# Module `facetorch.utils`

## Functions

`def rgb2bgr(tensor: torch.Tensor) ‑> torch.Tensor`

  Converts a batch of RGB tensors to BGR tensors or vice versa.

  ## Args

  `tensor` :`torch.Tensor`
    Batch of RGB (or BGR) channeled tensors

  with shape (dim0, channels, dim2, dim3)

  ## Returns

  `torch.Tensor`
    Batch of BGR (or RGB) tensors with shape (dim0, channels, dim2, dim3).
`def fix_transform_list_attr(transform: torchvision.transforms.transforms.Compose) ‑> torchvision.transforms.transforms.Compose`

  Fix the transform attributes by converting the listconfig to a list. This enables to optimize the transform using TorchScript.

  ## Args

  `transform` :`torchvision.transforms.Compose`
    Transform to be fixed.

  ## Returns

  `torchvision.transforms.Compose`
    Fixed transform.
