问题1：按照Rockchip_Developer_Guide_RockX_SDK_CN 文档，接入USB摄像头后，运行以下命令
python3 -m rockx.test.camera.rockx_object_detection
python3 -m rockx_object_detection.py
报以下错误：内存不够

问题2：通过chat-gpt搜索了解决答案，用sudo权限运行
sudo python3 -m rockx.test.camera.rockx_object_detection
sudo python3 -m rockx_object_detection.py
报以下错误：
ModuleNotFoundError: No module named ‘rockx’
3.参考文档和代码
