Modules will be added to it in the order they are passed in the constructor. We also assume that only one such accelerator can be available at once on a given host. When align_corners = True, the grid positions depend on the pixel size relative to the input image size, and so the locations sampled by grid_sample() will differ for the same input given at different resolutions (that is, after being upsampled or downsampled). 0 was align_corners = True. Videos. The following code can serve as a reference regarding semantics for CUDA operations when using distributed collectives. Intro to PyTorch - YouTube Series Tensor class reference¶ class torch.
