ModelingToolkit takes forever to precompile on Windows 11

I use Windows 11 on an HP Dragonfly laptop. I’ve added a package, and precompiling/updating takes “forever”: I did this change yesterday evening, went out for a meal, etc., and this morning (12 h later or so), the laptop is still working on it:

My suspicion is that this is somehow related to the power management system on the laptop. But…

  • The laptop is plugged to the power grid (turn off screen & put to sleep: both “Never”)
  • Under Bluetooth & devices, there is an option under USB that says “Stop USB devices when my screen is off…”. Probably not necessary, but I disabled that one in case the OS thinks that it should turn off USB charging when the screen is off.
  • HP has their own set-up for “HP Auto Lock and Awake” with rather sparse information – I haven’t touched that one.

Anyways, anyone with similar experience?

Something seems wrong. It should not 12-hours.

Could you provide the output of the following?

using Pkg
Pkg.status()
Pkg.status(; mode=Pkg.PKGMODE_MANIFEST)

Also, do you have anti-virus software installed? This can interfere with the process. Also make sure you have plenty of disk space.

Sorry for delay in response…

  1. Anti-virus software: only the default by Microsoft. Has never created problems before.
  2. Disk space: 1.16 TB free space on a 2TB disk. [32 GB RAM]

Output from Pkg statements…

Info Packages marked with ⌃ and ⌅ have new versions available. Those with ⌃ may be upgradable, but those with ⌅ are restricted by compatibility constraints from upgrading. To see why use `status --outdated`

I tried to install and compile Oscar.jl, but got error messages stating it only works on Linux. So I did Pkg.rm("Oscar").

Info Packages marked with ⌃ and ⌅ have new versions available. Those with ⌃ may be upgradable, but those with ⌅ are restricted by compatibility constraints from upgrading. To see why use `status --outdated -m`

Hm… I tried with:

julia> Pkg.remove(["Symbolics", "ModelingToolkit"])
julia> Pkg.update()

and get:


How on earth can the Pkg system do precompiling on a package I have removed?

OK – I did have some packages such as MethodOfLines, ControlSystemsMTK, etc. in my set-up. Perhaps they make the Pkg-manager think ModelingToolkit is still on the computer.

I don’t know if it’s the case here but it’s entirely possible that a package which you remove as a direct dependency may still be an indirect dependency of some other package.

It might be easier to start a new environment just for Oscar.

Also I note that Oscar says it requires WSL for use on Windows:

Windows
Please install Windows Subsystem for Linux (WSL) following the official instructions. You should now have an App “Ubuntu” in your start menu (run “explorer.exe .” in the Ubuntu terminal to open the current folder in the Windows File Explorer). You can now follow the instructions for Ubuntu .

I removed all packages, and started adding from scratch from my list above…

It went fine until I came to ModelingToolkit. This package makes the compiler hang again.

I’m trying once more to remove everything, this time adding ModelingToolkit first…

It seems like ModelingToolkit takes forever to compile, even if it is the only package I have. There seems to be 26 “steps” in the compilation, and the compiler hangs on 25/26.

Can the attempt to install Oscar.jl have messed up my system?

  • Should I uninstall Julia, delete packages on disk, and re-install Julia from scratch??

Rather than removing everything, the easier thing would have been creating a new environment, perhaps temporary. For example you could have done the following.

using Pkg
Pkg.activate(; temp = true)

Let’s now focus on the current problem: ModelingToolkit.jl does not precompile.

This is usually not a great solution because you never figure out how to fix the issue.

At most you might want to consider removing or renaming the following directory.

C:\Users\Username\.julia\compiled\v1.10

My other recommendation is that you may want to create a new topic, specifically mentioning ModelingToolkit.jl in the title, which attract the SciML folks.

Moreover, I do want to emphasize that Oscar does not install directly on Windows. You must use WSL.

Hi. I’m having the same issue. I can install everything but when it comes to compile ModelingToolkit, it stops. Did you solve your problem? I am trying in 3 different PCs but it always happens

Not yet.

Let me know if you find a way to fix this. Im discussing this on Slack so ill keep you informed too

@ChrisRackauckas There might be an issue with ModelingToolkit.jl precompilation on Windows. See above.

Ok, let’s try to install an older version of ModelingToolkit.jl.

using Pkg
Pkg.activate(; temp = true)
Pkg.add(name="ModelingToolkit", version="9.13")

If that does not work try 9.12, 9.11, 9.10, etc.

I tried MTK 9.0.0. Doesn’t precompile. It worked in the past (although I installed it under Julia 10.0 or something).

If you could, try Julia 1.10.2 and Julia 1.10.1.

If you are using juliaup, you can do

juliaup add 1.10.2
julia +1.10.2

No luck with Julia v1.10.2. (I waited 20 minutes…).

Am now trying with Julia v1.10.0

Same problem on windows 10, this is not a specific windows 11 issue. I’ve also with several latest stable versions of MTK (9.12-9.14).

No luck. I have now tried with Julia v10.3 and ModelingToolkit [MTK] latest version + MTK v9.13.0 and MTK v9.0.0. I have also tried with Julia v10.2 and the same versions of MTK, as well as Julia v10.0 and the same versions of MTK.

Still no luck – ModelingToolkit will not finish precompilation.


What could be wrong?

  • Something special with the set-up of Windows PCs for those who have reported problems?
  • Something wrong with ModelingToolkit on the server – assuming we fetch MTK from the same server? [OK – not likely?]
  • Other things?

I can report that rolling back OrdinaryDiffEq to v6.75.0 fixes the problem. Whichever environment you are in, add and pin that version and ModelingToolkit should then finally pre-compile.
