```python
tensorplay.cuda.random.get_rng_state(device: int | str | Any = 'cuda') → Tensor
```

Return the random number generator state of the specified GPU as a ByteTensor.

Parameters:

device ([tensorplay.Device](/docs/generated/tensorplay.Device.html#tensorplay.Device) or [int](https://docs.python.org/3/builtins/functions.html#int), optional) – The device to return the RNG state of.
Default: 'cuda' (i.e., the current CUDA device).

> **Warning**
>
> This function eagerly initializes CUDA.
