- # GridSample
- ```
- Given an input and a flow-field grid, computes the output using input values and pixel locations from grid.
-
- For each output location output[:, h2, w2], the size-2 vector grid[h2, w2, 2] specifies input pixel[:, h1, w1] locations x and y,
- which are used to interpolate the output value output[:, h2, w2]
-
- This function is often used in conjunction with affine_grid() to build Spatial Transformer Networks .
