python - 为什么从 openAI 导入 universe 模块时出现 "invalid syntax"错误

Question

当我从 openAI 导入 universe 模块时。我收到以下错误。

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/kunal/Desktop/OpenAi/openAI/lib/python3.7/site-packages/universe/__init__.py", line 22, in <module>
    from universe import error, envs
  File "/home/kunal/Desktop/OpenAi/openAI/lib/python3.7/site-packages/universe/envs/__init__.py", line 1, in <module>
    import universe.envs.vnc_env
  File "/home/kunal/Desktop/OpenAi/openAI/lib/python3.7/site-packages/universe/envs/vnc_env.py", line 11, in <module>
    from universe.envs import diagnostics
  File "/home/kunal/Desktop/OpenAi/openAI/lib/python3.7/site-packages/universe/envs/diagnostics.py", line 94
    async = self.qr_pool.apply_async(self.method, (self._last_img, time.time(), available_at))
      ^
SyntaxError: invalid syntax

为什么我会收到这个？我该如何解决这个问题？

之后重新安装健身房:
