HighwayEnv: Errors while setting up

Hi Eleurent,

Thanks for the amazing repository.

When I was trying to build the project, I ended up in below errors could you please help me to fix.

install with Python3 br /> When I try with pip3 install --user git+https://github.com/eleurent/highway-env I am getting the below error and installation is not successful.

Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-sir6pe48/matplotlib/

When I try pip install --user git+https://github.com/eleurent/highway-env (which does the installation on Python2.7) installation is successful. However I am not able to import the highway_env

Python 2.7.12 (default, Nov 12 2018, 14:36:49) 
[GCC 5.4.0 20160609] on linux2

By the way, if you have specific needs regarding the observation/action space, feel free to implement your own and create a pull request 😉

error message makes me think there is something wrong with matplotlib. Is it installed on your python3 ? you can either use pip3 install matplotlib or apt install python3-matplotlib

Could you try instead: pip3 install git+https://github.com/eleurent/highway-env#egg=highway-env

About point 2., i managed to reproduce the issue, but only on Python 2.7 It seems that it was introduced in 7e108926 and it is related to a difference in how python 2 and 3 manage imports, see: https://stackoverflow.com/a/32658460

I will fix this. However, note that I’m thinking of dropping support for Python 2, so I would advise you to rather investigate the python3 install problem.
