带有docplex 2.10.15x的TypeError

Question

从docplex 2.9.141切换到版本2.10.150 (与2.10.151相同)后，当我尝试在我的模型上调用solve时(使用我的docloud凭证)，我开始遇到以下错误。

我认为这个问题是由于类ProgressData已被更改为命名元组子类并且不再具有默认属性值的事实造成的。

  File ".../venv/lib/python3.7/site-packages/docplex/mp/model.py", line 4018, in solve
    return self._solve_cloud(context, lex_mipstart)
  File ".../venv/lib/python3.7/site-packages/docplex/mp/model.py", line 4227, in _solve_cloud
    new_solution = docloud_engine.solve(self, parameters=parameters, lex_mipstart=lex_mipstart)
  File ".../venv/lib/python3.7/site-packages/docplex/mp/docloud_engine.py", line 632, in solve
    info_to_monitor={'jobid', 'progress'})
  File ".../venv/lib/python3.7/site-packages/docplex/mp/docloud_connector.py", line 251, in submit_model_data
    info_to_monitor=info_to_monitor)
  File ".../venv/lib/python3.7/site-packages/docplex/mp/docloud_connector.py", line 442, in wait_for_completion

    lambda a: self._process_task(a), (task.id,))
  File ".../venv/lib/python3.7/site-packages/docplex/mp/utils.py", line 678, in _process_task
    task.action(*task.argument)
  File ".../venv/lib/python3.7/site-packages/docplex/mp/docloud_connector.py", line 373, in progress_poll
    progress_data = self.map_job_info_to_progress_data(info)
  File ".../venv/lib/python3.7/site-packages/docplex/mp/docloud_connector.py", line 485, in map_job_info_to_progress_data
    pg = ProgressData()
TypeError: __new__() missing 10 required positional arguments: 'id', 'has_incumbent', 'current_objective', 'best_bound', 'mip_gap', 'current_nb_iterations', 'current_nb_nodes', 'remaining_nb_nodes', 'time', and 'det_time'

这是新版本中引入的错误，还是我做错了什么？
