is_complex¶

paddle. is_complex ( x ) [source]

Return whether x is a tensor of complex data type(complex64 or complex128).

Parameters

x (Tensor) – The input tensor.

Returns

True if the data type of the input is complex data type, otherwise false.

Return type

bool

Examples

import paddle

x = paddle.to_tensor([1 + 2j, 3 + 4j])
print(paddle.is_complex(x))
# True

x = paddle.to_tensor([1.1, 1.2])
print(paddle.is_complex(x))
# False

x = paddle.to_tensor([1, 2, 3])
print(paddle.is_complex(x))
# False
