可以在文件顶部添加代码from typing import Any试试看
您好，问题是我把策略文件删了，删除之后还是输出这个log；加上from typing import Any还是输出这个log
1、添加策略至\vnstudio\Lib\site-packages\vnpy\app\cta_strategy\
2、进行cta回测，出现错误
3、删除策略
4、重启vnstation，
5、还是出现错误log
6、输出的log如下：
15:16:33 初始化CTA回测引擎
15:16:33 策略文件strategies.atr_demo_1加载失败，触发异常：

谢谢您，已解决，更改vnstudio\Lib\site-packages\vnpy\app\cta_backtester\ui\widget.py
self.chart.setMinimumWidth(800)调整参数即可

请先把屏幕分辨率改成1920x1080将缩放调好再试看看吧。若1080的分辨率仍显示不正常，缩放比例改成100%缩放试试看。
谢谢您的回答，我笔记本电脑分辨率是1366x768，改不了那么高，请问还有别的办法吗，感谢
1、向straregies中添加自己的策略出现bug
2、删除该策略文件
3、还是出现该bug的log
请问为什么策略文件删除了，还是输出bug的log
