for flow in flows {
    jaseci.walker_yield_delete("walker::talk");
    std.clear_report(); // 清空历史报告
    std.log("\n==== Testing flow: " + flow["test_name"] + " ====");

    // 后续step逻辑...
}

4. 容错处理（可选） #

如果不确定是否存在待删除的yield实例，可添加try-catch避免测试中断：

try {
    jaseci.walker_yield_delete("walker::talk");
} catch e {
    std.log("No existing talk walker yield to delete: ", e);
}

import {*} with './tesla_ai.jac';
import {*} with './graph.jac';
import {*} with './nodes.jac';

walker nothing {}

test "Testing Flow"
with graph::tesla_ai by walker::nothing{
    flows = file.load_json("master_test.json");
    
    for flow in flows {
        // 清除上一轮的yield实例和报告
        try {
            jaseci.walker_yield_delete("walker::talk");
        } catch e {
            std.log("No talk walker yield to clean up: ", e);
        }
        std.clear_report();

        std.log("\n==== Testing flow: " + flow["test_name"] + " ====");

        for step in flow['flow'] {
            spawn here walker::talk(question = step["query"]);

            res = std.get_report();

            std.log("HERE >>> ", step["query"] , " ==== ", res[-1]);

            assert(res[-1] == step['response']);  

        }
    }
}
