前日给jetson nano安装jetson-inference时，
jetbot突然OLED屏幕黑了，重启之后不曾想竟不管用…
于是寻方觅法，无解…
遂重装Ubuntu系统，重装两次，问题得以解决

来回耽搁两日，今日终于完成，在这里将易忘的过程记录。

  1. 当需要从GitHub上clone项目时，可先将项目导入到gitee上，再进行clone，即可满速下载

  2. 在执行 “git submodule update –init” 时，命令行卡在 “正克隆到…” 很长时间，这时将进程停止，文件中有克隆的文件夹，但为空，此时执行后面的命令，当cmake出现错误时，将空文件夹删掉，再进行 “git submodule update –init” 即可克隆文件。

  3. 下载模型和pytorch时，可进行换源后下载，在 “/jetson-inference/tools” 下执行如下命令： 

$sed -in-place -e 's@https://nvidia.box.com/shared/static@https://bbs.gpuworld.cn/mirror@g' download-models.sh   
安装pytorch换源：   
$sed -in-place -e 's@https://nvidia.box.com/shared/static@https://bbs.gpuworld.cn/mirror@g' install-pytorch.sh   
$sed -in-place -e 's@https://github.com/pytorch/vision@https://gitee.com/vcan123/pytorch@g' install-pytorch.sh   
$sed -in-place -e 's@https://github.com/dusty-nv/vision@https://gitee.com/vcan123/dusty-nv@g' install-pytorch.sh
  1. pytorch也可以下载好.whl文件使用 “sudo pip3 install torch-1.6.0-cp36-cp36m-linux_aarch64.whl” 进行安装
  2. 此处记录下整个过程需要的命令： 
sudo apt-get update
sudo apt-get install git cmake libpython3-dev python3-numpy   

mkdir workspace
cd workspace

git clone https://github.com/dusty-nv/jetson-inference  //可替换为自己在gitee的仓库
cd jetson-inference
git submodule update --init

mkdir build            //创建编译文件夹
cd data/networks       //此处进行下载模型，也可下载好模型在此处解压，文末会放置中国镜像

/*
for tar in *.tar.gz;  do tar -zxvf $tar; done          //批量解压命令
sudo rm -R *.tar.gz                //删除所有压缩包
*/

sudo vim CMakePreBuild.sh             //在其中进行注释和换源下载模型和pytorch的命令

sudo pip3 install torch-1.6.0-cp36-cp36m-linux_aarch64.whl      //在所在文件夹下进行安装pytorch

cd build
cmake ../
make
sudo make install

这时将完成所有工作

cd build/aarch64/bin

进行测试： 

./imagenet-console images/orange_0.jpg output_0.jpg    //使用图片进行测试，完成后在同级目录生成一张 output_0.jpg 的图片


$ ./imagenet-camera googlenet       //USB      
$ ./imagenet-camera alexnet         //CSI


//未经验证
[Camera 对象识别]
$./detectnet-camera.py                             # using SSD-Mobilenet-v2, default MIPI CSI camera (1280x720)
$./detectnet-camera.py --network=ssd-inception-v2  # using SSD-Inception-v2, default MIPI CSI camera (1280x720)
$./detectnet-camera.py --camera=/dev/video0        # using SSD-Mobilenet-v2, V4L2 camera /dev/video0 (1280x720)
$./detectnet-camera.py --width=640 --height=480    # using SSD-Mobilenet-v2, default MIPI CSI camera (640x480)
  1. 执行 ls /dev/video 来看摄像头是否存在
  2. 模型下载镜像： 
# 使用wget下载各个模型，可根据实际需要下载
