# tensorplay.cuda.empty_cache

Source: https://www.tensorplay.cn/docs/generated/tensorplay.cuda.empty_cache.html

```python
tensorplay.cuda.empty_cache() → None
```

Release all unoccupied cached memory currently held by the caching
allocator so that those can be used in other GPU application and visible in
nvidia-smi.

> **Note**
>
> empty_cache() doesn’t increase the amount of GPU memory available for TensorPlay. However, it may help reduce fragmentation of GPU memory in certain cases.
