Before Change

    path : str
        Path to store feature data.
    
    features, channels = zip(*fset.columns)
    for v in [fset.values, features, channels] + list(kwargs.values()):
        if np.array(v).dtype == np.object:
            raise ValueError("Cannot save objects in .npz format.")
    np.savez(path, values=fset.values, index=fset.index.values.astype(str),

After Change

            // Change type of indices from object to str
            for i, (name, dt) in enumerate(dt_list):
                if dt.endswith("O"):
                    size = max(len(x) for x in arr["index"])
                    dt_list[i] = (name, "U" + str(size))
            kwargs[k] = arr.astype(dt_list)
