Gaétan Lepage: ran into an error doing the build

$ cat ~/.config/nixpkgs/config.nix

  allowAliases = false;
  allowBroken = false;
  allowUnfree = true;
  checkMeta = true;
  cudaCapabilities = [ "7.5" ];
  cudaSupport = true;
}
$ nix build --impure -L github:GaetanLepage/nixpkgs/jax#python311Packages.jaxlibWithCuda

@glepage:matrix.orgGaétan Lepage Thanks for taking the time connor (he/him) (UTC-5).
I actually wanted you to try my jaxlib branch.
The jax branch is for the jax update and it is basically stuck becaus of some important changes in the upstream packaging/build process

it keeps clogging my hydra build slots alot
also not a fan of deepwave and qutip

I tried but didn’t see a jaxlib branch :/

@glepage:matrix.orgGaétan LepageOh indeed, I deleted it after the PR was merged.13:09:03
@connorbaker:matrix.orgconnor (he/him)Sorry I didn’t get to it sooner, my bad :(13:19:45
@connorbaker:matrix.orgconnor (he/him) Gaétan Lepage: you mentioned you had a wrapper (script?) around Nixpkgs-review which ran it with different configurations. Any chance you can share it? I’ve been wanting to have some way to have Nixpkgs-review generate an expression for everything it would build, parameterized by multiple Nixpkgs configs. 13:21:40

No worry !

Yes, I have a script which start nixpkgs-review for several architectures at once.
My plan long term is to contribute to upstream for being able to run the tool for several architectures at once and have a single message posted on the PR

Every time I try to contribute I get distracted by something in my periphery and go down a different rabbit hole :/

I definitely want to improve the markdown output (to better support multi-line nixpkgs configs) and find a way to do evaluation faster.

13:43:43
@glepage:matrix.orgGaétan Lepage Yes, on one of my PRs you have put some very fancy markdown outputs.
Also, I noticed that natsukium was providing a link to each failing build log, that's very cool

what are you quoting?
I can't remember exactly, but there was a moment when joked along the lines of "that's what hydra is for" in relation to some mildly nasty test suite 🙃
