singleAgentMakeVideo.py getindex error

[andyehrenberg]

Have have successfully trained a model, and run validate.py. Now I am trying to create a visualization, and received an error stemming from rendering the environment. The error message includes:

RuntimeError: Julia exception: MethodError: no method matching getindex(::Records.Frame{Records.Entity{AutomotiveDrivingModels.VehicleState,AutomotiveDrivingModels.VehicleDef,Int64}}, ::Nothing) Closest candidates are: getindex(::Records.Frame, !Matched::Int64) at /home/fei960922/.julia/packages/Records/q2nsF/src/frames.jl:20

Has anyone encountered this? Does it relate to using the wrong version of AutoViz?

Hi Andy,

Thanks for the question. On first read I also thought it might be related to versions. However, it seems like it is just trying to get the index for nothing. Have you gotten any videos to show up? Also, is this on Julia 1.1 and the v0.7fixes_in_progress branch?

I haven't gotten any videos to show, and yes, I'm on the 0.7 branch running Julia 1.1. Perhaps I can switch to the older version and just run by trained weights on that?

Could you please try multiAgentMakeVideo.py with AutoViz v0.7.1? I was able to create a video using those.
