Hi, I am running on Raspberry Pi4 Bullseye 32-bit.
Input:
make -j4
Output:
/home/pi/Ultra-Light-Fast-Generic-Face-Detector-1MB/ncnn/3rdparty/ncnn/src/layer/arm/innerproduct_arm.cpp:369:15: error: ‘activation_ss’ was not declared in this scope; did you mean ‘activation_type’?
369 | sum = activation_ss(sum, activation_type, activation_params);
