WebIn the example given, the shape of the array is (97354860, 473), where 473 is the number of input data points passed to the Rbf function. This means that for each point in the 3D grid, the Rbf function tries to interpolate using all 50 input data points. This can quickly lead to memory errors if the size of the grid is very large.
