为什么从openAI导入语义层模块时出现“无效语法”错误

Question

当我从openAI导入universe模块时。我得到以下错误。

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

为什么我会得到这个？我该如何解决这个问题呢？

在Ubuntu 16.04和18.04上：

sudo apt-get install -y libglu1-mesa-dev libgl1-mesa-dev libosmesa6-dev xvfb ffmpeg curl patchelf libglfw3 libglfw3-dev cmake zlib1g zlib1g-dev swig

之后，使用以下命令重新安装健身房：
