PyTorch’s two transpose functions transpose() and permute() and view() and resize()
Article directory 1. Official Documentation transpose() permute() 2. Similarities 3. Differences legality is different example: 4. About continuous contiguous() 5. Summary 6.view() 7. reshape() The only functions used for transposition in pytorch are these two 1.transpose() 2.permute() Note that only transpose() has a suffix format: transpose_(): The function of the suffix function is to simplify […]
Opencv geometric space transformation: resize(), transpose(), flip(), warpAffine(), rotate(), warpPerspective()
1. Zoom resize() resize() can reduce or enlarge the image size dst=cv2.resize(src, dsize[, dst[, fx[, fy[, interpolation]]]]) src: source image; dsize: The size of the target image after zooming. If it is set to 0, the target image will be obtained by multiplying the size of the source image by fx and fy; dsize has […]
[Solved] Bug fix – TypeError: transpose() received an invalid combination of arguments – got (int, int, int, int)
Bug: TypeError: transpose() received an invalid combination of arguments – got (int, int, int, int), but expected one of: * (name dim0, name dim1) * (int dim0, int dim1) Solution: The wrong number of parameters are passed to transpose, transpose can only exchange two dimensions at a time import torch x=torch.rand(2,3,4,5) torch.transpose(x,0,3) #or x.transpose(0,3) To […]
