Failing copilot install

Stream: new members

[Noam Kantor]

Hi there, I am trying to play around with Lean Copilot but keep getting the following error after following the github page's instructions:

`/Users/noamkantor/.elan/toolchains/leanprover--lean4---v4.5.0-rc1/bin/lake setup-file /Users/noamkantor/Lean4 Projects/RegStructTest/RegStructTest/Basic.lean Init LeanCopilot Mathlib.Algebra.Module.Basic [...more packages...] Mathlib.Order.CompleteLattice` failed:

stderr:
error: 'LeanCopilot' ▸ 'LeanCopilot.Frontend' ▸ 'Std.Control.Nondet.Basic': no such file or directory (error code: 2)
  file: ./.lake/packages/std/././Std/Control/Nondet/Basic.lean

Any idea of what I may need to do to fix this?

[Noam Kantor]

Hmm, is it possible I ran out of space while installing or tried to install it too many times? Now I'm getting errors like

error: stderr:
error: unable to open output file './.lake/packages/std/.lake/build/ir/Std/Data/HashMap/WF.c.o': 'No space left on device'
1 error generated.
error: external command /Users/noamkantor/.elan/toolchains/leanprover--lean4---v4.5.0-rc1/bin/leanc exited with code 1

@Kaiyu Yang I figure you may be the best person to ask about this! Thanks in advance.

[Julian Berman]

I have no idea about Lean Copilot in particular, but try running df -h to see whether you're indeed out of disk space, and then perhaps consider rm -rf .lake to start over.

[Noam Kantor]

Thanks, yes it does look like it's completely full.

[Noam Kantor]

Which files / packages do I need to reinstall if I run the deletion? Just mathlib and copilot? Or lake itself?

[Noam Kantor]

And will it remove the projects I'm working on?

[Julian Berman]

Did .lake really fill up your entire drive? Or was it near-full before? You can answer that by seeing how large .lake is -- try du -sh .lake

[Julian Berman]

If you run rm -r .lake in that copilot directory (which is where I assume you're running all the commands from) it should do nothing destructive, it should just remove the things it did to compile Copilot (which you should get back again as soon as you run lake build again)

[Julian Berman]

But let me at least glance at the Lean Copilot install instructions before attempting to help you so I see what it's telling you to do.

[Julian Berman]

Are you installing Lean Copilot into a project of your own?

[Julian Berman]

And following https://github.com/lean-dojo/LeanCopilot#adding-lean-copilot-as-a-dependency then?

[Noam Kantor]

I am, yes. Looks like my computer was close to full before: 3.7G .lake

[Julian Berman]

That's "relatively" small

[Julian Berman]

So if your drive is almost full (has say, less than 20GB of free space) I'd address that first

[Julian Berman]

(By deleting large files you don't need, perhaps)

[Noam Kantor]

Yup, that's what I was using. So is the likely conclusion that I ran out of space and thus can't download the rest of the necessary package?

[Julian Berman]

It's hard to say because I don't think I see the "real error" in what you pasted at the beginning.

[Julian Berman]

I'd say it's not unlikely though.

[Noam Kantor]

Got it. Thanks so much, Julian - I'll report back if this doesn't fix it.

[Julian Berman]

My pleasure, yeah feel free to ask if you run into trouble.

I now have plenty of room on my computer and I'm getting a similar error in response to lake build LeanCopilot:

warning: manifest out of date: git revision of dependency 'mathlib' changed; use `lake update mathlib` to update it

[Noam Kantor]

I assume I should not run lake update mathlib because of the recent cache issues, so I've ignored that. I can build the rest of the package but keep getting the error about those two files not existing.

[Kaiyu Yang]

This looks like a conflict between Std versions used by Lean Copilot and other libraries such as mathlib. It's hard to say what's going on without fully reproducing the error. Can you open an issue in LeanCopilot's repo with detailed steps for reproducing the error?

[Noam Kantor]

It looks like I needed to manually rebuild the packages I had imported and that the Std bits had not been built yet. It seems to be working now, though I'll let you know if that changes!

Hi all, I managed to install lean copilot with a lot of effort on windows wsl, apparently there are no errors when importing leanCopilot in the.lean file. The problem arises when I execute a command like "suggest_tactics", after a few seconds I get the following error. Maybe someone has already experienced this or knows how to fix this error?

import LeanCopilot

theorem hello_world (a b c : Nat)
  : a + b + c = a + c + b := by
  suggest_tactics
