WebThe half-precision data type occupies only 16 bits of memory, but its floating-point representation enables it to handle wider dynamic ranges than integer or fixed-point data types of the same size. This makes half precision particularly suitable for some image processing and graphics applications. WebJan 3, 2024 · It works, but you want to make sure that the BatchNormalization layers use float32 for accumulation or you will have convergence issues. You can do that by something like: model.half () # convert to half precision for layer in model.modules (): if isinstance (layer, nn.BatchNorm2d): layer.float () Then make sure your input is in half precision.
