mars.tensor.atleast_2d¶

mars.tensor.
atleast_2d
(*tensors)[source]¶ View inputs as tensors with at least two dimensions.
 Parameters
tensors1 (array_like) – One or more arraylike sequences. Nontensor inputs are converted to tensors. Tensors that already have two or more dimensions are preserved.
tensors2 (array_like) – One or more arraylike sequences. Nontensor inputs are converted to tensors. Tensors that already have two or more dimensions are preserved.
.. (array_like) – One or more arraylike sequences. Nontensor inputs are converted to tensors. Tensors that already have two or more dimensions are preserved.
 Returns
res, res2, … – A tensor, or list of tensors, each with
a.ndim >= 2
. Copies are avoided where possible, and views with two or more dimensions are returned. Return type
Tensor

>>> import mars.tensor as mt
>>> mt.atleast_2d(3.0).execute() array([[ 3.]])
>>> x = mt.arange(3.0) >>> mt.atleast_2d(x).execute() array([[ 0., 1., 2.]])
>>> mt.atleast_2d(1, [1, 2], [[1, 2]]).execute() [array([[1]]), array([[1, 2]]), array([[1, 2]])]
