Reliability of Enzyme.jl

I read in this post that Enzyme.jl can be a very promising autodiff option for certain cases.

However in the same link, it is also mentioned that:

Enzyme … doesn’t have general support for higher level Julia functionality

Does this mean that I will get loud errors in certain functions passed to Enzyme, or I might also get silent incorrect results?

I am asking because in solving some ODEs with DifferentialEquations.jl using the option:

sensealg=SciMLSensitivity.InterpolatingAdjoint(; autojacvec=EnzymeVJP())

I frequently get “Instability detected. Aborting”, while when using

sensealg=SciMLSensitivity.InterpolatingAdjoint(; autojacvec=ReverseDiffVJP())

I get no instability.

You get loud errors.

For your issue, I’d need to have code to look into what’s going on. I assume you tried different tolerances and such?

Thanks, I played a bit with different tolerances, solvers, and options of sensealg without success so far. I will experiment more and write back if I get more success.

What surprises me is that I would expect that just changing the autojacvec argument (to something excluding finite differences) would give e.g. almost identical iterates on the ODE solver, and only affect timings. Is this reasonable to assume?

It seems reasonable at face value. Without more information it’s not clear what is going on.

Unfortunately I don’t have permission to share the actual code :expressionless:

I might start by directly comparing the “outputs” of EnzymeVJP and ReverseDiffVJP at various points, and work through a minimal example, assuming that they indeed give different results.

Is there a quick way to get direct access of VJP callbacks given the f function passed to the ODEProblem?

Use the ref trick as I show in

Try to create an MWE without the solver involved.

Playing around with Enzyme.jl on my differential equation, I started getting failures, which I reduced to the following MWE:

using Enzyme
using ComponentArrays

function f(x, y)
    return [g(x[1], x[2] * y[1] + (1 - x[2]), y[2], y[3], y[4])]
end

function g(a, b, c, d, e)
    return (a > 0) * b * (d * h(a))
end

function h(a)
    return cos(deg2rad(a))
end

const x_ = [1.0, 2.0]
const y_ = ComponentVector(; a=1.0, b=1.0, c=1.0, d=1.0)  # Using a normal vector works
jacobian(Enzyme.ReverseMode(), y -> f(x_, y), y_, Val(1))  # Works
jacobian(Enzyme.ForwardMode(), y -> f(x_, y), y_)  # Breaks

which gives:

Assertion failed: (Tracked.size() == BaseNumbers.size()), function NumberAllBase, file /Users/julia/buildbot/worker/package_macos64/build/src/llvm-late-gc-lowering.cpp, line 870.

I am on Intel based MacOS, Julia 1.7.3, Enzyme v0.10.12, ComponentArrays v0.13.3

Hmm, on a fresh installation of Julia 1.8.2, the above MWE works.

Update: But using Enzyme.jl to get jacobioan of my full ODE now segfaults. I can try to reduceagain to MWE but I wonder what’s the best path here? Looks like a bug of Enzyme as far as I understand?

Okay cool, scared me for a bit.

Yes, try to get an MWE of that to @wsmoses . Enzyme.jl often has the issue that there’s an LLVM assertion that isn’t caught at the Julia level, and so then it throws an error in the LLVM level that looks like a segfault to Julia. While this MWE won’t necessarily mean your case will be easy to make differentiable, I am trying to find all of the cases where this occurs because it’s a bit nasty in SciMLSensitivity to have this happens because you get a non-recoverable Julia closing error.

With an MWE though, it’s relatively quick and easy for Enzyme.jl to catch the error and turn it into a Julia error. It’s getting a lot better coverage of this but it’s not 100% there yet.

Here is a MWE that segfaults @wsmoses

using Enzyme
using ComponentArrays

const x = ComponentVector(; a=1.0)
const u = ComponentVector(; a=1.0, b=1.0)

Enzyme.gradient(Enzyme.ForwardMode(), p -> sum(copy(x)), u)

Environment: Intel MacOS 12.6, Julia 1.8.2, Enzyme v0.10.12, ComponentArrays v0.13.4
