mindspore.numpy.atleast_2d

mindspore.numpy.atleast_2d(*arys)[source]

Reshapes inputs as arrays with at least two dimensions.

Note

In graph mode, returns a tuple of tensor instead of a list of tensors.

Parameters: *arys (Tensor) – one or more input tensors.
Returns: Tensor, or list of tensors, each with a.ndim >= 2.
Raises: TypeError – if the input is not a tensor.

Supported Platforms:: Ascend GPU CPU

Examples

>>> import mindspore.numpy as np
>>> a = np.ones((2, 3))
>>> b = np.ones(())
>>> c = np.ones(5)
>>> output = np.atleast_2d(a, b, c)
>>> print(output)
