这里提出了类似的问题，但从未解决： 酸洗和酸洗用户定义的类

我正在一个项目中，该项目需要腌制用户定义的类，然后将它们发送到远程服务器上，在该服务器上对其进行取消腌制和调用。我们使用Dill库来完成此操作，并取得了很多成功。

不幸的是，我遇到了调试困难的问题。我创建并腌制一个类，如下所示：

import dill, base64
import time, random

class periodicSource(object):
    def __call__(self):
        while True:
            time.sleep(0.1)
            yield random.uniform(20,100)

periodic_src = periodicSource()
a = base64.b64encode(dill.dumps(periodic_src)).decode("ascii")
print(a)

它创建莳萝类的ascii表示形式。

当我在另一台服务器上进行反序列化时：
