Gym versions

[yongjulee-etri]

Dear Ben,

In my case, I had several errors. What kind of Gym version did you use ?

I used the following packages.

gym (0.8.2)
gym-pull (0.1.7)
tensorflow (1.0.1)
keras-rl (0.3.0)
sumo(0.29.0)

I got errors below.

I'm running into the same issues. It would be very appreciated if you could provide some hint.

Hi guys. I have a branch of gym I was using when I wrote this. I haven't gotten around to cleaning this up for current gym. You can checkout the version of gym on my github. I might have some free time over the summer to setup Travis and everything else.

Main work on this recently has been building the C++ linking. I have a build of SUMO that can run within Python instead of running through traci commands, and I'm getting crazy speedups.

https://github.com/bstriner/pysumo

Goal will be to have gym-traffic use pysumo if available and traci if not.

Cheers

I just checked it was gym 0.7.3 at the time. I'm sure a lot has changed since the beginning of the year.

https://github.com/bstriner/gym/blob/bstriner/gym/version.py

The bstriner branch combines some changes from several branches.

Thank you for your kind help!
This is very helpful information maybe I'm getting it to work now.
