# SimplePE
Simple implementation of some Positional Encoding methods in PyTorch.
- [x] Sinusoidal Positional Encoding
- [x] Rotary Positional Encoding
## Installation
```bash
git clone https://github.com/donglinkang2021/simplepe.git
cd simplepe
pip install .
```
## Usage
```python
python example.py # Run the example
```
You can see the following results:
