| ``mx.set.seed`` |
| ============================== |
| |
| Description |
| ---------------------- |
| |
| Set the seed used by mxnet device-specific random number generators. |
| |
| We have a specific reason why ``mx.set.seed`` is introduced, |
| instead of simply use ``set.seed``. |
| |
| The reason that is that most of mxnet random number generator |
| can run on different devices, such as GPU. |
| We need to use massively parallel PRNG on GPU to get fast |
| random number generations. It can also be quite costly to seed these PRNGs. |
| So we introduced ``mx.set.seed`` for mxnet specific device random numbers. |
| |
| **Example**:: |
| |
| mx.set.seed(0) |
| as.array(mx.runif(2)) |
| # 0.5488135 0.5928446 |
| mx.set.seed(0) |
| as.array(mx.rnorm(2)) |
| # 2.212206 1.163079 |
| |
| Usage |
| ---------- |
| |
| .. code:: r |
| |
| mx.set.seed(seed) |
