AI CPU算子Kernel执行报错

现象描述

Runtime执行报错，在plog日志中Runtime打印了PrintAicpuErrorInfo的错误信息。

plog日志默认在$HOME/ascend/log/[run|debug]/plog路径下，日志格式为plog-pid_yyymmddhhmmss.log。

可能原因

从日志报错可知，AI CPU算子执行失败，可能算子本身代码问题：数据输入不匹配（例如数据格式、广播维度（部分基于TensorFlow实现的算子不支持大于6维的广播）等）、访问越界、AI CPU线程挂死、算子执行超时（默认不超过30秒）等问题。

比如通过查阅AI CPU的device日志，排查具体报错原因。

device日志默认在$HOME/ascend/log/[run|debug]/device-id路径下，日志格式为device-pid_yyymmddhhmmss.log。

  • 样例1：UniqueExt算子输入数据维度不符合要求。
