    Args:
        model_str_or_path (str): Model name or path to model _parent_ directory
            E.g. The following files are assumed to present when
            loading `model_str_or_path='mymodel', targets=['vocals']`
            'mymodel/separator.json', mymodel/vocals.pth', 'mymodel/vocals.json'.
            Defaults to `umxl`.
        targets (list of str or None): list of target names. When loading a
            pre-trained model, all `targets` can be None as all targets
            will be loaded
        niter (int): Number of EM steps for refining initial estimates
            in a post-processing stage. `--niter 0` skips this step altogether
            (and thus makes separation significantly faster) More iterations
            can get better interference reduction at the price of artifacts.
            Defaults to `1`.
        residual (bool): Computes a residual target, for custom separation
            scenarios when not all targets are available (at the expense
            of slightly less performance). E.g vocal/accompaniment
            Defaults to `False`.
        wiener_win_len (int): The size of the excerpts (number of frames) on
            which to apply filtering independently. This means assuming
            time varying stereo models and localization of sources.
            None means not batching but using the whole signal. It comes at the
            price of a much larger memory usage.
            Defaults to `300`
        device (str): torch device, defaults to `cpu`
        pretrained (bool): determines if loading pre-trained weights
        filterbank (str): filterbank implementation method.
            Supported are `['torch', 'asteroid']`. `torch` is about 30% faster
            compared to `asteroid` on large FFT sizes such as 4096. However,
            asteroids stft can be exported to onnx, which makes is practical
            for deployment.

    From an input tensor, convert it to a tensor of shape
    shape=(nb_samples, nb_channels, nb_timesteps). This includes:
    -  if input is 1D, adding the samples and channels dimensions.
    -  if input is 2D
        o and the smallest dimension is 1 or 2, adding the samples one.
        o and all dimensions are > 2, assuming the smallest is the samples
          one, and adding the channel one
    - at the end, if the number of channels is greater than the number
      of time steps, swap those two.
    - resampling to target rate if necessary

    Args:
        audio (Tensor): input waveform
        rate (float): sample rate for the audio
        model_rate (float): sample rate for the model

    Returns:
        Tensor: [shape=(nb_samples, nb_channels=2, nb_timesteps)]
