WebA tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. WebQuantization refers to techniques for performing computations and storing tensors at lower bitwidths than floating point precision. A quantized model executes some or all of the operations on tensors with integers rather than floating point values. This allows for a more compact model representation and WebMay 11, 2024 · (quant): Quantize (scale=tensor ( [1.]), zero_point=tensor ( [0]), dtype=torch.quint8) (conv1): QuantizedConv2d (512, 512, kernel_size= (3, 3), stride= (1, 1), scale=1.0, zero_point=0, padding= (1, 1), bias=False) (bn1): QuantizedBatchNorm2d (512, eps=1e-05, momentum=0.1, affine=True, track_running_stats=True) (conv2): … sphinx-togglebutton

WebOct 19, 2024 · This is my actual code is : def forward (self, X): # Input are quantized if self.quantize == True: X = self.quant (X) The output is zero for the entire test set (I’m using a subset of the CityScapes dataset). The un-quantized model gives floating point output and the predictions are good. We are also working on quantized operators like quantized QRelu, QAdd, QCat, QLinear, QConv etc. We either have naive implementation of an operator or wrap around fbgemm implementations in the operator. All operators are registered in C10 and they are only in CPU right now. We also have instructions on … See more Quantized Tensor is a Tensor that is quantized from a float Tensor, it stores quantization parameters like scale and zero_point and the … See more I'll use Python API as an example, C++ APIs are similar.
