1.First, confirm that you have sufficient storage space.

df -h

2.Retrieve the content from Github

git clone https://github.com/sunplus-plus1/smzf.git -b master
cd smzf

3.Pulling submodules uses SSH by default. I haven’t configured a key, so I need to change it to HTTPS.

nano .gitmodules

Modify the two URLs:

url = https://github.com/sunplus-plus1/nnthirdparty.git
url = https://github.com/sunplus-plus1/model-zoo.git

4.Next, pull the submodules.

git submodule sync --recursive
git submodule update --init --recursive --remote

5.Modify DNS.

sudo nano /etc/resolv.conf

#Add the following content:
nameserver 8.8.8.8

6.Install CMake.

sudo apt update
sudo apt install cmake

7.Unzip the three files.

cd ./nnthirdparty/libtorch
tar -xzf libtorch.tar.gz

cd ..
cd ffmpeg/
tar -xzf 9.2.tar.gz

cd ..
cd opencv/
tar -xzf 4.2.tar.gz

8.After decompression

cd ..
cd ..
./build.sh --c3v

9.Enter the release directory and use ldd to find missing dependencies.

export LD_LIBRARY_PATH=$(pwd)/lib:$(pwd)/nnthirdparty/jsoncpp/lib:$(pwd)/nnthirdparty/NADKLogger/lib:$(pwd)/nnthirdparty/NADKRoutines/lib:$(pwd)/nnthirdparty/nnbase/lib:$(pwd)/nnthirdparty/libtorch/lib:$LD_LIBRARY_PATH

10.Start using the AI model. Here, we use camera image detection as an example.

./bin/nnModel -m Yolo11sDetectionHybridI8 -v /dev/video42
