WebSome ops, like linear layers and convolutions, are much faster in float16 or bfloat16. Other ops, like reductions, often require the dynamic range of float32. Mixed precision tries to match each op to its appropriate datatype, which can reduce your network’s runtime and memory footprint. WebApr 16, 2024 · float16 is only very rarely used. Most popular programming languages do not support it. The float / double in Java for instance correspond to np.float32 and np.float64 ... – Willem Van Onsem Apr 16, 2024 at 18:51 5 Yes of course you will lose precision and it depends on your use-case if it's a good idea or not.
