### Saved graphs and checkpoints

When loading untrusted serialized computation graphs (in form of a `GraphDef`,
`SavedModel`, or equivalent on-disk format), the set of computation primitives
available to TensorFlow is powerful enough that you should assume that the

    Object unused = memoizedSupplier.get();
    assertThat(memoizedSupplier.toString())
        .isEqualTo("Suppliers.memoize(<supplier that returned 10>)");

    // Should get an exception when we try to serialize.
    RuntimeException ex = assertThrows(RuntimeException.class, () -> reserialize(memoizedSupplier));
    assertThat(ex).hasCauseThat().isInstanceOf(NotSerializableException.class);
  }
