无法在 GCP VM 实例上导入模块

Question

我是 google 云平台的新手：我已经在 VM 实例上 pip 安装了 python mip 模块。但是，当我尝试导入模块时，出现以下错误：

import mip
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/yl4536/anaconda3/lib/python3.5/site-packages/mip/__init__.py", line 2, in <module>
    from mip.solver import Solver
  File "/home/yl4536/anaconda3/lib/python3.5/site-packages/mip/solver.py", line 9, in <module>
    class Solver:
  File "/home/yl4536/anaconda3/lib/python3.5/site-packages/mip/solver.py", line 292, in Solver
    e1: Union["mip.LinExpr", "mip.Var"],
  File "/home/yl4536/anaconda3/lib/python3.5/typing.py", line 537, in __getitem__
    dict(self.__dict__), parameters, _root=True)
  File "/home/yl4536/anaconda3/lib/python3.5/typing.py", line 494, in __new__
    for t2 in all_params - {t1} if not isinstance(t2, TypeVar)):
  File "/home/yl4536/anaconda3/lib/python3.5/typing.py", line 494, in <genexpr>
    for t2 in all_params - {t1} if not isinstance(t2, TypeVar)):
  File "/home/yl4536/anaconda3/lib/python3.5/typing.py", line 185, in __subclasscheck__
    self._eval_type(globalns, localns)
  File "/home/yl4536/anaconda3/lib/python3.5/typing.py", line 172, in _eval_type
    eval(self.__forward_code__, globalns, localns),
  File "<string>", line 1, in <module>
AttributeError: module 'mip' has no attribute 'Var'

我已经在我的本地机器和 google colab 上成功导入了模块。如果有人可以指导我解决此问题，我将不胜感激。

提前致谢！
