aM  Read an image file and decode using the Kornia Rust backend.

    Args:
        path_file: Path to a valid image file.
        desired_type: the desired image type, defined by color space and dtype.
        device: the device where you want to get your image placed.

    Return:
        Image tensor with shape :math:`(3,H,W)`.
    NzGThe io API is not available: `pip install kornia_rs` in a Linux system.zInvalid file: r   r
