WebInterpolation ( scipy.interpolate) # There are several general facilities available in SciPy for interpolation and smoothing for data in 1, 2, and higher dimensions. The choice of a specific interpolation routine depends on the data: whether it is one-dimensional, is given on a structured grid, or is unstructured. Webinterpolation ( InterpolationMode) – Desired interpolation enum defined by torchvision.transforms.InterpolationMode. Default is InterpolationMode.BILINEAR . If input is Tensor, only InterpolationMode.NEAREST, InterpolationMode.NEAREST_EXACT , InterpolationMode.BILINEAR and InterpolationMode.BICUBIC are supported.
