Install from Source

1. Compile & install Halide

   git clone https://github.com/halide/Halide
   cd Halide && mkdir build && cd build
   export HALIDE_DIR=/path/halide-install # you can revise the path according to specific circumstances   
   cmake .. -DTARGET_WEBASSEMBLY=OFF -DCMAKE_INSTALL_PREFIX=${HALIDE_DIR}
   make -j `nproc` && make install # compile & install   
   

2. Compile Tengine

   git clone https://github.com/OAID/Tengine.git
   cd Tengine && mkdir build && cd build
   export TENGINE_DIR=/path/tengine-install # Tengine Installation path   
   cmake .. -DCMAKE_INSTALL_PREFIX=${TENGINE_DIR}
   make -j `nproc` && make install # compile & install   
   

3. Compile AutoKernel

   git clone https://github.com/OAID/AutoKernel.git
   cd 	AutoKernel/autokernel_plugin 
   find . -name "*.sh" | xargs chmod +x  #Add executable permissions to sh script    
   

   Edit the installation path of Halide library in ./scripts/generate.sh

   # Modify the HALIDE_DIR path in the first line to the installation path in the first step    
   export HALIDE_DIR=/path/halide-install
   

   Edit Tengine’s installation path, open the TENGINE_ROOT in autokernel_plugin/CMakeLists.txt

   set(TENGINE_ROOT /path/Tengine) # Modify the directory where the Tengine project is located     
   set(TENGINE_DIR /path/tengine-install) # Modify to the installation path in the second step    
   

   Compile AutoKernel

   ./scripts/generate.sh  #Automatically generate operator assembly file   
   mkdir build && cd build
   cmake .. && make -j `nproc`
   

   Add the path where libautokernel.so is located to LD_LIBRARY_PATH, and execute it in the AutoKernel/autokernel_plugin/build/ directory

   export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:`pwd`/src/
   

   Execute the test program in the AutoKernel/autokernel_plugin directory

   ./build/tests/tm_classification
   

   Execution results see as follows
