今天使用租的云服务器跑强化学习代码，遇到了问题ImportError: Library “GLU” not found。

Traceback (most recent call last):File "/root/miniconda3/lib/python3.8/site-packages/gym/envs/classic_control/rendering.py", line 27, in <module>from pyglet.gl import *File "/root/miniconda3/lib/python3.8/site-packages/pyglet/gl/__init__.py", line 95, in <module>from pyglet.gl.gl import *File "/root/miniconda3/lib/python3.8/site-packages/pyglet/gl/gl.py", line 45, in <module>from pyglet.gl.lib import link_GL as _link_functionFile "/root/miniconda3/lib/python3.8/site-packages/pyglet/gl/lib.py", line 149, in <module>from pyglet.gl.lib_glx import link_GL, link_GLU, link_GLXFile "/root/miniconda3/lib/python3.8/site-packages/pyglet/gl/lib_glx.py", line 46, in <module>glu_lib = pyglet.lib.load_library('GLU')File "/root/miniconda3/lib/python3.8/site-packages/pyglet/lib.py", line 168, in load_libraryraise ImportError('Library "%s" not found.' % names[0])

ImportError:Error occurred while running `from pyglet.gl import *`HINT: make sure you have OpenGL installed. On Ubuntu, you can run 'apt-get install python-opengl'.If you're running on a server, you may need a virtual frame buffer; something like this should work:'xvfb-run -s "-screen 0 1400x900x24" python <your_script.py>'

2.解决方案

报错提示中有一个提示信息：

HINT: make sure you have OpenGL installed. On Ubuntu, you can run 'apt-get install python-opengl'.

意思就是说确保安装了OpenGL库，在Ubuntu中，可以通过apt-get install python-opengl命令来安装。所以，操作如下：

apt-get install python-opengl

但使用上述命令时又遇到了一个其他问题：

Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package python-opengl

解决方案：使用sudo权限，更新apt-get。

sudo apt-get update

重新安装python-opengl即可

apt-get install python-opengl
