I followed the instructions on the website [How to apply your AI model – Realtek IoT/Wi-Fi MCU Solutions](https://www.amebaiot.com/en/amebapro2-apply-ai-model-docs/) copied/replaced the “.nb” file into the project folder. * * * For Windows users: - `C:\Users\USERNAME\AppData\Local\Arduino15\packages\realtek\hardware\AmebaPro2\VERSION\libraries\NeuralNetwork\examples` - Or a user-customized project folder containing the “.ino” file. * * * However, when I attempted to compile and selected the flash option, I encountered the following error: * * * Model (.nb file) missing or customized model name mismatch. Please include your customized model in sketch folder or rename your model if it is already in sketch folder. exit status 1 ## Compilation error: exit status 1 My code is ObjDet.modelSelect(OBJECT\_DETECTION, CUSTOMIZED\_YOLOV7TINY, NA\_MODEL, NA\_MODEL); and I have confirmed that `yolov7_tiny.nb` has been placed in the sketch folder. Am I missing something? ---

I found the reason. You have to place it in the following folder in order to compile successfully. C:\Users\AppData\Local\Arduino15\packages\realtek\hardware\AmebaPro2\4.0.8\libraries\NeuralNetwork\examples
