新手求组:关于启动后及点击CTA回测出现的一些报错，自己水平有限，查阅资料都没有解决问题，才上来到论坛求组：
第一个是：点击启动后出现：
please migrate to a new time zone provider. For more details on how to do so .......报错
我将 C:\veighna_studio\Lib\site-packages\vnpy\trader\setting.py 变成 "database.timezone": 'Asia/Shanghai'
报错消失，但不知道是否有后续影响
第二个是：点击CTA回测，进入回测界面后,出现以下报错：
vnpy_ctastrategy.strategies.tempCodeRunnerFile加载失败，触发异常：
Traceback (most recent call last):
File "C:\veighna_studio\lib\site-packages\vnpy_ctabacktester\engine.py", line 110, in load_strategy_class_from_module

第三个是：将自编的CTA策略放入文件夹后，点击CTA回测，不进进入，出现对话框，报错：

麻烦、辛苦论坛大神给予提示，我没有办法解决。。。。。
