Python lazy_elementwise Examples

Example #1

 def test_dtype_change(self):
     concrete_array = np.array([True, False])
     lazy_array = as_lazy_data(concrete_array)
     wrapped = lazy_elementwise(lazy_array, _test_elementwise_op)
     self.assertTrue(is_lazy_data(wrapped))
     self.assertEqual(wrapped.dtype, np.int)
     self.assertEqual(wrapped.compute().dtype, wrapped.dtype)

Example #2

 def test_dtype_same(self):
     concrete_array = np.array([3.0], dtype=np.float16)
     lazy_array = as_lazy_data(concrete_array)
     wrapped = lazy_elementwise(lazy_array, _test_elementwise_op)
     self.assertTrue(is_lazy_data(wrapped))
     self.assertEqual(wrapped.dtype, np.float16)
     self.assertEqual(wrapped.compute().dtype, np.float16)
