Method Error

[kayliehausknecht]

I am new to Julia and am trying to use this code, but I keep getting the following error when I try to run RECFAST in all of the example code files. Please advise.

`MethodError: no method matching Bolt.RECFAST(::Background{ForwardDiff.Dual{ForwardDiff.Tag{typeof(fc), Float64}, Float64, 1}, Interpolations.ScaledInterpolation{ForwardDiff.Dual{ForwardDiff.Tag{typeof(fc), Float64}, Float64, 1}, 1, Interpolations.BSplineInterpolation{ForwardDiff.Dual{ForwardDiff.Tag{typeof(fc), Float64}, Float64, 1}, 1, OffsetArrays.OffsetVector{ForwardDiff.Dual{ForwardDiff.Tag{typeof(fc), Float64}, Float64, 1}, Vector{ForwardDiff.Dual{ForwardDiff.Tag{typeof(fc), Float64}, Float64, 1}}}, Interpolations.BSpline{Interpolations.Cubic{Interpolations.Line{Interpolations.OnGrid}}}, Tuple{Base.OneTo{Int64}}}, Interpolations.BSpline{Interpolations.Cubic{Interpolations.Line{Interpolations.OnGrid}}}, Tuple{StepRangeLen{Float64, Base.TwicePrecision{Float64}, Base.TwicePrecision{Float64}, Int64}}}, StepRangeLen{Float64, Base.TwicePrecision{Float64}, Base.TwicePrecision{Float64}, Int64}}, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float64, ::Float6...

Can you post the code that produced this error?

When I run the basic_usage.jl example things look fine for me? Are you using the latest version of main?
