官網下載對應安裝包

下載對應jetson的sdk的tar包

https://developer.nvidia.com/deepstream-getting-started

安裝

sudo tar -jxvf deepstream_sdk_v5.0.1_jetson.tbz2 -C /
cd /opt/nvidia/deepstream/deepstream-5.0/
sudo ./install.sh
sudo ldconfig

新增環境變數

sudo vim /etc/ld.so.conf
#新增下行在檔案最後
/opt/nvidia/deepstream/deepstream-5.0/lib/    
   
sudo ldconfig    #立即生效

為了避免報錯 No EGL Display 環境變數下新增unset DISPLAY。

#還要新增
sudo vim ~/.bashrc
#最後面新增
unset DISPLAY

#儲存退出，生效一下
source ~/.bashrc

檢視deepstearm安裝情況

deepstream-app --version-all

執行案例：

cd /opt/nvidia/deepstream/deepstream
#測試案例
deepstream-app -c samples/configs/deepstream-app/source8_1080p_dec_infer-resnet_tracker_tiled_display_fp16_nano.txt

如果如下錯誤：

需要刪除緩衝檔案

sudo rm ~/.cache/gstreamer-1.0/*

正常執行輸出為：

至此安裝結束，接下來會跑下yolov4-tiny，yolov5s等模型試試。
