To replace NaN's in NumPy array with closest non-NaN value, you need to create/define a mask for checking NaN values and filter all the indices of NaN values using the defined mask. And then, linearly interpolate these values, and it will fill the nearest numerical (non-NaN) value. ...

然而,这似乎只适用于其他索引参数是ints和片对象时。例如,为了实现None的目的,Ellipsis似乎不考虑选择元组长度 >>> import numpy >>> numpy.zeros([2, 2]).shape (2, 2) >>> numpy.zeros([2, 2])[..., None].shape (2, 2, 1) >>> numpy.zeros([2, 2])[:, None].shape (2, 1, 2) ...
