smtp功能打开了

启动时没有勾选吧。或者你脚本启动没有添加其他功能

设置了SMTP交易后通知，每次交易后会出现这个错误:

请问是什么问题？

可以更新至最新版再试试看

好，这个是什么原因引起的？

刚开始运行是正常的，但是运行了几个小时后还是出现了如下报错，不知是什么原因，请哪位高手给解答一下，如何修复，感谢！

我是把2.7版本删掉卸载了，重新装的3.2版本。错误如下：

我好想知道了，我策略里加载模块的路径错误。要改一下，对吧。

升级到3.2版本，出现策略加载失败，如何解决：

arctic目前支持的python和pandas版本都比较旧，对python版本要求小于等于3.7，对pandas要求低于1.0.3。所以如果使用的python和pandas版本比较高的话建议降级，或者直接使用mongodb等适配的数据库。

谢谢，也就是说这个是数据库的问题，不影响实盘的交易是吧？

可以升级一下pandas试试

谢谢，升级了Pandas之后可以运行了，但是出现了下面的提示，说是有冲突。我是否也应该升级一下 vnpy-arctic1.0.1？

我用run.py开多窗口出现了问题，请问是什么问题？请哪位大神帮忙解决一下，图片如下：

感谢！

感谢大佬分享

出现这个问题，请问是什么导致的，怎么解决。

可以pip install --upgrade vnpy_ctastrategy试试

谢谢，按照这个方法已解决

是下载数据时报错，还是跑策略时报错？

跑策略的时候

升级到了2.6版本，设置是这样的。

启动策略的时候，要用历史数据，触发异常，报错如下：

[Test] 触发异常已停止

我也遇到类似的问题，启动策略的时候，要接入Rqdata历史数据的时候发生异常，还不知道怎么解决？

还有恒生期权API启动也是有问题的。截图如下：

只要勾选了火币期权这个底层端口，就会出现上面错误。

pip install vnpy_rest --upgrade
谢谢版主，升级了vnpy_rest --upgrade, 但是还是有问题，应该是火币gateway的问题，如果不勾选货币gateway就能正常启动了，勾选了火币接口就继续报错，错误如下：
