# AI CPU算子维度超过8维报错

#### 问题现象

GE执行报错，在应用程序运行日志中GE打印了ReportErrMessage的错误信息，且提示“shape dim num should be less than 8”。

Ascend EP 形态，应用程序运行日志默认在$HOME/ascend/log/[run|debug]/plog路径下，日志文件为plog-pid_*.log。

Ascend RC 形态，应用程序运行日志默认在$HOME/ascend/log/[run|debug]/device-app-pid路径下，日志文件为device-app-pid_*.log。

```


#### 可能原因

AI CPU算子输入/输出参数的维度超过最大维度限制（8维）。


#### 解决方法

根据报错信息修改算子参数输入/输出维度，确保不超过8维。
