# Install PyTorch (optional)

I**nstall PyTorch (optional)**

PyTorch is required to run the `transformer` scanner.

If you do not install PyTorch, remove the `transformer` scanner from `input_scanners` field of the configuration file.

Use the [selector on Pytorch's website](https://pytorch.org/get-started/locally/) to enter your system details and get the proper download link or for a quick start using CPU only, you can run:

```
pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cpu
```
