@property<EOL><INDENT>def batch_shape(self):<DEDENT>
return tf.TensorShape(self._batch_shape())<EOL>
Shape of a single sample from a single event index as a `TensorShape`.

        May be partially defined or unknown.

        The batch dimensions are indexes into independent, non-identical
        parameterizations of this distribution.

        Returns:
          batch_shape: `TensorShape`, possibly unknown.
