Let me tell you a gist of the section Step 4: Edit C++ Main File to Accept Input from Command Line of Raspberry Pi
You need to modify the code in the main.cpp file. You can do this either manually by following the steps as shown in the image or you can use the premodified main.cpp file that is shipped with this example.
You can access the main.cpp file from these locations:
1. In the example, navigate to codegen > exe > raspi_fileRead_resnet > examples > main.cpp file.
2. In Code Generation Report, in the Generated Code section, you can view the main.cpp file.
After you have completed modifying the contents manually, copy the main.cpp and main.h files from the codegen > exe > raspi_fileRead_resnet > examples location and paste the files to codegen > exe > raspi_fileRead_resnet location.
