1. 源由

鑒于之前NVIDIA提供基于JetPack v5.1.4二進制pytorch版本最高為 v2.1.0。

經過不斷地各方努力，《Linux 35.6 + JetPack v5.1.4之編譯 pytorch》，我們已經有了python3.8.0的 pytorch v2.4.1.

2. 升級

步驟1：獲取二進制版本

$ wget https://github.com/SnapDragonfly/pytorch/releases/download/v2.3.1%2Bl4t35.6-cp38-cp38-aarch64/torch-2.3.1+l4t35.6-cp38-cp38-linux_aarch64.whl

步驟2：安裝二進制版本

$ sudo pip3 install torch-2.3.1+l4t35.6-cp38-cp38-linux_aarch64.whl

步驟3：獲取torchvision

$ git clone https://github.com/SnapDragonfly/vision.git torchvision
$ cd torchvision
$ git checkout nvidia_v0.19.1

步驟4：安裝torchvision

$ export BUILD_VERSION=0.19.1
$ sudo python3 setup.py install --user
$ cd ..

步驟5：檢查安裝版本

$ git clone https://github.com/SnapDragonfly/jetson-fpv.git
$ cd jetson-fpv
$ sudo ./wrapper.sh version

3. 使用

略，參考《Ardupilot開源無人機之Geek SDK討論》

• SnapDragonfly/jetson-fpv

$ cd jetson-fpv
$ sudo ./wrapper.sh dsyolo start

4. 補充

4.1 torchvision版本問題

若仍然使用之前NVIDIA安裝 v2.1.0 版本對應的 torchvision v0.16.1 或者 0.16.2 則會出現以下報錯！

4.2 支持pytorch版本

目前，支持4個pytorch版本：

• Release pytorch-v2.4.1+l4t35.6-cp38-cp38-aarch64
• Release pytorch-v2.3.1+l4t35.6-cp38-cp38-aarch64
• Release pytorch_v2.2.2+l4t35.6-cp38-cp38-aarch64
• Release pytorch_v2.1.2+l4t35.6-cp38-cp38-aarch64

4.3 opencv-python>=4.6.0問題

實際筆者環境是OpenCV4.9.0，但是還是報錯；而使用python代碼沒有問題。
