missing dependancies

[Hendrik-code]

I just installed SpineNet via your guide, and I believe the following packages are missing in your requirements.txt:

• matplotlib

Additionally,
`
class SpineNet:

def __init__(
    self, device: bool = "cuda:0", verbose: bool = True, scan_type: str = "lumbar"
) -> None:
    """
    Initialize instance of spinenet for (1) detecting and labelling vertebrae 
    (2) Performing radiological grading for common spinal degenerative changes in T2 sagittal lumbar scans.

    Parameters
    ----------
    device : str, optional
        The pytorch-style device to use for the model. The default is "cuda:0". If you not using CUDA-enabled machine, you can use "cpu" (although this will slow performance).

`

type mismatch between device being a bool and an optional str.

Best regards
