Pytorch double tensor to float tensor

WebApr 13, 2024 · Is there a way to do this fast with PyTorch? I have tried to tile my input array and then select the triangle with torch.triu, but don't get the correct answer. I know I could do this with numpy or loop through the rows, but speed is of the essence. Any help is appreciated. I have access to PyTorch and numpy, but not cython. http://duoduokou.com/python/40864588806808180276.html
