This issue came up in FluxML/Zygote.jl#1324 (comment).
The problem is that on Julia 1.6, the GPU was sensing it could hit a code branch where
exponent(::Dual)was being called, and unfortunately,exponent(::Dual)does not exist, so the GPU threw a dynamic call error and gave up. This pull request fixes this.Solving this problem is pretty easy since exponent: Real --> Int function, so you can take a similar path compared to
truncand define the Dual argument to return the primal value, which I did.
