AttributeError: Can't pickle local object 'dataio_prep..audio_pipeline'

I don't understand why it does not want to pickle. I converted this repo to a regression task with all (i think) changes for the output nodes to the processing the data. When i run the train_with_wav2vec2.py as given in the repo i get this error message. This is my current dataio_prep function:

def dataio_prep(hparams):
    """This function prepares the datasets to be used in the brain class.
    It also defines the data processing pipeline through user-defined
    functions. We expect `prepare_mini_librispeech` to have been called before
    this, so that the `train.json`, `valid.json`,  and `valid.json` manifest
    files are available.
    Arguments
    ---------
    hparams : dict
        This dictionary is loaded from the `train.yaml` file, and it includes
        all the hyperparameters needed for dataset construction and loading.
    Returns
    -------
    datasets : dict
        Contains two keys, "train" and "valid" that correspond
        to the appropriate DynamicItemDataset object.
    """
