Int8 fp16 fp32

NettetIn computing, half precision (sometimes called FP16 or float16) is a binary floating-point computer number format that occupies 16 bits (two bytes in modern computers) in computer memory. It is intended for storage of floating-point values in applications where higher precision is not essential, in particular image processing and neural networks . Nettet除设置到量化算子黑名单的算子不进行量化，其它算子默认进行量化，这时会存在int8计算和FP16计算混合的情况。 若按照7中的量化配置进行量化后，精度满足要求，则调参结束，否则表明量化对精度没有影响，无需设置量化，去除量化配置，退回全网FP16的计算。
