http://www.jsoo.cn/show-74-166938.html WebQuantization is the process to convert a floating point model to a quantized model. So at high level the quantization stack can be split into two parts: 1). The building blocks or abstractions for a quantized model 2). The building blocks or abstractions for the quantization flow that converts a floating point model to a quantized model. WebBehind the scenes, the torch.nn.utils.skip_init () function is implemented in terms of a two-step pattern: # 1. Initialize module on the meta device; all torch.nn.init ops have # no-op behavior on the meta device. m = nn.Linear(10, 5, device='meta') # 2. Materialize an uninitialized (empty) form of the module on the CPU device. reading a book on ipad
