python - http localhost 5000 tasks出现500错误

Question

系统win10 ，装了anaconda3环境 用的是python3 pyspider0.3.7
webui点击recent active tasks显示

<code>Internal Server Error

The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.
</code>

然后命令行显示如下错误，求助，非常感谢！
