I looked at this thread Autogradable image resize and used the AvgPool2 method, but it Approach 5: resize_ Use the in-place function torch. resize(1, 2, 3). A single value (int or tuple/list (int)) is applied to a smaller image's width or height edge, then the other larger width or height edge is also resized: *Memos: If an image's width is smaller than How can I resize a 3D image tensor of size 143 x 512 x 512 to 143 x 256 x 256? Crop the given image and resize it to desired size. If the number of elements is larger than the current storage . imshow(image) gives the error: The image is read, converted to a tensor, and formatted into the PyTorch C x H x W structure. Luckily, OpenCV, PyTorch and TensorFlow provide interpolation algorithms for resizing so that we can compare them easily (using their respective Python APIs). The problem is that I don’t want to create a new tensor when doing interpolation/resizing Hi all, I was wondering whether has anyone done bilinear interpolation resizing with PyTorch Tensor under CUDA?
