Posted 2021-07-08 FL1623863129

 1. Jetpack默认已安装opencv、cuda、cudnn，故只需再安装pytorch即可，留意jetson是arm架构，需要下载对应的安装文件加以安装
 2. pytorch的安装
  查询Jetpack的版本

sudo -H pip3 install jetson-stats
jetson_release
  pytorch的whl文件下载（注意与Jetpack的版本相匹配）网址链接：https://forums.developer.nvidia.com/t/pytorch-for-jetson-nano-version-1-6-0-now-available/72048
安装pytorch的whl命令（注意whl文件名应跟自己下载的一致）
pip3 install torch-1.4.0-cp36-cp36m-linux_aarch64.whl
若在import torch中出现了numpy相关的安装问题，如ModuleNotFoundError: No module named ‘numpy.core._multiarray_umath’
键入下面命令解决
pip3 install --upgrade numpy
若在import torch中出现了mpi相关的问题
键入下面命令解决
sudo apt-get install openmpi-bin
 3. torchvision的安装

sudo apt-get install libjpeg-dev zlib1g-dev
git clone --branch v0.5.0 https://github.com/pytorch/vision torchvision   # see below for version of torchvision to download
cd torchvision
sudo python setup.py install
cd ../  # attempting to load torchvision from build dir will result in import error
