```
  Result:
```
Location: /usr/local/lib64/python3.9/site-packages
```
  Note:
  The actual output depends on how the application is installed.
2. Execute the following to enter the directory, for example, /usr/local/lib64/python3.9/site-packages as indicated in the previous step output:
```
cd /usr/local/lib64/python3.9/site-packages
```
3. Execute the following command to enter the sample-code directory:
```
cd ./VisionFive/sample-code/
```
Under the sample-code directory, execute the following command to execute the demo code:
```
