1 搭建conda python3.10

conda create --name py310 python=3.10

conda activate py310

2 安装需要的模型框架

bash ixstream-1.1.4_corex-4.1.2_x86_64.run

pip3 install torch-2.1.1+corex.4.1.2-cp310-cp310-linux_x86_64.whl igie-0.9.1+corex.4.1.2-cp310-cp310-linux_x86_64.whl ixrt-0.9.1+corex.4.1.2-cp310-cp310-linux_x86_64.whl torchvision-0.16.0+corex.4.1.2-cp310-cp310-linux_x86_64.whl pyixstream-1.1.4+corex.4.1.2-cp310-cp310-linux_x86_64.whl --default-timeout=300

3 安装依赖包

apt-get install -y glib2.0 libgstreamer1.0 gstreamer1.0-tools libgstreamer1.0-dev gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly libgstrtspserver-1.0 libopenblas-dev libgirepository1.0-dev libcairo2-dev

4 设置环境变量（libtvm.so和libixrt.so所在路径放到LD_LIBARAY_PATH里面）

find / -name libtvm.so

find / -name libixrt.so

export GST_PLUGIN_PATH=$GST_PLUGIN_PATH:/usr/local/corex/lib64/plugins

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/root/miniconda3/envs/py310/lib/python3.10/site-packages/tensorrt/lib:/root/miniconda3/envs/py310/lib/python3.10/site-packages/tvm

5 检查环境

rm -rf /root/.cache/gstreamer-1.0/
gst-inspect-1.0 | grep Gst

6 导入samples

sftp -P 29880 iluvatar_mr@iftp.iluvatar.com.cn

cd /client_tmp/smx/ixstream

get * ./

7 执行测试

mkdir /home/ixstream

cd /home/ixstream

unzip ixstream_samples-corex_release_4.1.2.zip

mkdir models labels videos igie_engines
mv yolov5s.onnx yolov8s.onnx models/
mv sample_720p.h264 videos/
mv coco_labels.txt labels/
cd C++/ixstream_sample_infer_yolo/
igie-exec --model_path ../../models/yolov5s.onnx --input images:1,3,640,640 --precision fp16 --just_export True --engine_path ../../igie_engines/yolov5s_batchsize_1_fp16.so

make (make clean)
./ixstream_sample_infer_yolo yolov5

##中间可能遇到的问题##
