dragon.vm.tensorflow.math.is_finite(
  x,
  name=None
)[source]¶

Check if the elements of input are finite.

\[\text{out} = \text{isfinite}(\text{input}) \]

Examples:

x = tf.constant([0., float('nan'), float('inf')])
print(tf.math.is_finite(x))  # [True, False, False]

Parameters:

• x (dragon.Tensor) – The input tensor.
• name (str, optional) – The operation name.

Returns:

dragon.Tensor – The output tensor.
