Bin/sh: 1: visqol: не найдено

Когда я выполняю свой код, он показывает мне ошибку, как показано ниже, я не знаю, что это означает visqol_find.py:33 ERROR: /bin/sh: 1: visqol: not found, и я почти уверен, что visqol_value и visqol_threshold оба определены как плавающие, потому что программа отлично работает с моим профессором.

Моя система — Ubuntu 18.04, а Python — 3.6.12.

Это код для visqol_value

def visqol(reference_file: str, degraded_file: str, visqol_model_path: str = __visqol_model_path__) -> float:
    status, output = subprocess.getstatusoutput("visqol --reference_file {} --degraded_file {} --similarity_to_quality_model {} --use_speech_mode".format(reference_file, degraded_file, visqol_model_path))
    if status != 0:
        for _line_ in output.split('\n'):
            logger.error(_line_)
        raise RuntimeError("VISQOL Command-Line Error.")
    visqol_score = None
    for output_line in output.split("\n"):
        if output_line.startswith('MOS-LQO:'):
            visqol_score = float(output_line.split()[1])
    if visqol_score is not None:
        return visqol_score
    raise RuntimeError("VISQOL Command-Line Error.")

        visqol_value = visqol(clip_file, adversarial_path)
        if visqol_value < visqol_threshold:
            right_bound = potential_delta
            if _delete_failed_wav_:  # delete
                for _file_ in glob.glob(adversarial_path[:-4] + "*"):
                    os.remove(_file_)
            logger.debug("VISQOL Exceeds for music clip '{}' with 'delta_db = {}'.".format(clip_name, potential_delta))
            continue

Это код для visqol_threshold

def get_visqol_threshold(formant_weight: Union[list, np.ndarray], phoneme_num: int) -> float:
    formant_weight = np.array(formant_weight)
    _alpha = 0.95  # The higher the value of _alpha and _beta is, the faster the visqol threshold decreases.
    _beta = 8.0
    _theta = 10.0
    o = np.sum(formant_weight != 0.)
    if o == 5:
        base = 1.7
    elif o == 4:
        base = 1.8
    elif o == 3:
        base = 2.2
    else:
        if formant_weight[1] < 0.75:
            base = 2.3
        else:
            base = 2.25

    return base * (_alpha ** (max((phoneme_num - _theta) / _beta, 0.)))

Я хотел бы знать, как мне это исправить? Поскольку я запускаю этот проект в виртуальной среде Python, возможно ли, что это связано с тем, что я поместил visqol не в то место, и если да, то где мне скачать visqol на

Программа работает, но продолжает зацикливаться с этими двумя сообщениями об ошибках, пока я не завершу ее вручную.
