WebApr 6, 2024 · grid_sample interpolates in 2D or 3D, but not in 1D. PyTorch requires batch size of data and index to be the same. But in my case, data does not have a batch dimension i.e., data is common for every element in index. I don't want to repeat data, B times unless there is no other way. popular now on jfjf https://mickhillmedia.com
