增加的功能需要在常用对话中添加

原有的功能需要保持没有问题

donghaiwang · 2026-06-28T03:43:38Z


        # 车辆相关关键词
        vehicle_keywords = ['车', '车辆', '汽车', '生成车', '创建车', '来车', '加车', '添加车辆']
-        # 行人相关关键词（更精确，避免误判）


之前的注释一般不删除，删除的话需要说明下，后面类似的都是

更新在这个链接 445b51f#diff-4097ce67660ec817eb94bf18dc878509f1f6bb42a184ddbe00c8e53b496a0fc0

修改的内容为页面显示的改变，而不是所提到的注释的删除

donghaiwang · 2026-07-02T02:55:27Z

前面提到的3个问题都没有解决或者回复

直接运行mcp.bat后，在浏览器点击第一个指令
提示没有成功：

Dame-time-0034 · 2026-07-02T12:36:08Z

在本设备中是使用cmd打开的FastMCP，可以正常运行，如上图所示。按钮会按要求修改

donghaiwang · 2026-07-02T12:41:15Z

点击第二个按钮后，后台输出为：

错误信息为：

还需要解决这个问题，保证在其他电脑上能够运行。或者提供解决的思路，我来测试

donghaiwang · 2026-07-02T12:53:35Z

确认下，看是不是mcp版本的问题，现在 mcp.bat 启动所使用的 python 版本为 3.10 （dependencies\prerequisites\miniconda3\envs\hutb_3.10），mcp的版本为2.14.5
看你开发使用的是不是这个版本

Dame-time-0034 · 2026-07-02T14:59:20Z

对的，版本不一致。这是我开发分别使用的版本号，分别是mcp：1.27.2 Python： 3.11.9
请问下一步需要如何操作呢

Dame-time-0034 · 2026-07-02T15:08:44Z

这是更新后一个按钮的页面

donghaiwang · 2026-07-03T01:02:51Z

使用运行mcp.bat下载的dependencies\prerequisites\miniconda3\envs\hutb_3.10进行开发和测试。
或者切换到本地安装的python 3.10 进行测试，并指定安装mcp的版本为2.14.5，看是否能够正常运行

donghaiwang · 2026-07-03T01:15:24Z

不能把之前的功能对话给删掉了

Dame-time-0034 · 2026-07-03T02:00:23Z

我已把python版本切换到3.10，但是双击mcp.bat无法打开模拟器，电脑提示如图所示

donghaiwang · 2026-07-03T04:17:45Z

在某些机器上不能运行都算bug，可以后面再修复，先保证在自己建立的python3.10上测试通过

Dame-time-0034 · 2026-07-03T15:38:48Z

在我的计算机上python3.10无论如何也打不开mcp，python3.11可以，以下是终端

donghaiwang · 2026-07-03T23:42:42Z

先看报错信息，已经提示了，ModuleNotFoundError: No module named 'fastapi'，需要安装fastapi的包

FastMCP2.14.5+python3.10没有问题了，但这两个配合起来兼容性有点差，修改了一些文件，路径和修改内容如下
1.C:\Users\xiaoyi\AppData\Local\Programs\Python\Python310\lib\site-packages\fastmcp\mcp_config.py

在文件最后（update_config_file 函数之后），添加：
python
def _coerce_tool_transform_configs(configs):
"""Coerce tool transform configs to a list of dictionaries.
这是一个临时修复函数，用于兼容 fastmcp 2.14.5。
"""
if configs is None:
return []
if isinstance(configs, list):
return configs
if isinstance(configs, dict):
return [configs]
# 如果是 ToolTransformConfig 对象
if hasattr(configs, 'model_dump'):
return [configs.model_dump()]
return []

2.C:\Users\xiaoyi\AppData\Local\Programs\Python\Python310\lib\site-packages\fastmcp\exceptions.py

在文件末尾添加缺失的类
python
class FastMCPDeprecationWarning(DeprecationWarning):
"""Warning for deprecated FastMCP features."""
pass

3.C:\Users\xiaoyi\AppData\Local\Programs\Python\Python310\lib\site-packages\fastmcp\client\transports_init_.py

在文件末尾的 all 之前添加：
python
from fastmcp.client.transports.ws import WSTransport

并在 all 中添加 "WSTransport"：
python
all = [
"ClientTransport",
"FastMCPStdioTransport",
"FastMCPTransport",
"NodeStdioTransport",
"NpxStdioTransport",
"PythonStdioTransport",
"SSETransport",
"StdioTransport",
"StreamableHttpTransport",
"UvStdioTransport",
"UvxStdioTransport",
"WSTransport", # 新增
"infer_transport",
]

创建 ws.py 文件（如果不存在）

C:\Users\xiaoyi\AppData\Local\Programs\Python\Python310\lib\site-packages\fastmcp\client\transports\ws.py
添加内容：

python
"""WebSocket transport for FastMCP client."""

from typing import Any

from fastmcp.client.transports.base import ClientTransport

class WSTransport(ClientTransport):
"""WebSocket transport for MCP client."""

def __init__(self, url: str, headers: dict[str, str] | None = None):
    self.url = url
    self.headers = headers or {}

async def connect(self):
    """Connect to the WebSocket server."""
    pass

async def send(self, message: Any):
    """Send a message over WebSocket."""
    pass

async def receive(self):
    """Receive a message over WebSocket."""
    pass

async def close(self):
    """Close the WebSocket connection."""
    pass

最后直接运行我修改过的main ai.py文件就可以了

donghaiwang · 2026-07-04T04:36:06Z

调用成功了，但是没找到sumo。看是不是mcp.bat中设置环境变量没有生效。注意：默认需要使用的是`mcp\hutb\sumo`目录下的sumo软件

donghaiwang

将SUMO_HOME的设置改为默认的hutb\sumo下的软件的保存路径即可

set "SUMO_HOME=%PROJECT_ROOT%\hutb\sumo"

donghaiwang · 2026-07-04T04:52:07Z

 set "VIRTUAL_ENV=%VENV_PATH%"

+REM ===== 设置 SUMO_HOME（相对路径） =====
+set "SUMO_HOME=%PROJECT_ROOT%\sumo\sumo_install\sumo-win64-1.27.0\sumo-1.27.0"


Suggested change

set "SUMO_HOME=%PROJECT_ROOT%\sumo\sumo_install\sumo-win64-1.27.0\sumo-1.27.0"

set "SUMO_HOME=%PROJECT_ROOT%\hutb\sumo"
