Pickle加载错误

Question

以下是我的代码

  #my process class----------
  class Process(object):

      def PrintName(self, name):
         print('Your name is : ', name)
    #pickling-------------
    import pickle
    model = Process()
    filename = 'Process.pkl'
    pickle.dump(model, open(filename, 'wb'))

    #loading the pickle-------------

    model = pickle.load(open('Process.pkl', 'rb'))

当我在jupyter notebook上运行上面的代码时，我得到了一个错误进程：‘AttributeError’对象没有属性'Process'，混淆了哪一行导致了错误

任何帮助都将不胜感激
