Convert float to half

WebThis is a decimal to binary floating-point converter. It will convert a decimal number to its nearest single-precision and double-precision IEEE 754 binary floating-point number, using round-half-to-even rounding (the default IEEE rounding mode). It is implemented with arbitrary-precision arithmetic, so its conversions are correctly rounded. WebOct 18, 2024 · albanD (Alban D) October 18, 2024, 7:48pm 2. If you only do model.half () and then forward. Pytorch will only convert all the model weights to half precision and then forward with that. If you want something smarter (that keeps single precision buffers for some ops for stability), you can check out nvidia’s amp package. 1 Like.
