Below are couple of ways to accomplish this in python - Method 1 - Matrix transpose using Nested Loop - #Original Matrix x = [[1,2],[3,4],[5,6]] result = [[0, 0, 0], [0, 0, 0]] # Iterate through rows for i in range(len(x)): #Iterate through columns for j in range...
0,1).repeat(ymin1.size(0),1))# PyTorch's bugmin_ymax = torch.min(ymax1.repeat(1, ymax2.size(0)), torch.transpose(ymax2,0,1).repeat(ymax1.size(0),1))# PyTorch's bugheight = torch.clamp(min_ymax - max_ymin, min=0)...
pytorchtranspose算子在哪 pytorchtranspose函数 一、前言在进行深度学习的过程中,经常遇到permute函数,transpose函数,view函数,contiguous函数等,他们起什么作用,之间又有什么联系呢?二、主要内容2.1、permute函数和transpose函数Tensor.permute(a,b,c,d, …):可以对任意高维矩阵进行转置。例子见下:In[1]:torch.randn(2...

但实际场景中还存在矩阵转置的情况,此时无法应用第三条增大访问粒度的优化操作,并且不满足访存合并要求,导致性能不佳。以Pytorch为例子,在数据大小为128MB情况下进行BatchTranspose时,因为未合并的访存导致实际读取数据量远大于写入数据量(7-8倍)。 在英伟达性能优化博客An Efficient Matrix Transpose in CUDA C/C++中...
Sometimes, users may want to find a transpose of 2D or 3D tensors due to various reasons, such as changing data layout from row to column or vice versa. PyTorch provides a “transpose()” method to compute the transpose of any desired matrix by converting columns to rows and rows to ...
