How Do I Check the CANN Path in a ModelArts Notebook or on a Lite Server?

Querying via environment variables
Once CANN is installed, its environment variables are automatically configured. To find the installation location, check these variables. The primary one to look for is ASCEND_HOME_PATH. Open the terminal and run the following command:
```
echo $ASCEND_HOME_PATH
```
If the environment variable has been set, the CANN installation path is displayed.

Searching for files
If the environment variable is not set, you can run the find command to search for certain CANN files or directories in the system to determine the installation path. For example, search for the ascend-toolkit directory:
```
find / -name "ascend-toolkit" 2>/dev/null
```
This command searches for the ascend-toolkit directory from the root directory (/) and redirects error information to /dev/null to avoid unnecessary error information. The search may take some time, especially for large file systems.
