用的hdf5。请问你用数据库的情况下解决了么?
噢噢,那咱俩应该不是一个问题,我试过手动释放hdf5文件的句柄,没有效果。还是感谢兄弟~
还好,就是多写段处理h5的代码。存数据库是不是得挤爆啊,之前想过用数据库,但是这样得把数据库挤爆吧....
@xujun05 老哥,请问你本地回测的速度是多快呢?用的什么数据库呢?我把缓存爆炸的问题解决了,现在问题在IO上,一半时间耗在h5上,速度比rqalpha线上回测还慢了50%的样子。想换数据库试试。 谢谢了!
只要初始化的时候设置url为空字符串,用到的时候再绑定就可以了。
@RipperTs 再加个v-if即可
I tries to make learning rate smaller, but it seems that the performance gets worse. Therefore, I don't think learning rate is the issue here.
I think the model learns something, but that something doesn't reflect by the rewards. I wonder why is that.
