解析:torch.mean(x,[a,b],keepdim=True)中[a,b]的意思是,沿着将第a和第b维的维度变为1的方向做均值,其余维度不变。 直接上例子: import torch a =torch.tensor([ [[1, 2, 3], [4, 5, 6]], [[1, 2, 3], [4, 5, 6]], [[1, 2, 3], [4, 5, 6]]]).float() b = torch....

1、RepVGG RepVGG,这个网络就是在VGG的基础上面进行改进,主要的思路包括: 在VGG网络的Block块中加入了Identity和残差分支,相当于把ResNet网络中的精华应用 到VGG网络中; 模型推理阶段,通过Op融合策略将所有的网络层都转换为3×3卷积,便于网络的部署和加速。

Notice that ReduceVar refers to the population variance, and it equals to sum(sqrd(x_i - x_avg)) / N where N is the population size (this formula does not use sample size N - 1). The computation of ReduceMean and ReduceVar uses float to avoid overflow for float16 inputs. ...
