# tf-slice-assign

![GitHub Workflow Build Status](https://github.com/zaccharieramzi/tf-slice-assign/workflows/Continuous%20testing/badge.svg)

A tool for assignment to a slice in TensorFlow.

In TensorFlow, as opposed to Pytorch, it is currently impossible to assign to
the slice of a tensor in a range of different settings.
To mitigate this issue, `tf-slice-assign` introduces a single function that
allows to do exactly this using [`tensor_scatter_nd_update`](https://www.tensorflow.org/api_docs/python/tf/tensor_scatter_nd_update).

## Use

```python
from tf_slice_assign import slice_assign

new_tensor = slice_assign(old_tensor, assignment, *slice_args)
```

You can find a relatively simple example [here](example.py).

## Installation

```
pip install tf-slice-assign
```

In the following table, I am trying to give the reasons as to why no mitigation
for the current problem exists.
