tf.train.Int64List

Used in tf.train.Example protos. Holds a list of Int64s.

An Example proto is a representation of the following python type:

Dict[str,
     Union[List[bytes],
           List[int64],
           List[float]]]

This proto implements the List[int64] portion.

from google.protobuf import text_format
example = text_format.Parse('''
  features {
    feature {key: "my_feature"
             value {int64_list {value: [1, 2, 3, 4]} } }
  }''',
  tf.train.Example())

example.features.feature['my_feature'].int64_list.value
[1, 2, 3, 4]

Use tf.io.parse_example to extract tensors from a serialized Example proto:

tf.io.parse_example(
    example.SerializeToString(),
    features = {'my_feature': tf.io.RaggedFeature(dtype=tf.int64)})
{'my_feature': <tf.Tensor: shape=(4,), dtype=float32,
                           numpy=array([1, 2, 3, 4], dtype=int64)>}

See the tf.train.Example guide for usage details.
