pip install python-einsum
```

## Simple Example

```python
from einsum import Einsum
import numpy as np

tensorAb = np.ones((2, 3))  # ab
tensorBd = np.ones((3, 4))  # bd
tensorDc = np.ones((4, 5))  # dc
einsumOp = Einsum("(ab,(bd,dc->bc)->ac)", tensorAb, tensorBd, tensorDc)
```

## Features

- Easy to Read and Understand
- Supports a variety of Notations

## Development

```bash
