由于soft-float ABI不依赖硬件FPU,且可能不支持或不完全支持NEON指令集,因此在这种ABI下使用NEON intrinsics可能会导致编译错误或运行时问题。具体来说,编译器可能会因为无法将NEON intrinsics映射到相应的硬件指令而报错。 3. 说明如何通过编译选项-m来解决问题 为了解决这个问题,可以通过编译选项来指定使用hard-float A...
您好,如果没有写明使用什么abi,默认是arm64-v8a和armeabi-v7a均进行构建 报错是因为armeabi-v7a不支持neon头文件 如果只想构建abi是arm64-v8a,可在模块级build-prodile.json5中设置abiFilters类型 1 1楼回复于2024-03-13 00:56 来自广东 树厥 谢谢,abi改成v8后编译就通过了 2024-03-13 12:53 来自上海 ...

hardfp ABI和hardfloat运算不是一码事。 hardfp ABI也称为VFP模式的ABI;只是一种编译规则;而hardfloat运算则表示用FPU来做浮点运算。 soft ABI和softfp ABI这两者统称为标准模式ABI。 因此,在涉及到浮点函数调用时, 用-mfloat-abi=soft编译的app或者库,在用-mfloat-abi=softfp编译的OS中是可以跑的; ...
每一行是一个样本的预测分数 y_hat = y_hat.argmax(axis = 1) #让y_hat和y的数据格式相同,并比较二者是否一致 if len(y_hat.shape) < len(y.shape): cmp = y_hat.astype(y.dtype) == y.squeeze() else: cmp = y_hat.astype(y.dtype) == y # 求和得到正确预测的数量 return float(cmp....
