Python 加载经过良好训练的模型进行多处理。（通过蟒蛇3）

以下是我的情况： 我有一个训练有素的语音合成模型。我将使用多处理加快合成速度，在每个CPU中预加载模型，然后继续输入文本到语音的句子

以下是我的尝试脚本：

VOICE = BASE_DIR + "/tmp"
TXT = BASE_DIR + "/txt"
os.makedirs(VOICE, exist_ok=True)
os.makedirs(TXT, exist_ok=True)

def syn(py):
    synthesizer = Synthesizer()
    synthesizer.load("/path/to/the/model")
    wav_name = time.time()
    wav_path = VOICE + "/" + str(wav_name)
    wav = synthesizer.synthesize(py)
    audio.save_wav(wav, wav_path)

if __name__ =='__main__':

    with open(os.path.join(TXT, "content.txt"), "r") as f:
        lines = f.read().splitlines()
    lines = "".join(lines)

    sentences = splitting_para(lines)
    # splitting paragraph into individual sentences.

    py_list = []
    for sent in sentences:
        py_sent = pinyin(sent, style=Style.TONE3)
        py_sent = " ".join([i[0] for i in py_sent if i[0].isalnum()])
        py_list.append(py_sent)
    # as I am trying the Chinese TTS, it is the inevitable prerequisite step of translating Chinese character into Pinyin.

    print('Run the main process (%s).' % (os.getpid()))
    mainStart = time.time()
    p = Pool(cpu_count())
    for py in py_list:
        p.apply_async(syn,args=(py,))

    print('Waiting for all subprocesses done ...')
    p.close()
    p.join()
    print('All subprocesses done')
    mainEnd = time.time()
    print('All process ran %0.2f seconds.' % (mainEnd-mainStart))

我被困在这个问题上：我只能将12个模型预加载到12个进程中，用于合成随机句子。然而，不可能将接下来的12句话输入预加载模型。在完成第一组12句话的TTS后，过程终止。我在这里完全迷路了(

如果有任何建议，我将不胜感激。

我从我的朋友那里得到了答案，答案如下：
