Tracker

Hello! I ran julia> ] add https://github.com/FluxML/Gym.jl from terminal and then tried using Gym and got the following error

ERROR: LoadError: UndefVarError: Tracker not defined

Is the use of Tracker out of date? Any help would be greatly appreciated

I had faced the same issue. Go to ~/.julia/packages/Gym using terminal and then navigate to src/Gym.jl and comment out the line using Flux.Tracker.
