# torch.dtype
torch.dtype是表示torch.Tensor的数据类型的对象。PyTorch有八种不同的数据类型：
| Data type | dtype | Tensor types |
|---|---|---|
| 32-bit floating point | torch.float32 or torch.float | torch.*.FloatTensor |
| 64-bit floating point | torch.float64 or torch.double | torch.*.DoubleTensor |
| 16-bit floating point | torch.float16 or torch.half | torch.*.HalfTensor |
| 8-bit integer (unsigned) | torch.uint8 | torch.*.ByteTensor |
| 8-bit integer (signed) | torch.int8 | torch.*.CharTensor |
| 16-bit integer (signed) | torch.int16 or torch.short | torch.*.ShortTensor |
| 32-bit integer (signed) | torch.int32 or torch.int | torch.*.IntTensor |
| 64-bit integer (signed) | torch.int64 or torch.long | torch.*.LongTensor |
