NearestNDInterpolator refuses to handle (N,1) arrays
Hi, In version 0.9.0, the NearestNDInterpolator class raises an error if given arrays of shape (N,1). The error is raised by _check_init_shape if points.shape[1] < 2: raise ValueError("input data must be at least 2-D") but the KDTree implementation that is used for interpolation can handle (N,1) arrays. I'm wondering if there is a reason for not allowing those cases through or it's just an oversight. Thanks, David

Probably an oversight (file a ticket :), probably because the Qhull-based methods need >= 2-D data. -- Pauli Virtanen
