jetson orin nano安装环境
更新软件、安装pip3 配置源等
下载软件
sudo apt install python3-pip nano -ysudo -H pip3 install jetson-statssudo apt-get install libopenblas-devsudo jtop 查看jetpack版本设置pip源
mkdir -p ~/.pipnano ~/.pip/pip.conf安装cuda
sudo apt-get install python3-pip -yrebootjtopsudo apt install nvidia-jetpacksudo vim ~/.bashrc 添加
export PATH=/usr/local/cuda/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda/lib64:$LD_LIBRARY_PATH更改cuda为11.7

安装paddlepaddle
paddle下载地址
pip install paddlepaddle_gpu-2.4.2-cp38-cp38-linux_aarch64.whl安装yolo8、torch-gpu
pip install ultralytics==8.1.0pip uninstall torchpip uninstall torchvisionsudo apt-get install libopenblas-devpip install torch-2.1.0a0+41361538.nv23.06-cp38-cp38-linux_aarch64.whl安装torchvision
cd visionexport BUILD_VERSION=0.16.0python3 setup.py install --user注意torch和torchvision的对应关系，安装ultralytics时可能覆盖安装torch和torchvision，需重新安装torchvision
pip install torchvision==0.16.0已验证版本：
| jetpack | cuda | cudnn | paddlepaddle | yolo | torch | torchvision |
|---|---|---|---|---|---|---|
| 5.1.4 | 11.4 | 8.6 | 2.4.2 | 8.1.0 | 2.1.0 | 0.16.0 |
| 5.1.2 | 忘记 | 忘记 | 2.4.2 | 8.1.0 | 2.0.0 | 0.15.1 |
