TX2配置yolov5环境

TX2系统版本：

lsb_release -a

No 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：
