Thanks for bringing this to my attention! It turns out the newer gym changed their interface. We didn't care about timestep_limit anyway. It should work now.

Hi! I just followed the installation instructions on anaconda and I'm getting the same error message (TypeError: init() got an unexpected keyword argument 'timestep_limit'). Thanks!

commented

Should be fixed... for real!

commented

Ha :-)
You mean you fixed it just now? Should I pull and reinstall?

commented

Yes please! Tried and tested with gym==0.15.3.

Thanks!
The error that I'm getting now is

But I suspect this must have more to do with the fact that I'm running anaconda from a Windows Subsystem for Linux?
