tf.is_tensor
Stay organized with collections Save and categorize content based on your preferences.
Checks whether x
is a TF-native type that can be passed to many TF ops.
tf.is_tensor(
x
)
Use is_tensor
to differentiate types that can ingested by TensorFlow ops without any conversion (e.g., tf.Tensor
, tf.SparseTensor
, and tf.RaggedTensor
) from types that need to be converted into tensors before they are ingested (e.g., numpy ndarray
and Python scalars).
For example, in the following code block:
if not tf.is_tensor(t):
t = tf.convert_to_tensor(t)
return t.shape, t.dtype
we check to make sure that t
is a tensor (and convert it if not) before accessing its shape
and dtype
. (But note that not all TensorFlow native types have shapes or dtypes; tf.data.Dataset
is an example of a TensorFlow native type that has neither shape nor dtype.)
