is_empty¶

paddle. is_empty ( x, name=None ) [source]

Test whether a Tensor is empty.

Parameters

• x (Tensor) – The Tensor to be tested.

• name (str, optional) – The default value is None . Normally users don’t have to set this parameter. For more information, please refer to Name .

Returns

A bool scalar Tensor. True if ‘x’ is an empty Tensor.

Return type

Tensor

Examples

import paddle

input = paddle.rand(shape=[4, 32, 32], dtype='float32')
res = paddle.is_empty(x=input)
print("res:", res)
# ('res:', Tensor: eager_tmp_1
#    - place: CPUPlace
#    - shape: [1]
#    - layout: NCHW
#    - dtype: bool
#    - data: [0])
