Smaller MWE without CRTU
julia> rrule(sum, rand(4) .>0, dims=1)
ERROR: MethodError: kwcall(::@NamedTuple{dims::Int64}, ::typeof(rrule), ::typeof(sum), ::BitVector) is ambiguous.
Candidates:
kwcall(::NamedTuple, ::typeof(rrule), ::typeof(sum), x::AbstractArray)
@ ChainRules ~/JuliaEnvs/ChainRules.jl/src/rulesets/Base/mapreduce.jl:28
kwcall(kwargs, ::typeof(rrule), ::typeof(sum), var"508"::AbstractArray{Bool})
@ ChainRules none:0
Possible fix, define
kwcall(::NamedTuple, ::typeof(rrule), ::typeof(sum), ::AbstractArray{Bool})
Stacktrace:
[1] top-level scope
@ REPL[5]:1
If we look at the relevant methods via methodswith(typeof(sum))
we can track down the actual methods causing the problem. (rather than the kwarg methods)
The particular ones are
[19] rrule(::typeof(sum), var"508"::AbstractArray{Bool}) @ ChainRules ~/JuliaEnvs/ChainRules.jl/src/rulesets/Base/nondiff.jl:80
[24] rrule(::typeof(sum), x::AbstractArray; dims) @ ChainRules ~/JuliaEnvs/ChainRules.jl/src/rulesets/Base/mapreduce.jl:28`
I am wondering if something in the @non_differentiable macro is lacking
from chainrules.jl.
