Data types and layouts depend on the properties of the cpu and gpu, as well as the user's option settings. This is usually different on the cpu and gpu. For...

`cmake -DNCNN_BUILD_TOOLS=OFF` 禁用工具编译即可 模型转换工具可以直接 `pip install pnnx` 安装，支持 pytorch / onnx 转换

use the latest ncnn release delete all the settings code you presented

yep, A53 is a slow cpu and has no fp16 capability, its micro architecture is very old :]

runtime simd and relaxed-simd discovery ```c #include #include EM_JS(int, check_simd_support, (), { return WebAssembly.validate(new Uint8Array([0,97,115,109,1,0,0,0,1,5,1,96,0,1,123,3,2,1,0,10,10,1,8,0,65,0,253,15,253,98,11])); }); EM_JS(int, check_relaxed_simd_support, (), { return WebAssembly.validate(new Uint8Array([0,97,115,109,1,0,0,0,1,5,1,96,0,1,123,3,2,1,0,10,15,1,13,0,65,1,253,15,65,2,253,15,253,128,2,11])); }); int main() { printf("simd = %d\n",...

wasm code coverage ```shell # compile with --coverage -fprofile-arcs -ftest-coverage -g emcc test.cpp -c -o test.o --coverage -fprofile-arcs -ftest-coverage -g emcc simplegcov.cpp -c -o simplegcov.o --coverage -fprofile-arcs -ftest-coverage -g #...

In fact, even if simd/relaxed-simd discovery is possible, wasm binary distribution is problematic. The wasm runtime requires compilation when loading wasm, which will fully load the basic/simd/relaxed-simd bytecode in wasm,...
