    又出现其他错误?快来看看啊

    (iQuant) #3

    这个您可以先不用缓存重新跑一边,应该也是模块长时间不用缓存被清了,先试一下。


    (mefan) #4

    同上 第三天了… “模块长时间不用缓存被清”不成立
    OSError: /var/app/data/bigquant/datasource/user/v3/3/24/324ea7abf84c47dd81647eba7f7c1ec0/all.h5 does not exist


    (iQuant) #5

    就是应该缓存被清理了,没有命中缓存,您先不使用缓存,重新跑一下试试。


    (mefan) #6

    是在滚动训练里的 几个时间段里跑着就出现某时间 又不是固定时段 您是怎么确定我们就用缓存的


    (iQuant) #7

    就是之前缓存的文件保存在上面那个位置,您运行策略过程中某个环节去提取文件没有成功,会报这个错,您先取消勾选使用缓存,重新运行试一下。


    (tkyz) #8

    全部取消缓存,重启内核都不行。
