TX2配置yolov5环境
TX2系统版本：
lsb_release -aNo LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 18.04.6 LTS Release: 18.04 Codename: bionic更新系统和包：
sudo apt-get update sudo apt-get upgrade安装Archiconda3
Archiconda下载地址
下载好使用ftp或者其他工具拖进去 cd进入目录运行下面命令
bash Archiconda3-0.2.3-Linux-aarch64.sh根据提示输入yes或者enter 会自动添加路径，如果最后没有按yes需要手动添加archiconda的安装路径到bashrc
测试：source archiconda3/bin/activate
退出：source deactivate
可能会存在每次打开都是默认进入base环境，需要在bashrc里面添加一条语句：
source deactivate创建运行yolov5的虚拟环境
conda create -n yolov5_py36 python=3.6 #创建一个python3.6环境
conda info --envs # 查看所有环境
conda activate yolov5_py36 #进入环境
conda deactivate # 退出环境
换源
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/ conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/msys2/ conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/pytorch/
安装一些包和库
sudo apt-get dist-upgrade sudo apt-get install python3-pip libopenblas-base libopenmpi-dev进入我们的yolov5运行环境
conda activate yolov5_py36 pip3 install --upgrade pip #如果pip已是最新，可不执行 上述命令会报错可用下面的命令换源更新：pip3 install -i https://pypi.tuna.tsinghua.edu.cn/simple --upgrade pip安装pytorch和torchvison（最重要的地方）
查看JetPack版本：
sudo apt-cache show nvidia-jetpack
1）安装pytorch不仅需要查看python版本也需要查看JetPack版本
2）因为python3.8需要安装的Pytorch都是在JetPack5上安装的，而jetson TX2的
JetPack是4.6.4-b39，所以配置yolov5的环境需要使用python3.6，整体的环境是
JetPack4.6.4-b39---Python3.6---PyTorch1.8（torch1.8_aarch64)，
PyTorch可选版本在1.10-1.0之间，如果是JetPack5以上，那么可选的PyTorch在1.11-2.1之间。
版本对应连接，下载地址：PyTorch for Jetson - Jetson & Embedded Systems / Jetson Nano - NVIDIA Developer Forums
下载PyTorch1.8（torch1.8_aarch64)

安装
安装pytorch 进入我们的yolov5运行环境
conda activate yolov5_py36
然后找到下载好的torch-1.8.0-cp36-cp36m-linux_aarch64.whl包的所在文件夹，
进入文件夹中，输入安装命令：
pip3 install torch-1.8.0-cp36-cp36m-linux_aarch64.whl #注意安装包的位置
测试报错：

报错原因：
ls /path/to/libcurand.so.10
结果显示文件不存在所以是没有安装 可能需要安装或重新安装CUDA Toolkit和cuDNN库，这是Torch所需的
安装cuda
/usr/local/cuda/version.txt
显示没安装cuda

里面安装文件移动cuda10.2权限不够，需要线移到其他文件，然后cd到目标文件下 ：
sudo mv 目标文件 /usr/local/
测试报错：

报错解决
安装torchvision
进入trochvision文件夹中， 执行命令：
export BUILD_VERSION=0.9.0
然后执行安装命令：
python setup.py install
等待等待，需要比较长时间
install报错：
