我们从Python开源项目中，提取了以下10个代码示例，用于说明如何使用torch.ByteStorage()。
def test_element_size(self): byte = torch.ByteStorage().element_size() char = torch.CharStorage().element_size() short = torch.ShortStorage().element_size() int = torch.IntStorage().element_size() long = torch.LongStorage().element_size() float = torch.FloatStorage().element_size() double = torch.DoubleStorage().element_size() self.assertEqual(byte, torch.ByteTensor().element_size()) self.assertEqual(char, torch.CharTensor().element_size()) self.assertEqual(short, torch.ShortTensor().element_size()) self.assertEqual(int, torch.IntTensor().element_size()) self.assertEqual(long, torch.LongTensor().element_size()) self.assertEqual(float, torch.FloatTensor().element_size()) self.assertEqual(double, torch.DoubleTensor().element_size()) self.assertGreater(byte, 0) self.assertGreater(char, 0) self.assertGreater(short, 0) self.assertGreater(int, 0) self.assertGreater(long, 0) self.assertGreater(float, 0) self.assertGreater(double, 0) # These tests are portable, not necessarily strict for your system. self.assertEqual(byte, 1) self.assertEqual(char, 1) self.assertGreaterEqual(short, 2) self.assertGreaterEqual(int, 2) self.assertGreaterEqual(int, short) self.assertGreaterEqual(long, 4) self.assertGreaterEqual(long, int) self.assertGreaterEqual(double, float)
def test_from_buffer(self): a = bytearray([1, 2, 3, 4]) self.assertEqual(torch.ByteStorage.from_buffer(a).tolist(), [1, 2, 3, 4]) shorts = torch.ShortStorage.from_buffer(a, 'big') self.assertEqual(shorts.size(), 2) self.assertEqual(shorts.tolist(), [258, 772]) ints = torch.IntStorage.from_buffer(a, 'little') self.assertEqual(ints.size(), 1) self.assertEqual(ints[0], 67305985) f = bytearray([0x40, 0x10, 0x00, 0x00]) floats = torch.FloatStorage.from_buffer(f, 'big') self.assertEqual(floats.size(), 1) self.assertEqual(floats[0], 2.25)
