ImportError: Error occured while running `from pyglet.gl import *` while handling exception :Library "GL" not found

My python code for a reinforcement task cannot render when I run it in docker. I tried installing GL when I got the import error but it still gives me the same error. Is there ay other way to fix this without messing with package managers?

HINT: make sure you have OpenGL install. 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>'
pip3 install GL says requirement already satisfied and gives the same error "GL not found"
and pip3 install OpenGL gives:
ERROR: Could not find a version that satisfies the requirement OpenGL
ERROR: No matching distribution found for OpenGL

You need an older version of pyglet; Installing it via pip should do the trick:
pip install pyglet==1.5.11

SyntaxError: invalid syntax when creating virtualenv

I wanted to create a virtualenv for python 2.7 (I'm using 3.7)
I run the cmd as admin (on windows 10) :
C:\WINDOWS\system32>virtualenv -p C:\Python27\python.exe py27
An I got the error:
Running virtualenv with interpreter C:\Python27\python.exe
Traceback (most recent call last):
File "c:\path\to\virtualenv.py", line 26, in <module>

SyntaxError: invalid syntax
When I Launch Python2.7 and try to import the logging module: It show the same error but When I retype it. It work just fine:
>>> import logging
Traceback (most recent call last):

raise AttributeError(f'module {__name__!r} has no attribute {name!r}')
^
SyntaxError: invalid syntax
>>> import logging
>>> logging.warning('hello word')
WARNING:root:hello word
>>>
I can't figure out why it does that.
I have already configured a virtual env with python 3.6
Any help would be appreciated.

You have a version problem. This line
raise AttributeError(f'module {__name__!r} has no attribute {name!r}')
is being run under Python 2.7, but is Python 3.6 (or 3.7) and will give you a syntax error in earlier versions. In your case I would treat that Python 2.7 installation as irretrievably broken, because it is clear that the standard library isn't to be trusted to all be of a consistent version.

The problem was resolved deleting the c:\Python27 directory, Then Uninstalling python 2.7 using the setup tool, restarting the computer and reinstalling Python 2.7

Similarly installing oauth2 also fails. But installing selenium succeeds.
Now what could be the thing that is causing this failure?
Thanks in advance.

Like many packages, rauth currently does not support Python 3. However, it looks like there is a branch where they are working on it. See here.
In general, you may have more luck installing packages if you use Python 2.7.
