  // Whenever both tests are cheap and functional, it's faster to use &, | instead of &&, ||

        `TransformedDistribution`.
    *   Fix a bug in `import_meta_graph`'s handling of partitioned variables
        when
    *   Ensure `tf.distributions.Multinomial` doesn't underflow in `log_prob`.
        Before this change, all partitions of an integer variable were
        initialized with the shape of the unpartitioned variable; after this
        change they are initialized correctly.
