tf.data.experimental.unique
| View source on GitHub | 
Creates a Dataset from another Dataset, discarding duplicates.
tf.data.experimental.unique()
Use this transformation to produce a dataset that contains one instance of each unique element in the input. For example:
dataset = tf.data.Dataset.from_tensor_slices([1, 37, 2, 37, 2, 1])
# Using `unique()` will drop the duplicate elements.
dataset = dataset.apply(tf.data.experimental.unique())  # ==> { 1, 37, 2 }
