# 程序执行出现libascendcl.so报错

#### 问题现象

程序在执行过程中出现如下报错：

```
error while loading shared libraries: libascendcl.so: cannot open shared object file: No such file or directory
```


#### 原因分析

“LD_LIBRARY_PATH”环境变量中CANN环境变量路径未正确配置。


#### 解决方案

请参考《CANN 软件安装指南(https://www.hiascend.com/document/detail/zh/canncommercial/700/envdeployment/instg/instg_0001.html)》配置CANN环境变量。
