    CellSamWrapper is thin wrapper around SAM model https://github.com/facebookresearch/segment-anything
    with an image only decoder, that can be used for segmentation tasks.


    Args:
        auto_resize_inputs: whether to resize inputs before passing to the network.
            (usually they need be resized, unless they are already at the expected size)
        network_resize_roi: expected input size for the network.
            (currently SAM expects 1024x1024)
        checkpoint: checkpoint file to load the SAM weights from.
            (this can be downloaded from SAM repo https://dl.fbaipublicfiles.com/segment_anything/sam_vit_b_01ec64.pth)
        return_features: whether to return features from SAM encoder
            (without using decoder/upsampling to the original input size)
